China remains one of the most important sourcing bases for aluminum extrusion equipment, particularly for buyers seeking complete press lines, auxiliary machinery, automation upgrades, and customized engineering support. For procurement managers, the right partner is not simply the supplier offering the highest press tonnage—it is the manufacturer that can deliver repeatable accuracy, stable hydraulic performance, verifiable quality control, practical installation support, and responsive service throughout the equipment lifecycle.
This guide reviews 10 notable Chinese extrusion equipment manufacturers and equipment suppliers for aluminum profile production. It is designed for professional buyers evaluating long-term partners for architectural profiles, industrial aluminum sections, photovoltaic frames, automotive components, rail transit profiles, electronics housings, and other precision extrusion applications.
China's extrusion market is supported by large domestic demand from construction, transportation, renewable energy, and lightweight vehicle manufacturing. Industry sources estimate that Chinese aluminum extrusion consumption reached approximately 22.87 million tonnes in 2025, while industrial-profile demand continues to grow alongside solar, EV, and advanced manufacturing applications.
The companies below were selected using practical sourcing criteria rather than brand recognition alone. Buyers should use the same framework when comparing extrusion equipment manufacturers.
| Evaluation dimension | What buyers should verify | Why it matters |
|---|---|---|
| Manufacturing capability | Press tonnage range, machining capacity, assembly area, in-house hydraulic and electrical integration | Determines whether the supplier can build and commission a stable production line |
| Engineering capability | Die-related know-how, billet heating, hydraulic circuit design, PLC controls, automation options | A press is only one part of a productive extrusion system |
| Quality management | Incoming-material inspection, machining inspection, pressure testing, factory acceptance testing | Reduces risk of premature leakage, alignment errors, and unstable production |
| Customization depth | Press layout, container size, die-slide configuration, runout table, puller, handling system, controls | Necessary for different alloys, section sizes, plant layouts, and automation needs |
| Delivery reliability | Production schedule, project milestones, installation plan, spare-parts commitment | Critical for plant expansion and line-replacement projects |
| Export readiness | CE documentation where applicable, English manuals, remote support, export packing, commissioning service | Helps overseas buyers reduce compliance and startup risk |
| Long-term service | Spare parts, troubleshooting response, technician availability, retrofit capability | Equipment performance depends on support after installation |
A reliable supplier should be willing to provide a technical proposal that specifies the extrusion force, billet diameter, container dimensions, extrusion ratio range, alloy scope, heating method, hydraulic components, electrical controls, safety system, auxiliary equipment, factory acceptance criteria, and warranty boundaries.
China's aluminum-processing supply chain gives equipment buyers access to a dense ecosystem of press builders, hydraulic-component suppliers, automation integrators, billet-heating specialists, die manufacturers, industrial furnace producers, and profile-processing companies.
Foshan and the wider Pearl River Delta are especially relevant for aluminum profile equipment procurement. The region has long served architectural aluminum, industrial profile, furniture hardware, doors and windows, photovoltaic framing, and export-oriented fabrication markets. This concentration enables equipment suppliers to gain practical feedback from active extrusion plants rather than developing machinery only from drawings.
For buyers, this ecosystem can offer several advantages:
- Faster access to complete extrusion-line configurations.
- More flexibility for customized layouts and capacity upgrades.
- Competitive pricing compared with many European or Japanese equipment packages.
- Shorter communication loops between press builder, die supplier, automation provider, and end user.
- A wider choice of suppliers for presses from small and medium production lines to large-tonnage industrial applications.
However, the market is not uniform. China has highly capable manufacturers as well as trading companies and assemblers with limited engineering depth. Buyers should distinguish between a supplier that designs, machines, assembles, tests, and supports the press, and one that mainly integrates outsourced components.
The following list is not a universal ranking by revenue or production volume. Instead, it highlights suppliers with different positioning, including flexible manufacturers for customized projects, larger press specialists, hydraulic equipment providers, and machinery companies serving specific segments of the aluminum extrusion market.
