Carbon and titanium oxide removal of extrusion components

 

We extrude FEP (Teflon) onto wire and cable. We also color coat the wire with titanium oxide. We are getting a build-up of carbon and titanium oxide on the extrusion components: tips, barrels and dies. This requires teardown of the equipment (every 2-3 weeks) with labor intensive abrasive buffer cleaning of the components.

Questions:

1) Are there metallurgical, ceramic, diamond or other coatings that could prevent build up and be hydrogen fluoride resistant - thus reducing the number of times we have to breakdown and clean?

2)Or, are there any effective chemical or other cleaners (cleaning methods) available that would reduce destructive effects of abrasive cleaning and decrease the time required to clean?

Any assistance would be appreciated.

Are you coating your extrusion components with electroless nickel or chromium? You can add diamond, teflon, carbides, oxides,nitrides, silicides, boron zirconium oxides, etc. to electroless nickel deposits.
