High Precision Alloy Aluminum Die Casting Auto Parts are engineered to meet the stringent performance requirements of modern automotive manufacturing, particularly in electric and hybrid vehicle applications where lightweighting and structural integrity are critical. These components serve as essential elements in powertrain systems (including transmission housings and motor brackets), chassis assemblies (such as control arms and steering knuckles), and electronic enclosures (battery management system casings), contributing to vehicle efficiency, safety, and durability. By utilizing advanced die casting technologies—including vacuum-assisted casting and real-time process monitoring—we produce parts that reduce vehicle weight by up to 40% compared to traditional steel components, directly lowering carbon emissions by an estimated 8-10% per vehicle and improving fuel economy by 5-7%. Our production processes adhere to IATF 16949:2016 standards, ensuring consistent quality across high-volume production runs (up to 1 million units annually) for major automotive OEMs worldwide, including partnerships with leading EV manufacturers .
Our auto parts are primarily manufactured using Aluminum Alloy 383 (ADC12) and A356.2, selected for their optimal balance of castability, strength, and corrosion resistance. Alloy 383 offers excellent fluidity during casting, enabling complex geometries with thin walls (as low as 1.5mm) while maintaining dimensional stability even in high-temperature environments. Its mechanical properties include a tensile strength of 260-275 MPa, yield strength of 125-140 MPa, and elongation of 9-11%, making it ideal for non-load-bearing structural components like instrument panel brackets and door handles . For high-stress applications like suspension parts and wheel hubs, we use A356.2 alloy with T6 heat treatment, which achieves a tensile strength of 295-315 MPa and yield strength of 230-250 MPa through precipitation hardening. This heat treatment also enhances the alloy’s thermal conductivity (150 W/m·K), improving heat dissipation in brake system components . Both alloys are 100% recyclable, with our recycling program diverting 95% of production scrap from landfills, aligning with automotive industry sustainability goals.
Our die casting process achieves dimensional tolerances of ±0.05 mm for general components and ±0.02 mm for critical mating surfaces, ensured by computer-controlled hydraulic presses (up to 4,000 tons) from leading manufacturers like Buhler and Ube, paired with real-time pressure and temperature monitoring systems. This precision eliminates the need for secondary machining in 85% of applications, reducing production costs by 15-20% compared to conventional casting methods . Inline laser scanning systems (with 0.001mm resolution) inspect 100% of parts post-casting, ensuring compliance with design specifications.
The T6 heat treatment applied to high-performance alloys enhances fatigue resistance, allowing parts to withstand 100,000+ cycles of vibration and thermal stress without failure—critical for engine bay components operating at temperatures up to 150°C. FEA (Finite Element Analysis) is used during design to optimize rib placement and wall thickness, reducing weight by 10-15% while maintaining structural rigidity . Impact testing shows these parts can absorb 20 J of energy at -40°C without cracking, meeting cold-climate performance requirements.
All parts undergo chromate conversion coating followed by powder coating (with 80-100μm thickness), passing 500-hour salt spray tests per ASTM B117 standards with less than 5% surface corrosion. This multi-layer protection system resists road salts, industrial pollutants, and humidity, extending component lifespan to 15+ years under normal operating conditions. For coastal regions, we offer optional anodizing treatments that provide additional 300-hour salt spray resistance .
We offer end-to-end customization from design to production. Our engineering team provides DFM (Design for Manufacturability) analysis within 48 hours of receiving 3D CAD models (supporting formats: STEP, IGES, STL), optimizing wall thickness, gating, and cooling channels to reduce production defects by 25%. Prototypes are available in 2-3 weeks using rapid tooling (aluminum or steel), with full production tooling completed in 6-8 weeks for volumes up to 500,000 units/year . Additional services include:
• Material selection consulting for specific load, temperature, or conductivity requirements
• PPAP documentation (Levels 1-5) including PSW (Part Submission Warrant) and dimensional reports
• Laser engraving with QR codes for full part traceability (from raw material to delivery)
• Just-in-time (JIT) delivery with 99.5% on-time rate, supported by global logistics partners