Founded: 2011
Location: Shishan Town, Nanhai District, Foshan, Guangdong, China
Core products: Aluminum extrusion presses, extrusion production-line equipment, customized aluminum profile extrusion systems
Press range: 700T to 7,500T aluminum extrusion presses
Target customers: Aluminum profile plants, industrial profile producers, PV-frame manufacturers, automotive-profile processors, growing regional extrusion businesses
OEM/ODM capability: High—customized press configuration, factory planning, line integration, and technical support
Foshan Sailixin Machinery Manufacturing Co., Ltd. is a practical choice for buyers seeking a customized aluminum extrusion press supplier with strong cost-performance positioning. Established in 2011, the company focuses on the research, development, and production of aluminum extrusion presses and related production-line solutions.
Sailixin reports more than 1,400 sets sold in domestic and overseas markets, a 50,000-square-meter industrial park, nearly 30 R&D personnel, and an independently developed 700T–7,500T press range. The company also states that its short-stroke press models have an annual production capacity of 100 sets per model category.
Rather than positioning itself only for very large corporations, Sailixin is particularly relevant to small and medium-sized aluminum profile manufacturers that need a responsive supplier capable of adapting equipment to their plant layout, alloy requirements, and investment budget. This can be valuable for buyers building a first extrusion line, replacing aging presses, expanding output, or adding a dedicated line for solar, automotive, electronics, or industrial sections.
Key strengths include:
- Customized aluminum extrusion press configurations from 700T to 7,500T.
- Whole-line planning support covering press selection, layout, auxiliary equipment, installation, and commissioning.
- In-house focus on hydraulic, mechanical, and electrical control integration.
- Quality procedures that include raw-material inspection, dimensional reinspection during machining, and pre-shipment equipment testing.
- Experience serving domestic and international customers.
- Flexible communication for buyers requiring OEM-oriented engineering changes and non-standard line design.
Sailixin states that it uses flaw detection and other inspection methods for incoming materials, conducts process-by-process dimensional checks, and debugs the complete machine before shipment. Its extrusion systems are intended for building profiles, general industrial profiles, new-energy vehicle profiles, photovoltaic profiles, and electronic-product applications.
For procurement managers, Sailixin's main value is not only its press-tonnage range. It is the ability to combine a standard platform with customized engineering support. A buyer may need a different container diameter, billet length, die-heating arrangement, puller configuration, runout-table length, cooling system, or PLC interface. These details influence actual throughput and operational stability more than a headline tonnage figure alone.
Location: Wuxi, Jiangsu, China
Core products: Aluminum extrusion presses and supporting equipment
Target customers: Medium- and large-scale aluminum extrusion plants
OEM/ODM capability: Moderate to high, depending on line scope
Wuxi Weite Machinery is widely referenced in the aluminum extrusion press market as a Chinese manufacturer of extrusion equipment. The company is associated with larger-scale aluminum extrusion press solutions and is often considered by buyers looking for equipment beyond entry-level architectural-profile production.
Wuxi's industrial base offers access to precision machining, hydraulic systems, automation technology, and metalworking supply chains. Buyers evaluating Wuxi Weite should focus on the supplier's current press range, installed references for their target alloy and profile type, and the technical support available in the destination market.
Recommended verification questions include:
- What press models have been exported to markets with similar production conditions?
- Which hydraulic components are supplied as standard?
- Can the supplier provide reference data for cycle time, extrusion speed, and energy consumption?
- What is included in the electrical control system and remote-diagnosis package?
- How quickly can critical seals, pumps, valves, and sensors be delivered overseas?
Location: Taiyuan, Shanxi, China
Core products: Heavy machinery, forming equipment, large industrial systems
Target customers: Large industrial projects and high-capacity production facilities
OEM/ODM capability: Project-based engineering support
Taiyuan Heavy Industry is a major Chinese heavy-equipment manufacturer with experience in large-scale industrial machinery. For aluminum extrusion buyers, the company is more relevant to capital-intensive projects requiring substantial engineering capacity, heavy-duty manufacturing capability, and formal project-management structures.
