Move projects forward with physical parts, samples and agreed requirements
Discuss custom production based on structure, materials and quality requirements, with clear processing scope, measurement methods and production arrangements.


Structure and tooling review
Use drawings or samples to define critical dimensions, molding features and tooling needs, then discuss tooling and sampling scope.
Material and molding support
Assess material requirements against temperature, media, hardness and intended use, then plan production for the approved solution.
Dimensions and sample approval
Agree on dimensions, appearance, assembly and required documents. Validate actual function and performance through project-specific tests.
Customization process
Every step has requirements to confirm
- 01
Drawings and application review
Define the structure, critical dimensions, assembly and operating conditions.
- 02
Material and tooling assessment
Discuss solutions and quotation scope based on materials, quantities and acceptance requirements.
- 03
Sampling and assembly approval
Check sample dimensions, appearance and actual fit against agreed requirements.
- 04
Production and delivery planning
Plan quantities, inspection and lead times based on the approved solution.
Questions before working together
Clarify materials, quality and delivery requirements
Can I start without a complete drawing?
Start with the intended use, sample photos, critical dimensions and assembly method, then confirm whether drawings or physical samples are needed.
How are materials and certification documents confirmed?
Specify the use, target market, material grade and required documents. Check each report's product, material and applicable scope.
How are minimum quantities, costs and lead times determined?
Confirm these based on structure, materials, tooling status, estimated quantities and acceptance requirements. A general figure cannot replace a project quotation.
How do we arrange a visit or send samples?
Contact the sales team to confirm the current production location and delivery details before visiting or sending samples. The registered address is not automatically the sample delivery address.
