Precision sand tooling from KPMC is designed and built with the latest in tooling technology and automation to assure the dimensional tolerances needed to allow robotic assembly of the mold packages. We provide innovative precision sand tooling for a range of sand casting processes including no bake, blown core, gravity and more for automotive, truck, racing military, marine, and aerospace manufacturers. Our specialties include sand tooling solutions for casting cylinder heads, cylinder blocks, military land vehicle gear boxes, suspension components, marine proto castings, helicopter gear boxes, air frame components and other highly engineered castings—as well as iron castings in automated cells. Our sand tooling solutions assure the highest aluminum to sand ratios and lowest scrap rates. We help develop efficient gating systems using casting solidification modeling to simulate solidification characteristics—identifying possible problem areas of complex components before the casting tooling is designed and built—shortening lead times, reducing costs, producing higher quality castings, and improving yields.

About Sand Casting

In the sand casting process, a sand mixture is packed around a master pattern, forming a mold cavity. The sand mixture is tamped down as it is added around the pattern. The pattern is removed leaving the mold cavity and molten metal is poured into the mold cavity. After the metal has solidified and cooled, the casting is separated from the sand mold. There is typically no mold release agent, and the mold is generally destroyed in the removal process.