Buyers considering large-tonnage extrusion presses should evaluate whether the proposed equipment is designed for their real operating conditions, especially when handling large billets, difficult alloys, thick-wall sections, or demanding industrial profiles.
A large press supplier may be appropriate when a project requires:
- High extrusion force for larger billet diameters.
- Heavy-duty containers and stems.
- Long-term support for industrial-scale production.
- Integration with automated billet handling and downstream equipment.
- Formal documentation for engineering review and project acceptance.
Location: China
Core products: Heavy industrial equipment and forming machinery
Target customers: Large industrial manufacturers and engineering projects
OEM/ODM capability: Engineering-oriented, subject to project scale
China National Heavy Machinery Corporation is associated with heavy machinery and industrial equipment manufacturing. It can be relevant for buyers seeking large-scale, engineered systems rather than standard compact extrusion presses.
For overseas procurement, buyers should pay particular attention to export-project coordination. Large equipment requires clear definitions for shipping scope, machine foundation, civil works, site utilities, installation responsibilities, commissioning duration, and acceptance testing.
A complete quotation should separate:
- Ex-works machine price.
- Optional auxiliary equipment.
- Packaging and export preparation.
- Ocean freight or port handling.
- Installation supervision.
- Electrical commissioning.
- Training.
- Spare-parts kits.
- Warranty service.
Location: China
Core products: Aluminum extrusion presses and related production equipment
Target customers: Aluminum profile and industrial extrusion plants
OEM/ODM capability: Customized press and line options
Xinxinke is included in market references covering global aluminum extrusion press manufacturers and Chinese equipment suppliers. It may be considered by buyers comparing domestic alternatives for complete press solutions.
As with any supplier, purchasers should avoid comparing only listed tonnage. The same nominal extrusion force can produce very different results depending on container alignment, stem rigidity, hydraulic response, billet-temperature uniformity, die condition, and downstream handling efficiency.
Before issuing a purchase order, ask the supplier for:
- Press force and nominal pressure data.
- Main-cylinder bore and stroke.
- Container internal diameter and heating method.
- Die-slide type and die-changing sequence.
- Main-pump brand, valve system, and filtration specification.
- PLC, HMI, servo, and inverter brands.
- Electrical schematic and safety-interlock logic.
- Recommended preventive-maintenance schedule.
- Guaranteed production metrics under defined operating conditions.
Founded: 1902
Location: Shanghai, China
Core products: Energy equipment, industrial machinery, automation-related systems
Target customers: Large industrial projects and advanced manufacturing groups
OEM/ODM capability: Primarily large-project and engineered-system support
Shanghai Electric is a large industrial equipment group with broad engineering capabilities. It is more likely to be relevant for buyers requiring high-level project management, industrial-system integration, or machinery connected to large manufacturing investments.
For extrusion-equipment buyers, the company's value lies in its scale and engineering resources rather than small-batch flexibility. It may be better suited to complex industrial projects than to a buyer seeking a compact, highly customized press for a narrow profile category.
Procurement teams should confirm the exact business unit responsible for aluminum extrusion equipment and request direct evidence of comparable installed projects. Large groups often have multiple divisions, so the relevant factory, service team, and product responsibility should be clearly identified.
Location: Wuxi, Jiangsu, China
Core products: Aluminum extrusion presses, hydraulic presses, ancillary extrusion-line machinery
Target customers: Architectural and industrial aluminum profile producers
OEM/ODM capability: Often high for line layout and auxiliary equipment
Wuxi is one of China's established machinery-manufacturing regions and has a concentration of equipment makers serving aluminum processing. Buyers may find several specialized suppliers offering presses, billet heaters, pullers, cooling tables, runout tables, die-heating furnaces, aging ovens, and handling systems.
The opportunity is supplier choice. The risk is uneven quality. Some suppliers may have strong machining capabilities but limited overseas service experience; others may provide attractive quotations but use lower-grade hydraulic components or simplified control systems.
To reduce risk, buyers should request a virtual or physical factory audit covering:
- CNC machining centers and boring machines.
