Recommendations for minimizing wear in the tools Highly glass-loaded thermoplastics can cause significant wear on tools and equipment. Fiberglass has a Mohs hardness of 7. Where possible machine parts and tools that are exposed to Polytron should be hardened. Further, molds should be polished to a 0.0001 (or better) finish High wear is often seen at the gates. If possible; a hardened insert can help in this high wear area For long production molds, a Rockwell hardness of +60 is recommended. This can be obtained by using D2 or A2 steel andthen hardening. Shorter runs can be effectively managed by placing the molds with electroless nickel, slow deposition dense chrome or Nye-carb plating Different long fiber enhance polymer has the same process,but the specific needs also to the actual production process encountered in the specific analysis and solution
