Save your distorted rolls — and save money — with PRG’s proprietary hot & 3D grinding technology.

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:

  • Uniform pressure
  • Uniform caliper
  • Uniform wear profiles
  • No “break-in” requirements
  • Improved sheet consistency
  • Longer between grinds
  • Better quality products
  • Satisfied customers


Every roll goes through our thorough 24-Point Spec-Check our 24-point Spec-Check™ — so exceptional quality is guaranteed.

We achieve tighter tolerances than even OEM specification — up to +/- 20 millionths of an inch and surface finishes of ¼ to ½ micro inch Ra. And every roll goes through our thorough 24-Point Spec-Check to ensure it meets our high standards for roundness and uniformity.
