Expanded Polystyrene (EPS) by Plasti-Fab can be cut by following a patterned drawing. By using this technology the options are astounding.

We can cut up to an 8 foot length of part while cutting multiple pieces at once, thereby reducing material and time.

We also offers engineering assistance at no additional cost. Some of our past projects that we have created with these machines are; signs, logos, circles, steps, display items, snowflakes, pillars, moldings, corners, 2-D/3-D, packaging, prom decor, unusual shapes or liners and so much more.

Specialty Cut EPS is amazingly strong and versatile while providing cushioning, protection and remaining environmentally safe. Specialty Cut Foam at Plasti-Fab lets you achieve product designs that wouldn't be possible with other materials.
