Zinc Die Casting of Vehicle Parts

Zinc die casting automotive parts are precision-engineered components manufactured using hot chamber die casting technology. The process is suitable for high-volume automotive production requiring complex geometries, consistent repeatability, and stable mechanical performance.

• DFM engineering review for manufacturability validation
• Mold design and tooling manufacturing
• Hot chamber zinc die casting production under controlled process parameters
• Trimming and deburring
• CNC machining for functional interfaces (if required)
• Surface finishing (plating / coating / chromating)
• Final inspection and validation
• Packaging for export logistics and OEM supply chain

• DFM Engineering Support
• CAD manufacturability evaluation 
• Structural optimization for die casting feasibility 
• Gate and runner system optimization 
• Reduction of unnecessary machining features 

Automotive Design Guidelines
• Uniform wall thickness for stable filling and cooling 
• Draft angles required for mold release efficiency 
• Rib reinforcement instead of excessive material thickness 
• Avoid sharp internal corners to reduce stress concentration 
• Functional surfaces defined for secondary machining when required 

Engineering Decision Rules
• Zinc die casting is ideal for complex small-to-medium automotive components with stable production demand
• Zinc die casting is not recommended for large structural chassis components or high-temperature continuous operating environments
• Recommended wall thickness range: 0.5 mm – 4.0 mm for stable flow and structural integrity
• For continuous operating temperatures exceeding 120°C, an engineering feasibility review is required to evaluate material suitability versus aluminum alloys

Engine & Transmission Systems
• Throttle bodies 
• Valve covers 
• Fuel system interface components 

Safety & Electronic Systems
• ABS sensor housings 
• ECU connector housings 
• Steering column components 

Interior & Exterior Systems
• Door lock and latch mechanisms 
• HVAC system housings 
• Decorative trims and interior functional parts

Quality & Compliance Standards
• ISO 9001 quality management system 
• IATF 16949 automotive quality system 
• RoHS / REACH compliance support 

Process Stability & Traceability
• Full batch traceability from raw material to finished parts 
• Statistical process control (SPC) for production stability 
• Controlled engineering change management system 

Inspection & Testing Capability
• CMM dimensional inspection (Accuracy up to ±0.005 mm)
• X-ray internal defect detection for porosity control
• Hardness and mechanical property testing 
• Visual and surface quality inspection
• Full PPAP Level 3 documentation support available upon request, including FMEA, Control Plan, and MSA
