What Is Low Pressure Die Casting?

Low pressure die casting is a metal casting process in which molten metal is introduced into a metal mold under controlled low pressure to form the required part shape. It is widely used for producing repeat-order non-ferrous metal components with stable filling, improved consistency, and reliable support for subsequent machining or finishing. The process is commonly applied to housings, covers, pump parts, brackets, and other industrial metal components.

1. Mold Preparation

Metal molds are prepared according to part geometry, application requirements, and production needs to support stable low pressure die casting performance.

2. Filling and Solidification

Molten metal is introduced into the prepared mold under controlled low pressure and allowed to solidify into the required part shape.

3. Trimming and Cleaning

After solidification and demolding, the casting is trimmed and cleaned to remove excess material and prepare the part for the next production stage.

4. Machining and Final Inspection

When required, the casting goes through secondary machining and final inspection to support dimensional consistency, functional requirements, and delivery quality .
