Automatic Molding

Automatic molding, a semi-automated form of compression molding, is the process PFI uses for the manufacture of medium-volume to large-volume net molded and near net molded PTFE components. The automatic molding process requires dedicated tooling, typically requires minimal operator intervention and plastic parts can be fabricated relatively rapidly.

With the use of precise tooling and processing, parts manufactured using the automatic molding process can be produced to relatively close tolerances, but not to the accuracy of a fully machined part. Components are economically molded by utilizing a process of automated filling of the die cavity, applying pressure, and part ejection.

Other advantages of the automatic molding process include:

  • Little or no scrap material as compared to the "typical" PTFE machining process from stock shapes (rod or tube)
  • Lower part cost, with minimal or sometimes no machining steps required
  • Components that are molded and sintered into final forms and shapes have reduced stress defects compared to machined parts (from cutting, milling, etc.)

Disadvantages include:

  • Dedicated tooling costs
  • Limited to relatively simple shapes and more open tolerances

The knowledgeable PFI staff can work with you from initial concept, through to design, production and finish. With our expertise in a wide range of plastic materials, PFI can recommend the best plastic resins, plastic compounds and fillers to maximize performance and be cost-effective in your specific application. Contact the PFI staff and see if automatic molding is suitable and economical for your application.
