Junkosha Injection Moldings

Fluoropolymer Injection Moldings

Injection moldings that use a high-function thermally fused fluoropolymer such as PFA.
We have developed these moldings with advanced molding technology for numerous benefits, including enhanced chemical, electrical, and physical properties.
Used for sensors and medical purposes demanding chemical resistance, cleanliness, and heat durability.


- We can manufacture these moldings to very precise measurements, with a 0.03μm Rz mirror surface and a tolerance range of 0.05mm.
- A space-saving design based on high precision, thin walls, and miniaturization.
- Widely used in sterilization and cleaning due to superb chemical resistance, heat durability, and long life.
- Excellent flame resistance as well as low water absorption and outgassing.
- Low friction coefficient for excellent slippage.
- Excellent biocompatibility due to low dissolution and cleanliness.
- Outstanding adhesion resistance and smoothness to control bacterial outbreaks.
