Excess distortion caused by high-temperature operations is a real challenge in the production of plastics and film, but PRG’s proprietary hot & 3D grinding technology provides a unique and effective solution.
We’ll carefully examine your rolls, heat them to operating temperature — up to 600° F and then grind them with state-of-the-art accuracy utilizing our exclusive technology. A more precise grind means a more precise nip, resulting in:

PRG is experienced with all types of rolls and roll materials:
