Choosing the right equipment, especially the mold, adapted to both production rate and precision is the know-how of all injectors.
Regarding high performance plastics, the process requires but lot of know-how compared to standard plastics. First, due to its high viscosity at molten state, PTFE, the most common fluoropolymer, can’t be injected. It can easily be replaced by other fluoropolymers. PFA, FEP, ETFE can be injected and are good solutions when requiring injected parts. And of course PEEK and PI are injectable high performance polymers too.
Second, and more important, high temperatures involved in melting high performance polymer require specific toolings around the molds. The equipments must be well adapted to the pressure and the production cycles. There, experience in such difficult materials will make all the difference in the quality of the final production.
In association with this high temperature, compounds are also often more abrasive or corrosive and tools require more precise control, and specific technologies requiring special steel implementation.
