What is the primary advantage of Lost Foam EPS?

It allows for the casting of highly complex metal parts with fewer machining steps and significant reductions in material waste.

Does the foam leave residue in the metal casting?

Epsilyte’s Lost Foam grades are engineered to vaporize cleanly, minimizing carbon residue and ensuring high-quality metal surfaces.

What types of metal are typically cast using Lost Foam?

It is commonly used for aluminum, iron, and steel castings, particularly in the automotive and heavy machinery industries.

Is dimensional stability consistent with this grade?

Yes, our Lost Foam beads are manufactured for tight density control and consistent expansion to ensure net-shape precision.

Does this process reduce environmental impact?

Yes, by eliminating the need for chemical sand binders and reducing the weight of final metal parts, Lost Foam is a more efficient casting method.
