Aluminum die casting is a highly efficient manufacturing process that produces precise, complex metal parts with excellent surface quality. At Dongguan Yuhui Die Casting, we specialize in precision aluminum die casting, serving industries such as automotive, aerospace, and telecommunications for over 27 years with an annual production capacity exceeding 10,000 tons of aluminum parts.
Aluminum die casting involves injecting molten aluminum alloy under high pressure into a steel mold to create complex, high-precision components. This process can achieve dimensional tolerances as tight as ±0.1 mm and surface finishes down to Ra0.8μm, enabling mass production of parts with consistent quality.
Learn more about our Die Casting Services where our machines range from 88 to 2000 tons of clamping force, allowing parts up to 1200 mm in length and wall thickness from 2 mm to 20 mm.
Material Preparation
We select aluminum alloys such as ADC12 and A380, known for tensile strength up to 310 MPa and excellent corrosion resistance.
Melting
Our melting furnaces operate at temperatures around 680°C, ensuring optimal alloy fluidity.
Injection
High-pressure injection (up to 200 MPa) into precision molds with cycle times typically between 15-60 seconds, depending on part complexity.
Cooling and Solidification
Rapid cooling minimizes defects; typical solidification times are 5-15 seconds per cycle.
Ejection and Finishing
Our CNC machining center includes 50+ machines with 3 to 5-axis capability, achieving tolerances within ±0.05 mm.
Quality Inspection
Using advanced measuring tools including CMM (Coordinate Measuring Machines), we maintain a product defect rate below 0.5%.
Explore our full Manufacturing Capabilities to see how we optimize each process.
High Precision and Complex Shapes
Achieve tight dimensional accuracy of ±0.1 mm, suitable for structural and functional parts.
High Production Efficiency
With over 20 die casting machines, we prod 20uce up to 1 million parts annually, reducing lead times by up to 40% compared to alternative processes.
Excellent Mechanical Properties
Typical tensile strength for ADC12 aluminum alloy is 240-310 MPa, with lightweight parts reducing vehicle weights by 10-15%.
Eco-friendly and Material Efficient
Over 95% material utilization with recyclable scrap, reducing environmental footprint.
Superior Surface Finish
Surface roughness values as low as Ra0.8μm, cutting down secondary finishing costs by 30%.
