Step 3: The extrusion process

Through the very high pressure inside of the extruder cylinder, the PTFE virtually plastifies, thus enabling it to be put around the conductor wire with the help of the used tools, which define the wall thickness (and possible shape). Due to the very high pressure (1300 bar) whichis present inside of the extrusion head during operation, it is technically very difficult to maintain the conductor completely centered inside of the insulation. Our PEX extruders are marked by especially high centiricty values!
