Plastics and Film Industry

Excess distortion caused by high-temperature operations is a real challenge in the production of plastics and film. PRG’s proprietary hot & 3D grinding technology provides a unique and effective solution for your operation.

Here’s how it works: Rolls are carefully examined, then heated to operating temperature – up to 600° F. Next, the rolls are ground with state-of-the-art accuracy.

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

  • Chilled Cast Iron
  • Chrome Plated
  • Displacement Body
  • Engraved
  • Hardened Steel
  • Peripheral Drilled
  • Polyurethane Covered
  • Rubber Covered
  • Tokuden™
  • Carbide Coated
  • Ceramic Coated


The Result Is In The Roll!

PRG will help your plant extend roll life using our 24-point Spec-Check™. We guarantee tighter tolerances than even OEM specification – up to +/- 20 millionths of an inch and surface finishes of ¼ to ½ micro inch Ra! A more precise grind means a more precise nip:

  • Uniform Pressure
  • Uniform Caliper
  • Uniform Wear Profiles
  • No “Break-In” Requirements
  • Improved Sheet Consistency
  • Longer Between Grinds
  • Better Quality Products
  • Satisfied Customers
