A hot mold is the solution to achieve crystalline Peek Polyetheretherketone parts. Purging PEEK permits a person to observe the color transformation from a translucent one to a hard colored crystalline one. If the PEEK mold is excessively “cold” (i.e. not hot as much as necessary) the parts will enclose that discoloration or fractional translucency, and the excellence of the finish item will be compromised.
The mold, in the majority cases, must be kept between 350°F and 450°F. This is known as the steel temperature and needs oil or cartridge heat to uphold this level. Complex parts may perhaps need enhanced temperature control so oil would be the favored alternative. It is also recommended to make use of thermocouples to confirm and observe the steel temperature.
These molds must be exclusively planned to run high-temp substances with flow of air, finish, undercuts and steel kinds all factored in from the starting.
Insulator plates present in between mold clamp plates and press platen are a must. The favored steel type depends on whether or not the resin makes use of any abrasive filler but should possess least hardness of 52-54.
