High-Pressure Die Casting

Aluminum High-Pressure Die Casting (HPDC)

With clamping forces ranging from 80T to 9000T, this process enables the mass production of thin-walled aluminum castings with high dimensional stability.

Process

What is High-Pressure Die Casting (HPDC), and when is it appropriate to use it?

Molten aluminum is injected under high pressure into a hardened steel mold, where it solidifies within seconds. This method is well-suited for complex, thin-walled parts that require high dimensional repeatability and a low per-unit cost.

Gravity Die Casting

Aluminum Gravity Die Casting (GDC)

Tilt-pour and horizontal gravity die casting, used for manufacturing aluminum parts with thick sections, high structural integrity, and pressure-tight properties.

Process

What is gravity die casting, and when is it appropriate to use?

Molten aluminum flows into a reusable metal mold under the force of gravity. The slower filling rate results in castings with higher density and a more stable structure—making this an ideal choice for parts with thicker sections, components requiring high pressure tightness, and projects where lower tooling costs are needed for small-batch production.

Low-Pressure Casting

Aluminum Low-Pressure Casting (LPDC)

Utilizing a process of low-pressure mold filling and pressure-controlled solidification, this method is used to manufacture aluminum alloy components characterized by complex geometries, dense microstructure, high strength, and high structural integrity. It is well-suited for automotive chassis components, suspension systems, subframes, and other high-performance aluminum structural parts.

Process

What is low-pressure casting, and when is it appropriate to use?

In low-pressure casting, molten aluminum is driven by controlled, low-pressure gas to rise steadily from a holding furnace and fill a metal mold, where it then solidifies under sustained pressure. This stable mold-filling process helps minimize defects such as entrapped air, oxide inclusions, and shrinkage cavities, resulting in castings with a dense microstructure and consistent mechanical properties. It is well-suited for aluminum alloy components—such as automotive chassis parts, suspension components, and subframes—that require high strength, airtightness, and structural integrity.

For overseas industrial clients—beyond the automotive sector—key areas to highlight include industrial machinery, pumps and valves, energy equipment, robotics, telecommunications equipment, aerospace, and power equipment. For each manufacturing process, emphasize specific equipment capabilities, the range of machinable alloys, dimensional capacities, quality inspection protocols, and experience with mass production.
