Film extrusion of plastics such as PVC poses unique challenges to tools. The corrosive outgassing of the resin attacks the traditionally chrome-plated tools, causing tool failures and production stoppages. Ionbond^™ PVD coatings provide the corrosion resistance to protect and improve tool life. The abrasive wear resistance of Ionbond^™ PVD coatings facilitates the cleaning of the tools after batch or color changes without affecting its surface quality.
