Processing methods for fluoropolymer tubing

Abstract

A method for processing a fluoropolymer tube involves creating a kit connected to the fluoropolymer tube in a thermoforming machine. The method includes: 1. Fabricating a fluoropolymer tube and forming a spiral joint on the fluoropolymer tube; 2. Opening a first mold cavity compatible with the fluoropolymer tube and a second mold cavity for forming the kit on the fluoropolymer tube in a pair of molds of the thermoforming machine; 3. Injecting fluoropolymer raw material into the thermoforming machine and heating it to melt, then placing the fluoropolymer tube into the first mold cavity of the pair of molds, with its joint aligning with the second mold cavity; and 4. Closing the pair of molds, injecting the molten fluoropolymer raw material into the second mold cavity, and opening the pair of molds after cooling to form a kit covering the fluoropolymer tube.
