Processing PTFE and PTFE Compounds - Powder to Machined Component


The process for making a machined or fabricated part from a PTFE powder (virgin or filled) such as Dyneon®, Teflon® or Fluon® is unique to the plastics process industry and requires very specific manufacturing skills. In summary, there are two steps:


  • 1st Step: Manufacturing a semi-finished stock shape from the raw-powder (batch manufacture using cold pressing and then sintering at high temperature to make a billet; a continuous extrusion process to make longer lengths)
  • 2nd Step: Machining / fabricating the semi-finished stock shape in to the finished part.

When selecting a supplier for your parts, it is important to ensure that the manufacturer has complete control over their source of raw material, from powder through to component.

Fibracon and Insoll have both processing facilities - we process PTFE powders to make our own semi-finished materials (billets) and we source stock-shapes (extrusion) from high quality suppliers. This means that we have complete control of our manufacturing process ensuring:


  • That parts are made to the material specified on the drawing i.e. whether the drawing specifies "Hostaflon® TF4105" or PTFE made to ISO 12086", we will manufacture to that specification.
  • Only the best quality grades from the best suppliers of PTFE are used
  • We have relationships with the raw material suppliers who keep us informed about the market and provide valuable resource when developing new products with customers.
  • There is full traceability for any part that we manufacture.
  • That the optimum size of stock shape is used which ensures we minimise waste material.
 

With our extensive experience in processing PTFE our customers know that they are dealing not only with an expert in this specialized field, but with a company who has complete control of their supply chain.
