We are a Sino-American joint venture with unique lost foam casting materials that simplified as STMMA copolymer resin which had been granted American patents. We also have another production line for Hydrogen silicone oil in the manufacturing base.

For the lost foam casting process, the making of foamed mold is very important link. To choose The suitable raw material for your foam-pattern mold making will decide the quality of your Castings.

We specially produce STMMA copolymer resin beads for pattern making in lost foam Casting(white side, foam mould), it has the below advantages compares with EPS: Reduces Carbon defects in castings, reduces carurization defects on the surface of steel/ductile iron Castings, reduces smoke carbon, improves surface finish of castings, reduce the production Costs.
