For low volume part production runs or prototyping, CNC-machining a custom part (or product) from polytetrafluoroethylene (PTFE) or tetrafluoroethylene (TFE) is typically the most convenient, cost-effective option.
But what you might not know is that switching to injection-molded PFA can deliver several major, long-term benefits to your production process.
First, let’s look at the materials themselves. Out of all the fluoropolymers, PTFE is known for being highly flexible, chemical resistant and thermally stable. However, unlike PFA, PTFE can’t be injection molded.
