01Die-Casting Molds
Precision mold development, from DFM review and mold-flow simulation to machining, mold trials and sample approval. CNC machining centers, EDM, wire EDM and polishing support the tooling route.
View service
02Zinc Alloy Die Casting
Custom zinc alloy components made to your drawing. Hot-chamber die-casting resources are coordinated with machining, surface treatment and inspection requirements for the finished part.
View service
03Aluminum Alloy Die Casting
Cold-chamber high-pressure die casting for custom aluminum components. Process planning addresses thin walls, housings and precision assembly features, with vacuum assistance considered where the part requires it.
View service
04Magnesium Alloy Die Casting
Custom magnesium alloy castings through dedicated partner production resources. The alloy, part geometry, secondary machining and surface protection requirements guide the agreed manufacturing route.
View service
05CNC Machining
Precision milling, turning, drilling and tapping for critical dimensions, mating features and threads. Machining follows the approved drawing, datum scheme and geometric dimensioning and tolerancing (GD&T) requirements.
View service
06Surface Treatment
Deburring, polishing and blasting prepare the surface. Plating, painting, powder coating, anodizing, passivation and brushing are reviewed for compatibility with the alloy and the required appearance or protection.

07Small-Batch Sample Production
We accept orders to manufacture small quantities of samples to your drawings, material specifications and required quantity. The production route, tooling needs and sample acceptance criteria are agreed before work begins.

Every stage.
Clearly connected.
Tooling, production and acceptance decisions stay connected through one coordinated workflow. Sample orders and repeat production are planned around the agreed scope.
- 01
Review
Drawing, alloy, quantity and critical requirements. DFM and the manufacturing route are reviewed before commitment.
- 02
Develop
Mold design, tooling manufacture and trial samples. Approval criteria guide any agreed corrections.
- 03
Produce
Alloy die casting, deburring, CNC machining and surface treatment follow the approved process.
- 04
Verify
Dimensional and material checks, agreed performance tests and project documentation support acceptance.
- 05
Deliver
Packing, pre-shipment inspection, export documentation and shipment are coordinated to the order.
Defined requirements.
Documented checks.
Partner quality-control processes follow ISO 9001 principles. Inspection and testing are selected for the component and the agreed acceptance requirements.
Explore quality documentation ↗Dimensions & materials
Full dimensional inspection, CMM and optical measurements, alloy composition analysis and hardness testing.
Finish & performance
Salt-spray, color consistency and high/low-temperature testing, where required by the specification.
Project records
Material certificates, dimensional reports, first article inspection (FAI) documents and agreed RoHS/REACH reports.
SGS testing can be coordinated within the agreed scope. Automotive projects can include IATF 16949 quality-system requirements and PPAP Level 3 submissions. Applicable partner qualifications and document availability are confirmed before commitment.
View inspection equipment ↗A clear start.
OEM/ODM and drawing-based projects are reviewed individually. We also consider processing customer-supplied materials, subject to technical assessment.
Can you manufacture small quantities of samples?
Yes. We accept small-batch sample production requests based on your drawing, material specifications and required quantity. Tooling needs, feasibility and acceptance criteria are reviewed for each request. Explore small-batch sample production.
What should I send for a quotation?
Send your drawing and revision, specified alloy, required quantity, critical dimensions, finish and delivery requirements. Include any inspection or documentation requirements. If a specification is still open, tell us so it can be reviewed.
Can we verify the manufacturing resources?
Video factory tours, on-site factory audits and pre-shipment inspections can be arranged with the relevant partner. Learn about our partner manufacturing network.
