4B Plastics Manufacturers Compression Molded Unfilled and Filled PTFE and Stock a Variety of Other Specialty Thermoplastics

If you want quality parts start with quality stock materials. By molding a lot of our own PTFE stock we can maintain qualtiy control through to the finished parts.
The granular form of the required material is placed in a mold and based on the size a certain “recipe” of pressure and time produces the initial stock material… but we’re not through. The stock is then placed in our industrial ovens and baked to complete the curing of the thermoplastic process.
