Plastic & Mold Steels
The demands on the molds and wear parts used to process plastics have risen dramatically. The increased use of engineering resins and glass fillers, coupled with more complex designs and performance requirements have led to extensive research and development of the various tool steels and alloys used with these plastics.

More than in any other industry, the steels used in the manufacture of plastics can vary widely from simple, low alloy steels to advanced stainless steels to some of the most sophisticated high performance tool steels available today. As plastics find their way into an ever-broadening range of engineering applications, the use of new resins, additives and fillers demand higher wear and corrosion resistance from the metallic materials used for the molds and tooling required to process them.

Crucible Service Centers has a full range of steels for use in the plastics industry available from our warehouse stock. Included along with many conventional tool and mold steels are highly wear resistant materials made using our proprietary CPM process as well as stainless steels for molds and holder blocks.
