PEEK Injection Molding | Customized PEEK Parts

Overview

Complex polymer components can be injection moulded based on customer drawings or designed in-house by our team to match the requirements of the end-application.

Poly Fluoro offers a fully integrated moulding set-up from part design and mould construction, to product development and bulk production.

Poly Fluoro brings specialised expertise in the areas of PEEK injection moulding as well precision injection moulding for high-performance, high-temperature polymers such as PPS, PVDF, PESU, and Polyimide. Our special purpose machines are designed specifically for the challenge of moulding polymers that regular moulders would be unable to process.

We offer a range of grades, all of which can be customised with fillers and additives to enhance the component’s end-properties. Working with OEMs around the world, we offer high-precision injection moulded parts where the volumes and/or part construction will not suit a machining solution.

Material selection is essential in getting the correct solution for a given application. Poly Fluoro Ltd understands the strengths and limitations of each material and accordingly works with the end-users to narrow in on the most effective option.

Material Name	Main Properties	Notes/Applications	Temperature Range
Virgin PEEK	Excellent chemical resistance and mechanical properties at elevated temperatures High tensile strength and dimensional stability	FDA approved Most effective as a seal, backup ring, V-packing or Chevron seal Used as rotary seals in Nuclear applications	-40°C to 260°C
Carbon filled PEEK	Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.	Low coefficient of friction and suitable for many extremely corrosive applications	-40°C to 260°C
Acetal or Delrin	Displays good resistance to wear and deformation under load Easy to machine; dimensionally very stable	Excellent for valve seat applications Excellent for ferrules, probes and sensors	up to 80°C
PPS or Ryton	Excellent chemical resistance and mechanical properties at elevated temperatures High tensile strength and dimensional stability	Used extensively in pulp and paper manufacturing as it resists chemicals specific to this industry Cost effective alternative to PEEK	-40°C to 220°C
PVDF or Kynar	Excellent chemical resistance High tensile strength and dimensional stability Resistant to creep	Used in chemical industries for linings, fittings, and sleeves Excellent in semi-conductor components	-40°C to 220°C
PA or Nylon	Displays good resistance to wear and offers thermal and electrical insulation in moderate conditions Easy to machine; dimensionally very stable. Inexpensive	Excellent as bobbins, sliding elements, and insulating sheaths PA6, PA66, and PA12 variants - can be filled with glass or PTFE for enhanced properties	up to 80°C
PFA	Superior chemical resistance Self-extinguishing. Retains room temperature stiffness and strength at elevated temperatures Extreme toughness	Heater cables Chemically resistant linings for pumps and pipes etc. that require a higher temperature resistance.	up to 170°C
FEP	Very high impact strength Excellent high frequency electrical properties Good weathering resistance.	Coatings and protective linings Chemical apparatus Wire coverings Glazing film for solar panels.	up to 150°C
