PTFE Compression Molding
APT's custom designed PTFE presses produce consistent quality & mechanical properties throughout a resin lot.
APT's dependable Teflon™ PTFE compression molding presses were custom designed for the particular molding characteristics of PTFE resins. Our presses produce high quality preforms that yield finished parts with consistent mechanical properties throughout the material lot. APT then CNC machines PTFE component parts to print specifications from the molded stock.
Our customers with production quantities of CNC machined parts can sometimes benefit from cost savings we obtain through the use of molded nearnet stock shapes when the part geometry is suitable. Nearnet shapes minimize the amount of excess material required to machine the finished part and subsequently reduce machining time. Time & material savings are ultimately compared to the initial cost of tooling to determine a part volume level that justifies a custom tool.
Our automatic PTFE compression molding equipment, with operational ranges from 10 to 300 tons of pressure, provides us with the capability to mold parts from 1/8” thick to *20” long (*utilizing a modified PTFE fusing technique). APT's PTFE compression molding tooling is custom designed in-house.
APT's PTFE (polytetrafluoroethylene) molding processes include:
- Automatic Pre-forming of PTFE Near Net Shapes
- PTFE Automatic Compression Molding:
- Material Blanks & Dimensionally Finished
- “As Molded” Parts
- Multi-Cavity Tools for increased molding efficiency
- Extra Clean PTFE Molding for special applications
- Modified PTFE Fusing Fabrication (Note: This process is different from hot gas welding)
APT's modified PTFE fusing process is best applied to cylindrical forms such as the special cylinders and containers.
