VICTREX® PEEK™ polymer compression molding products offer differentiated advantages
As a general rule, compression-molded parts are more crystalline, have a higher modulus and tensile strength, are harder yet have a lower ductility and can be more brittle. Milled fibers (glass and carbon) may be compounded into VICTREX PEEK for compression molding, albeit with loss of anisotropy, lower strength, different C.T.E. and tribological properties than injection-molded parts. Very thick sections may be subject to cracking and a post processing thermal treatment (annealing) should be used to relieve stresses.
Close tolerances cannot be achieved directly, therefore components must be machined. The outer and inner surfaces of moldings may be discolored due to the mould release agent and being in contact with the tooling, so these surfaces should be skimmed to remove the discoloration.
Other considerations for VICTREX PEEK compression molding include:
- Mold Pressures
- Mold Temperatures
- Annealing
- Machining
- Drying
- Mold Release Agents
- Oven Requirements
