LOW PRESSURE PERMANENT MOLD

What is the low pressure permanent mold casting?

This process automatically or semi automatically supplies liquid metal from a furnace, under pressure, up to 1 atmosphere, to a mold or die. This allows the metal to not only fill the contours of the casting shape but to feed the shrinkage while the solidification of the casting progresses to completion. Compared to the traditional permanent mold process low-pressure permanent mold yields mechanical properties approximately 5% superior. The yield is generally greater and thinner walls can also be produced.

THE CASTING PROPERTIES
Due to the chilling nature of the steel tooling the castings are very sound. This lends the process to parts that need to be pressure tight and that need to have very little porosity.
