Compression Molding - PTFE Molding
Erye Offers PTFE Compression Molding Parts to Your Specific Needs!
Polytetrafluoroethylene PTFE compression molding is a manufacturing process that presses PTFE powder into a mold cavity and sinter the material at elevated temperatures to create the desired shape. Teflon™ PTFE is a thermoplastic resin that has a high melting point. As injection molding cannot effectively process it unique flow characteristics, compression molding has become the popular method for PTFE molded parts.
PTFE material is know for its lwo friction, high thermal stability, outstanding chemical resitant, and it can withstand extreme temperatures (-200°C to 260°C). For all these reasons make PTFE is widely used in demanding applications where conventional plastics fall short.- PTFE molded parts design
- In-house compression molding tooling
- PTFE automatic compression molding for high-volume production
- Secondary processing such as finishing, assembly and custom packaging
Enhance PTFE Molding with Fillers
By blending the PTFE material with other fillers, the unique compounds can exhibit better physical properties. Selecting the right filler or combination of fillers can enhance PTFE properties such as wear resistance, compressive strength, electrical conductivity, and dimensional stability. We offer a wide range of filled PTFE compounds, including:
- Glass fiber
- Carbon
- Graphite
- Bronze
- Colorant
Our PTFE Compression Molding Process
- Material Preparation: PTFE powder is measured and formed into a preliminary shape.
- Mold Loading: The formed PTFE is placed into a heated mold.
- Compression: High pressure compacts the PTFE, causing the particles to bond.
- Sintering: The mold is heated to fuse the PTFE into a solid part.
- Cooling: The part solidifies in the cooled mold.
- Ejection and Finishing: The part is removed and finished.
