What Is High Pressure Die Casting ?
High Pressure Die Casting (HPDC) is a highly efficient manufacturing process used to produce complex, high-precision metal parts by injecting molten metal into a permanent steel mold (die) at extremely high velocities and under intense pressure. This process is particularly renowned for its ability to create components with thin walls, intricate details, and superior surface finishes that require minimal post-machining.
How High Pressure Die Casting Works
High pressure die casting (HPDC) is a manufacturing process where molten metal is injected into a steel mold (die) at high velocities and under substantial pressure. The process consists of four main stages:
Preparation: Coating the die with lubricant.
Injection: Molten metal is forced into the die at pressures ranging from 1,500 to 25,000 psi.
Cooling: The metal solidifies rapidly within the mold.
Ejection: The finished casting is removed, ready for trimming.
This high-speed process is ideal for creating parts with tight tolerances and smooth surfaces, significantly reducing the need for secondary machining.

Frequently Asked Questions
We primarily work with Aluminum, Zinc, and Copper alloys. While aluminum is the most common for its lightweight properties, our specialized copper high pressure die casting is ideal for components requiring superior electrical and thermal conductivity.
With our range of machinery from 160T to 2500T, we can produce parts from just a few grams up to large-scale components. Our 2500T machine allows us to manufacture substantial structural parts for the automotive and telecommunications industries.
High pressure die casting is a high-speed process that supports rapid cycle times. This efficiency, combined with our automated production lines, significantly lowers the unit cost for high-volume orders and reduces the need for expensive secondary machining.
Yes. Our HPDC process can achieve near-net-shape results with tolerances as tight as ±0.1mm. For mission-critical dimensions, we integrate precision CNC machining as a secondary process to meet your exact engineering specifications.
We utilize mold flow analysis during the design phase to predict and minimize air entrapment. Furthermore, our quality control includes X-ray flaw detection to inspect for internal porosity and ensure every part is pressure-tight and structurally sound.
Absolutely. We offer a "one-stop" solution that includes shot blasting, powder coating, electroplating, and passivation. These finishes not only improve the aesthetic appeal of the parts but also enhance their corrosion resistance in harsh environments.