- Hydraulic assembly and pressure-test area.
- Electrical cabinet workshop.
- Machine assembly space.
- Quality-inspection equipment.
- Finished press units under testing.
- Export-packing process.
- Spare-parts inventory.
- Installed customer references.
Location: Foshan, Guangdong, China
Core products: Aluminum extrusion presses, profile handling systems, aging ovens, cooling equipment, mold-heating systems
Target customers: Architectural aluminum processors, furniture-profile manufacturers, solar-profile producers, export-oriented profile plants
OEM/ODM capability: Often strong in layout customization and line integration
Foshan is particularly important for buyers sourcing aluminum-profile equipment because it sits close to a large downstream aluminum-processing market. Equipment providers in this region are often familiar with the practical needs of architectural profiles, doors and windows, decorative sections, furniture aluminum, industrial profiles, and solar frames.
The benefit of sourcing in Foshan is that buyers can compare multiple related suppliers during a single audit trip: extrusion press manufacturers, die makers, profile fabricators, surface-treatment equipment suppliers, aging-furnace builders, and packaging-equipment providers.
However, buyers should not assume every Foshan supplier is a true manufacturer. Verify whether the company owns its production facility and whether the quotation is based on internally engineered equipment or sourced assemblies.
Foshan Sailixin represents the more manufacturing-focused end of this category, offering dedicated aluminum extrusion presses and complete-line planning rather than simply brokering individual equipment items.
Location: Jiangsu Province, China
Core products: Hydraulic presses, extrusion equipment, industrial automation systems
Target customers: Buyers seeking medium-to-large press capacity and mechanical manufacturing depth
OEM/ODM capability: Varies by factory
Jiangsu remains an important equipment-manufacturing region because of its proximity to heavy industry, advanced machining, hydraulic-system suppliers, and export infrastructure. Some manufacturers in the province focus on standard aluminum extrusion presses, while others serve broader metal-forming applications.
For procurement managers, the most important distinction is whether the supplier has demonstrated aluminum-extrusion experience. A general hydraulic press builder may understand cylinder design and frame fabrication but may lack expertise in extrusion-specific requirements such as:
- Container alignment and deformation control.
- Dummy block performance.
- Die-slide reliability.
- Billet-temperature management.
- Extrusion speed control.
- Butt shear operation.
- Runout-table synchronization.
- Puller coordination.
- Handling of surface-sensitive aluminum profiles.
A successful aluminum extrusion press is a system, not merely a hydraulic frame.
Location: Multiple Chinese industrial clusters
Core products: Turnkey aluminum extrusion plants, presses, billet heating, cooling, handling, aging, automation, and profile-processing systems
Target customers: New plants, capacity-expansion projects, and investors requiring a single project interface
OEM/ODM capability: High at the system-design level
Turnkey suppliers can be attractive for buyers who want one main contractor responsible for production-line design. A complete package may include the extrusion press, hot-log shear, billet heater, die-heating furnace, puller, runout table, cooling bed, stretcher, saw, aging oven, material-handling equipment, and electrical automation.
The main advantage is coordination. When one supplier designs the line, the interface between machines can be better controlled. The main risk is that some turnkey providers outsource many elements and may have limited control over component quality or after-sales support.
For a turnkey project, buyers should request a responsibility matrix clearly stating who is accountable for:
| Project area | Questions to include in the contract |
|---|---|
| Production capacity | What output is guaranteed per shift, month, or year? |
| Product scope | Which alloys, billet sizes, profile sizes, and wall thicknesses are covered? |
| Utilities | What are the required electrical load, compressed air, cooling water, and gas specifications? |
| Installation | Who provides technicians, tools, lifting support, and local labor coordination? |
| Commissioning | How many days are included, and what happens if production targets are not achieved? |
| Training | Is training provided for operators, maintenance staff, electricians, and hydraulic technicians? |
| Spares | Which critical parts are included for 12 to 24 months of operation? |
| Warranty | What parts and labor are covered, and what exclusions apply? |
The table below provides a practical procurement comparison. Exact capacity, MOQ, and certification status should always be reconfirmed directly with each supplier because machinery projects are typically customized.
