The Castchem STMMA Formulation VS EPS for Lost Foam

*CastChem developed 20 years ago an advanced casting formulation STMMA for Lost Foam, and it had been granted an American patent.

*CastChem developed STMMA-FD formulation in 2016, specially used for aluminum lost foam cast, also with a relatively low price that easy to be accepted by the foundries.

*CastChem's STMMA sheet contains less carbon molecules than EPS, so it can reduce or eliminate fold defects and excessive lustrous carbon in castings which has been proved by our users in China and American such as BMW,Changcheng automobile and China Railway Construction.

Lost Foam Advantages vs Traditional Casting
*Lost Foam Casting is particularly used for very complex casting. This process eliminates cores and parting lines.
*Lost Foam also improves accuracy in sizing, Casting walls can be curved or of variable thickness.
*Lost Foam casting is cost effective because it does not need as much machining as traditional casting.

Customer can choose STMMA-FD sheets to transfer EPS foam block for lost foam casting.
