  • What is high pressure die casting?

High-pressure die casting (HPDC) is a manufacturing process where molten metal, typically aluminum, zinc, or magnesium, is injected at high pressure (10,000–30,000 psi) into a precision-engineered steel mold (die) to produce complex, high-quality parts with tight tolerances. It’s widely used in the lighting industry for components like LED heat sinks, lamp housings, and brackets due to its efficiency, precision, and ability to produce intricate shapes in high volumes.

Limitations:

High Initial Costs: Steel dies are expensive, making HPDC less economical for low volumes.

Material Constraints: Limited to non-ferrous metals like aluminum or zinc.

Porosity: High pressure can trap air, requiring careful process control to minimize defects.
