Glass Master™ High Performance Feedscrews

Glass Master™ I

Services for Plastics, Inc.’s proprietary tool steel that has been formulated for high wear conditions where cost is still a significant factor. This tool steel has the ability to process high loads of carbon and glass fiber reinforcement over a life-time that exceeds all 4140, H-13, D-2 and Cru-Wear tool steels. There is no feedscrew on the market that provides so much performance for so little money.

Glass Master™ II

Another of SFP’s proprietary tool steel formulations that includes surface treatments to create a feedscrew that will withstand almost any application and process. The Glass Master™ II is specifically designed for ultra-high wear applications where glass fiber and fillers exceed 30% of the volume processed.

Glass Master™ III

If you are currently having problems with short life spans of CPM-9V or other high wear steels and surface treatments, Glass Master™ III is your best solution. We're so confident in these feedscrews that SFP carries a three-year prorated warranty* against excessive wear.