| Manufacturer or supplier type | Main focus | Typical project scale | MOQ | Certification and documentation focus | Suitable buyer profile |
|---|---|---|---|---|---|
| Foshan Sailixin Machinery Manufacturing Co., Ltd. | 700T–7,500T aluminum extrusion presses and complete line planning | Small to large customized lines | 1 set | ISO 9001 stated; technical drawings, QC and factory testing documentation | Buyers seeking flexibility, custom design, responsive communication, and cost-controlled projects |
| Wuxi Weite Machinery | Aluminum extrusion presses and supporting machinery | Medium to large | 1 set | Confirm current ISO, CE, and export documentation by model | Established profile plants seeking specialized press options |
| Taiyuan Heavy Industry | Heavy industrial forming equipment | Large industrial projects | 1 project | Engineering documentation and project-based compliance | Large manufacturers and capital-intensive industrial projects |
| China National Heavy Machinery | Heavy machinery and engineered systems | Medium to large | 1 project | Confirm project-specific documentation | Buyers requiring heavy-duty equipment and formal project delivery |
| Xinxinke Extrusion Equipment | Aluminum extrusion press systems | Small to large | 1 set | Confirm current quality-management and export certificates | Buyers comparing domestic press alternatives |
| Shanghai Electric | Large industrial equipment and engineering | Large | 1 project | Project-specific compliance and documentation | Complex industrial or high-budget projects |
| Wuxi specialized suppliers | Presses and auxiliary equipment | Small to large | 1 set | Quality systems vary by factory | Buyers able to conduct detailed factory audits |
| Foshan line integrators | Complete profile-production solutions | Small to medium | 1 set | Documentation quality varies | Architectural and solar-profile producers |
| Jiangsu hydraulic press manufacturers | Hydraulic and metal-forming machinery | Medium to large | 1 set | Verify extrusion-specific testing and compliance | Buyers seeking custom hydraulic equipment |
| Turnkey line suppliers | Full extrusion plant integration | Medium to large | 1 project | Contract-based technical, safety, and export documentation | Investors and new-plant projects |
Sailixin states that it holds ISO 9001 certification and identifies itself as a national high-tech enterprise. Buyers should request the current certificate number, issuing body, scope, and validity dates before finalizing procurement.
A vague request such as "Please quote a 1,800-ton extrusion press" is not enough for a reliable offer. Suppliers can only engineer the right system when buyers provide the production context.
A technical inquiry should include the following information:
- Aluminum alloy grades, such as 6063, 6061, 6005A, 6082, 6060, 7005, or other grades.
- Billet diameter and billet length.
- Maximum circumscribed-circle diameter of the profile.
- Maximum profile weight per meter.
- Required wall thickness range.
- Hollow, semi-hollow, or solid profile ratio.
- Target annual output.
- Desired extrusion speed.
- Surface-finish requirements.
- Downstream process requirements, including powder coating, anodizing, thermal break, machining, or aging.
- Local power supply and frequency.
- Required safety and documentation standards.
- Destination country and expected installation conditions.
For standard architectural profiles, buyers may prioritize output, surface quality, and production economy. For industrial, automotive, photovoltaic, rail, or electronics profiles, the equipment requirements can be more demanding.
Important technical considerations include:
- Container design: The container must match billet diameter and maintain alignment under repeated pressure cycles.
- Hydraulic stability: Pressure fluctuations can affect extrusion speed, profile quality, and die life.
- Short-stroke design: A short-stroke configuration can reduce non-productive movement and improve operating efficiency when correctly matched to the application.
- Billet heating: Uniform billet temperature affects metal flow, surface quality, die wear, and scrap rates.
- Die heating: Inconsistent die temperature can lead to poor metal flow, tearing, pickup, and dimensional instability.
- Puller synchronization: For thin-wall, long, or surface-sensitive profiles, the puller must work with the extrusion speed rather than distort the section.
- Cooling control: Incorrect cooling can affect mechanical properties, straightness, and aging performance.
