PTFE Molded Tube

Molded PTFE Tubing: High-Density Raw Stock for Precision Machining

Our molded ptfe tubing is specifically engineered as a premium semi-finished material. By utilizing high-pressure compression molding and controlled sintering, we provide a product with exceptional molecular density. This ensures that when you machine this tubing into final parts, the material maintains its structural integrity and dimensional stability.

Technical Specifications for Semi-Finished Tubing

Our Manufacturing Advantage: Controlled Sintering Cycle

Our factory implements a Controlled Sintering Cycle. After reaching the peak sintering temperature, we apply a programmed, gradual cooling phase. This slow temperature reduction helps minimize internal residual stresses, ensuring that the molded ptfe tubing remains stable during secondary turning and milling processes.

Designed for Machining (Bushing & Seal Production)

We provide our tubes with:

1. Generous Machining Allowances: Sufficient material on both inner and outer diameters to ensure a clean finish after machining to your final dimensions.
2. Uniform Structure: Consistent molecular distribution from surface to core, preventing structural defects when machining thin-walled bushings.
3. Custom Sizing: Tailored lengths and wall thicknesses to minimize material waste in your production line.

FAQ - Sourcing Semi-Finished PTFE Tubing

Q: Why use molded ptfe tubing instead of solid rod for bushings?

A: Using tubing as a blank significantly reduces machining time and material scrap, lowering the overall cost of your finished custom rubber product or plastic part.

Q: Can these tubes be used for high-pressure chemical seals?

A: Yes. Due to the high compression ratio during molding, our tubes offer excellent impermeability and chemical resistance.
