How does EPS improve the metal casting process?

Using Lost Foam EPS allows for 'net-shape' casting, which eliminates the need for complex sand cores and significantly reduces post-casting machining.

What types of metals are compatible with Epsilyte casting beads?

Our beads are engineered for high-performance use in aluminum, gray iron, and ductile iron castings.

Do your casting beads leave carbon residue?

Epsilyte's foundry grades are specifically formulated to vaporize cleanly, minimizing carbon defects and ensuring superior surface finish.

Is Lost Foam casting more sustainable than traditional methods?

Yes, it reduces material waste, allows for thinner wall sections (reducing part weight), and uses a sand-recycling process that is more eco-friendly.

What industries use Epsilyte metal casting solutions?

Primary industries include automotive (engine blocks/heads), marine, and heavy industrial equipment manufacturing.