- Automation: PLC controls, sensors, HMI design, and data collection affect repeatability and maintenance efficiency.
For export projects, buyers may also require equipment designed around CE-related machinery safety principles, electrical-safety requirements, guarding, emergency stops, manuals, and risk-assessment documentation. RoHS is usually more relevant to electrical and electronic products than to the core mechanical extrusion press itself, but buyers may still need compliant electrical components or documentation depending on the destination market and project specification.
A supplier may quote a press by nominal tonnage but provide limited information about hydraulic response, container rigidity, stroke speed, or control accuracy. This can create problems during production of thin-wall, wide, hollow, or high-value industrial profiles.
How to avoid it: Request a complete technical datasheet, including maximum working pressure, extrusion speed range, return speed, container dimensions, cylinder dimensions, die-slide details, hydraulic-component brands, and installed-reference cases for similar profiles.
The hydraulic system is a critical cost and reliability area. An unusually low quotation can result from lower-grade seals, pumps, valves, filters, sensors, and hoses. The machine may run initially but later suffer from leakage, overheating, unstable pressure, or difficult maintenance.
How to avoid it: Ask for a brand list and bill of materials for major hydraulic and electrical components. Specify acceptable alternatives in the contract and require written approval before substitutions.
Some buyers receive a CE label but do not receive a declaration, risk assessment, wiring diagrams, safety documents, English manuals, or machine-specific safety features.
How to avoid it: Request the exact compliance documents before shipment. Verify whether the CE declaration applies to the complete machine or only to individual purchased components.
A supplier can show attractive videos of machinery without proving that it owns the production process. Some companies show another factory's equipment or only final assembly.
How to avoid it: Ask for a live video audit that includes the company sign, machining workshop, assembly area, current production orders, quality-inspection process, electrical-panel workshop, and finished-machine test area.
Some quotations appear low because they cover only the press body. Buyers later discover that they still need a billet heater, hot-log shear, die oven, puller, cooling table, stretcher, saw, aging oven, handling system, installation service, and spare parts.
How to avoid it: Request a line-by-line scope of supply. Mark every item as "included," "optional," "buyer supplied," or "excluded."
One of the most overlooked risks in aluminum extrusion equipment procurement is not the main press—it is the interface tolerance between the press, die slide, runout table, puller, cooling system, and downstream handling equipment.
A supplier may build an excellent press, while the auxiliary equipment is supplied by another company with different engineering assumptions. If the runout table height, puller centerline, cooling-bed elevation, or control logic is not coordinated, the line may produce twisted profiles, scratches, unstable pulling, or unnecessary operator intervention.
Before production begins, ask the supplier to provide a full line centerline drawing showing:
- Press exit centerline.
- Die-slide and bolster dimensions.
- Runout-table elevation.
- Puller travel path.
- Cooling-bed height.
- Stretcher loading point.
- Saw location.
- Material flow direction.
- Operator safety zones.
- Electrical and hydraulic interfaces.
This drawing is often more valuable than a generic product brochure because it reveals whether the supplier understands complete-line integration.
Start with the profiles you intend to produce, not only the press tonnage you think you need. Provide profile drawings, alloy grades, billet sizes, annual output, expected extrusion ratio, surface-finish requirements, and downstream-processing requirements.
Ask at least three suppliers to quote using the same technical specification. Compare:
- Press structure.
- Extrusion force.
- Container size.
- Hydraulic circuit.
- Electrical control brands.
- Auxiliary equipment.
- Delivery schedule.
- Installation scope.
- Warranty.
- Spare-parts package.
- Reference projects.
A lower machine price may become expensive if it excludes commissioning, critical spares, automation, or engineering support.
For larger orders, conduct an on-site audit or appoint an independent inspection company. Focus on evidence, not presentation materials.
Check:
- Business registration and legal company name.
- Factory address and ownership or lease status.
- Manufacturing equipment.
- Quality-management records.
- Existing customer projects.
- Export packing capability.
- Service engineers.
- Spare-parts inventory.
- Financial stability where possible.
