Stamping Die Components Manufacturer in China

Custom Components for Precision Stamping Dies

Every stamping application has different requirements for wear resistance, toughness, clearance, surface finish and dimensional stability. We manufacture components directly from approved drawings and coordinate machining, heat treatment, grinding, EDM, wire EDM and finishing through one production workflow.

• Cutting punches and forming punches
• Die inserts and cutting blocks
• Forming inserts, bending components and pilots
• Stripper inserts and pressure pads
• Guide components, wear plates and support blocks
• Carbide punches, dies and wear-resistant inserts
• Replacement components for existing production tooling

Processes Matched to Critical Features

Tool Steels, High-Speed Steels and Carbide

We machine a broad range of materials used for precision stamping tooling. Final material selection should reflect part thickness, production volume, wear mechanism, impact load, required edge life and maintenance strategy.

• Tool steels: SKD11, DC53, D2, A2 and related cold-work grades
• Hot-work steels: SKD61, H13 and customer-specified grades
• High-speed steels: M2, M35, M42, SKH-9, ASP23 and ASP60
• Tungsten carbide: KD20, CD650, YG20, K20, K30 and K40

Heat treatment, deep cryogenic treatment, nitriding and PVD coatings can be coordinated according to tooling requirements. Material certificates can be supplied when specified.

Precision for Connector and Electronic Stamping

Small terminals, contacts, shields and connector parts often require stable die clearance, accurate pitch, fine forming geometry and consistent repeatability. SKYPU MOLD supports precision tooling components for connector, electronics, automotive and other high-volume stamping applications.

When reviewing a project, we consider the relationship between component accuracy, heat-treatment movement, grinding allowance, assembly datums and the customer’s inspection method.

Tolerance and Inspection

Tight-tolerance stamping die components require more than a nominal machining capability. The complete process must control material condition, heat treatment, datum strategy, finishing sequence and measurement environment.

• Incoming material verification
• In-process inspection after key operations
• Hardness and dimensional verification after heat treatment
• Final inspection against drawing requirements
• Critical-dimension or full inspection reports upon request
• Material and production traceability

Selected features may be supported down to ±0.001 mm. Feasibility is confirmed after reviewing the complete drawing, material, feature size, geometry and inspection requirements.

Replacement Parts and Tooling Maintenance Support

Downtime caused by a worn or damaged punch, insert or die component can be expensive. We support replacement components from complete drawings and can prioritize urgent production when capacity and material availability allow.

For the fastest review, identify the tool number, component number, material, hardness, coating, critical dimensions and required delivery date. Where a component must match an existing assembly, clearly mark the mating features and inspection datums.

Our Manufacturing Workflow

1. Drawing review: confirm geometry, material, heat treatment, tolerances, surface requirements and quantity.
2. Process planning: define machining sequence, grinding allowance, EDM requirements and inspection stages.
3. Manufacturing: produce the component through the approved machining and finishing processes.
4. Inspection: verify dimensions, hardness and specified quality requirements before shipment.
5. Delivery: protect precision surfaces and cutting edges for reliable international transportation.

Часто задаваемые вопросы

What files do you need to quote stamping die components?

Please provide a 2D drawing or 3D model, material, hardness, coating, quantity, critical tolerances and required delivery date. STEP, IGES, X_T, DWG and PDF files are commonly accepted.

Can you manufacture carbide punches and die inserts?

Yes. We machine selected tungsten carbide grades for punches, die inserts and wear-resistant components. Geometry, grade, surface finish and edge requirements should be clearly specified.

Can you make replacement components for an existing die?

Yes. Complete manufacturing drawings are preferred. Please identify mating dimensions, datums, fits and any features that must match the existing tooling.

Can you achieve ±0.001 mm?

Selected precision features can be supported down to ±0.001 mm, subject to geometry, material, heat treatment, feature size and inspection method. We confirm feasibility during drawing review.

Can you provide inspection reports and material certificates?

Yes. Dimensional inspection reports, hardness records and material certificates can be provided according to the agreed project requirements.
