What is Low Pressure Die Casting / Low Pressure Permanent Mold Casting?

Low pressure die casting (LPDC) is a relatively newer process in which metal enters into a die (usually of steel, SG iron, Cast iron) in a very controlled and turbulence free manner.

An air tight furnace is kept underneath the metallic mold, and under air pressure (upto 25 psi - depending on the size of the casting)

The liquid metal rises up from the furnace into the metallic die on top of the furnace.

A very good control of the molten metal is achieved in this process since the speed of filling of the mould cavity is controlled resulting in reliable, pressure tight and homogenous parts.
Experimentally produced pars also show increased mechanical properties compared to other 
processes.

Various critical components in the industry are made through this process for eg: Engine blocks of automobiles,

Cylinder heads, alloy wheels, critical electrical components, special purpose pressure tight parts to name a few.
