Hard Chromium Plated Cooling Rolls For Plastic Sheet Extrusion Processes
Plastic sheet production requires extensive cooling. As extruded sheets exit the heated chamber and die, the plastic retains most of its heat due to poor thermal conductivity. Double shell heat transfer rolls efficiently draw heat away from the hot plastic sheet. By guiding the sheet in an "S" pattern through three to five chill rolls (horizontal or vertical orientation), the temperature is reduced to optimal levels. The quality of these chill rolls directly impacts sheet thickness, surface texture, and gloss finish.
Custom Plastic Cooling Roll Finishes
Plastic extrusion cooling rolls must provide efficient heat transfer while maintaining structural integrity. They are fabricated with hardened base metal to resist "worm tracking" and other deformation risks during operation.
Roll Technology supplies heat transfer rolls in various sizes with fully customizable surface finishes to meet specific requirements. Industry-standard options include flawless optical mirror finishes (0~1 Ra) and textured surfaces (matte and satin) with varying roughness levels.
