What Is High Pressure Die Casting?

High pressure die casting involves the injection of molten metal, under enormous pressure, into the hollow cavity of a custom-made steel forming die. It’s the fastest and most cost-effective way to produce medium to high volumes of metal parts with excellent surface finish and dimensional accuracy.

Advantages Of High Pressure Die Casting

  • Works with aluminum, zinc and magnesium
  • Mold tools can make tens of thousands of parts economically
  • Surface finish and accuracy are excellent
  • Complex geometries can be achieved
  • Especially suited for larger metal parts

The High Pressure Die Casting Process

The success of your high pressure die casting project depends on the quality of the mold tools, and our tool making abilities are unmatched in Asia. After we receive your order, we will:

  • Perform a complete Design for Manufacturing review of your CAD files.
  • Verify tooling and product raw materials for compliance.
  • Use our multi-axis imported CNC machine tools to fabricate the core and cavity.
  • Apply careful heat treating to temper the molds.
  • Exercise process control when casting your parts.
  • Provide any necessary post-machining or processing.
  • Professionally inspect and measure finished parts to meet and exceed your specifications.

High Pressure Die Casting Tolerances

We follow the standard NADCA tolerances for high pressure die cast parts. However, if your requirements are very precise, additional post-process machining can help you to achieve your tolerances.

High Pressure Die Casting Materials

Mold Tools

Our mold tools are usually made from H13 tool steel with a Rockwell hardness of 42-48. Specialty steels are available upon request.

Die Cast Parts

We provide high pressure die casting in several different alloys of aluminum, zinc, and magnesium. Your choice of materials may depend on cost, weight and performance. Here are some tips:

Aluminum is ideal for strong, lighweight yet complex geometries. It can also be highly polished. Our alloys include ADC12, A380, ADC10 and A413.

Zinc is the least expensive but is good for plating. Available alloys are Zinc #3 and #5.

Magnesium offers the best strength-to-weight ratio for higher performance applications. We offer magnesium alloy AZ91D.
