Manufacturers Compression Molding Guide

When molders must form large and intricate parts out of advanced thermoplastics, they are using Victrex Peek, a high performance polymer with more than 30 years of proven success, to compression mold components at lower overall costs for the most demanding oilfield, transportation, electronics, and medical applications. 

As specified in detail in the new eight-page Victrex Compression Molding Guide, this traditional processing method involves using a high heat, high-pressure hydraulic press. Included are descriptions of the requirements for the equipment and tooling with the seven-step process that can deliver void-free moldings. Compression molding Victrex Peek also allows for slower cooling time than injection molding; a key benefit shown in the incorporated graphs that shows higher levels of crystallinity which can improve part performance.

For compression molding, Victrex fine powder grades such as Victrex 150PF, 450PF, and 650PF are readily available as standard grades.
