Low Pressure Casting

Compared to traditional gravity casting (where molten metal flows into the mold solely under the influence of gravity), Low Pressure Casting (LPDC) offers greater control over the filling process.

It also offers advantages over permanent mold casting, enabling more complex designs and higher-quality surface finishes. Low Pressure Casting (LPDC) is widely used in industries such as automotive, aerospace, and consumer electronics for its ability to produce lightweight, durable parts.
