Core Applications

Electric Vehicle Powertrain: Electric motor housings, gearbox components, and drive-system enclosures designed for optimal heat dissipation and structural stability.

Transmission & Drivetrain: Transmission housings and covers integrating bearing seats, oil passages, and mounting points to minimize assembly steps.

Thermal Management: Pump bodies, valve bodies, and coolant housings requiring strict internal pressure tightness and helium/air leak testing.

Automotive Electronics: Enclosures for inverters, controllers, and sensors featuring integrated connector openings and grounding points.

Chassis & Structural Brackets: Multi-functional mounting brackets optimized for high mechanical loads and precise dimensional datums.

Comprehensive Manufacturing Workflow

Engineering & DFM Review: Thorough evaluation of wall thickness, draft angles, parting lines, gating, overflow points, and machining allowances before tooling creation.

Tooling Design & Development: Simulation-driven die design optimized for metal flow, thermal management, shrinkage allowance, and fixture location for downstream CNC machining.

High-Pressure Die Casting: Automated injection of molten aluminum under controlled parameters to ensure microstructural integrity, minimal porosity, and high dimensional repeatability.

Trimming & Deburring: Removal of gates, runners, overflow material, and flash using custom trim dies and precision deburring techniques.

CNC Machining: Multi-axis milling, boring, and tapping for critical sealing faces, bearing locations, and precision holes.

Surface Treatment & Finishing: Shot blasting, chemical conversion coating, powder coating, or anodizing according to corrosion resistance specs.

Quality Control & Testing: Dimensional inspection via CMM, X-ray internal defect analysis, pressure leak testing, and complete PPAP documentation package generation.

FAQ

Q: Can you manufacture parts directly from our existing 2D drawings and 3D CAD models?

A: Yes. Production is developed directly from customer engineering data. A comprehensive technical review is conducted to evaluate draft angles, wall thickness, parting lines, and machining allowances prior to tooling release.

Q: Which aluminum alloys are most commonly used for automotive components?

A: Standard automotive die casting grades include ADC12, A380, and AlSi9Cu3. Material selection is tailored to meet specific mechanical strength, thermal conductivity, corrosion resistance, and pressure-tightness requirements.

Q: How is internal porosity controlled in critical structural parts?

A: Porosity is minimized through advanced filling simulation during DFM, precise die temperature control, optimized gating/venting design, and vacuum-assisted die casting parameters. For high-risk components, non-destructive X-ray inspection can be implemented.

Q: Are leak testing services available for fluid and thermal management parts?

A: Yes. Pressure testing (air-under-water or dry air mass flow testing) can be integrated into the production route for pump bodies, valve bodies, and coolant housings to verify pressure tightness against customer-specified thresholds.

Q: What documentation is provided for automotive project validation?

A: Projects are fully supported with IATF 16949-compliant documentation, including dimensional inspection reports, material certificates, process flow diagrams, PFMEA, Control Plans, capability studies, and full PPAP packages upon request.