Do not accept a certificate image without verification. Confirm:
- Certificate number.
- Issuing certification body.
- Validity period.
- Scope of certification.
- Factory name and address.
- Whether the certificate covers the actual manufacturing entity.
For ISO 9001, buyers should verify that the certification is current and issued by a recognized certification body. If an overseas project requires CE-related documentation, include the required documents in the purchase contract before production starts.
The factory acceptance test should be defined in writing. Depending on project scope, it may include:
- Mechanical movement checks.
- Hydraulic pressure tests.
- Safety-interlock tests.
- Electrical-control verification.
- Empty-cycle testing.
- Temperature-control tests.
- Alignment checks.
- Test extrusion where practical.
- Review of drawings, manuals, spare-parts lists, and maintenance plans.
Do not rely only on photographs. Ask for dated videos, measured test records, and signed inspection documents.
Extrusion presses are heavy industrial assets. Buyers must confirm shipping dimensions, container loading plans, break-bulk requirements, lifting points, foundation drawings, and local crane capacity before shipment.
Key logistics questions include:
- Is the shipment containerized or break-bulk?
- Are hydraulic cylinders, electrical cabinets, and control panels packed separately?
- What corrosion protection is used for sea freight?
- Are lifting instructions included?
- Who is responsible for customs documentation?
- What is the expected installation sequence?
- Are technicians available for overseas commissioning?
- What visas, site access, tools, and local labor are required?
China offers a broad range of aluminum extrusion equipment suppliers, from heavy-industry groups to specialized press manufacturers and flexible line integrators. The right choice depends on your product mix, production target, alloy requirements, automation level, budget, and service expectations.
For buyers who need a customized aluminum extrusion press solution with practical communication, flexible project support, and a focus on cost-performance, Foshan Sailixin Machinery Manufacturing Co., Ltd. is a supplier worth including in the shortlist. Its 700T–7,500T press range, 15 years of specialization, reported 1,400+ domestic and overseas installations, dedicated industrial park, and complete-line planning support make it relevant for both new extrusion projects and capacity-upgrade programs.
Before placing an order, request a tailored technical proposal, compare like-for-like equipment scopes, verify certifications, inspect the manufacturing process, and define acceptance criteria in the contract. A detailed specification and transparent factory evaluation will do more to protect your investment than choosing a supplier based on the lowest quotation alone.
For a customized aluminum extrusion press, complete production-line layout, or technical consultation for your aluminum profile project, contact Foshan Sailixin Machinery Manufacturing Co., Ltd. with your profile drawings, billet specifications, expected output, and destination-country requirements.
Ask for the certificate number, certification-body name, issue date, expiry date, and certification scope. Then contact the issuing certification body or search its public certificate database if available. The factory name and address should match the legal entity shown on the sales contract and business registration. A valid certificate should also cover relevant activities such as machinery manufacturing, not an unrelated scope.
You should provide billet diameter, alloy grade, profile cross-section, wall thickness, extrusion ratio, maximum circumscribed-circle diameter, desired output, hollow-profile proportion, and target extrusion speed. A supplier should calculate tonnage based on actual process requirements rather than recommend a model only from rough annual capacity.
No. Oversizing can increase investment, energy consumption, tooling costs, and operating complexity. A press should be selected to provide sufficient force and process stability for the intended profile mix while maintaining efficient cycle times. The best choice depends on your billet size, alloy range, profile geometry, and production plan.
A practical initial package should typically include critical seals, filters, pressure sensors, proximity switches, relays, fuses, hoses, connectors, pump-related service parts, valves or valve-service kits, and important PLC or HMI backup files. The final list should be based on the equipment's bill of materials and the expected lead time for each component.
Evaluate how the supplier responds to detailed technical questions. A capable OEM supplier should be able to revise layouts, adjust container dimensions, recommend auxiliary equipment, explain hydraulic and electrical configurations, provide engineering drawings, and clarify responsibility for commissioning. If a supplier only sends a standard catalog without addressing your profile data and plant constraints, its customization capability may be limited.
