In modern automotive, industrial, and electronics manufacturing, aluminum die casting is the premier process for producing lightweight, high-volume, and geometrically complex components. By forcing molten aluminum alloy into precise metal molds under high pressure, high-pressure die casting (HPDC) creates durable parts with exceptional dimensional accuracy, thin wall capabilities, and excellent heat dissipation.
We provide complete aluminum die casting services—integrating mold design, high-tonnage die casting, secondary CNC machining, and specialized surface finishing to deliver mission-critical parts for OEM clients worldwide.
Aluminum alloys offer an outstanding strength-to-weight ratio, making them the material of choice for performance-driven applications. Partnering with us for your aluminum die casting needs provides direct engineering benefits:
High Production Efficiency & Cost-Effectiveness: Fast cycle times make HPDC exceptionally economical for medium-to-high volume production runs.
Complex Thin-Wall Capabilities: Cast intricate geometries with wall thicknesses as thin as 1.5 mm, reducing overall component weight without sacrificing structural strength.
Tight Dimensional Control: Achieve precise dimensional tolerances aligned with ISO 8062 CT3–CT5, minimizing post-casting machining requirements.
Excellent Thermal & Electrical Conductivity: Ideal for heat sinks, motor housings, and electronic enclosures requiring efficient heat dissipation.
Versatile Surface Treatments: As-cast parts easily accept anodizing, powder coating, liquid painting, and shot blasting for enhanced corrosion resistance and aesthetic appeal.
We melt and cast a comprehensive selection of commercial aluminum die casting alloys conforming to global standards (ASTM, EN, JIS):
A380 / ADC10: The most widely used general-purpose alloy, offering an optimal balance of castability, mechanical properties, and thermal conductivity.
A360 / ADC3: Features excellent pressure tightness, superior corrosion resistance, and high fluidity for intricate thin-walled designs.
A383 / ADC12: Provides improved die-filling capacity and resistance to hot cracking, making it ideal for highly complex castings.
AlSi10Mg: Exceptional structural alloy for parts requiring high strength, impact resistance, and good weldability.
