Our tooling includes solutions for aluminum and magnesium castings for complex high performance products used in automotive, truck, heavy equipment, construction, military, aerospace, beverage equipment and other advanced manufacturing industries.

 

ABOUT PERMANENT MOLD CASTING

Permanent mold casting molds are preheated and thermal temperatures are maintained as molten aluminum and magnesium alloys are poured over patterns to shape the product. Once the mold is set, the pattern is drawn out to reveal the coarse mold cavity to be machined and made smooth. In the gravity permanent mold process, metal flows using the force of gravity by either static pouring (from the top) or tilted pouring using a basin with the mold on a slant. 

Gravity permanent molds produce more accurate castings than shell mold castings. In the low-pressure permanent mold process, low-pressure forces push metal into the mold. Low-pressure permanent molds produce uniform castings with excellent dimensional accuracy, perfect surface finish and superior mechanical properties.
