Insulating Components
Custom Plastic Insulators
CNC machined insulating components made from PEEK, PEI, PTFE, PPS, POM and other engineering plastics for semiconductor, electronics, automation and laboratory equipment.
Material Behavior
Why Engineering Plastics Are Used for Insulating Components
Engineering plastics are often used for insulating components when a part needs electrical insulation together with mechanical strength, thermal resistance, chemical resistance, lower weight than metal, and design flexibility for custom geometry. CNC machining also allows slots, holes, sleeves, shoulders, threads, and mating features to be produced from customer drawings.
Material selection depends on operating temperature, voltage environment, mechanical load, chemical exposure, dimensional tolerance, and part geometry. For demanding equipment, Micrylix reviews the drawing and working conditions before recommending a suitable material from the engineering plastics material range.

Often reviewed for electrical insulation, heat resistance, and rigid equipment components where the grade fits the application.
Useful for chemical resistance, low friction, sleeves, bushings, and spacers, with tolerance planning based on material behavior.
Selected for chemical and thermal resistance in selected equipment environments where dimensional stability is important.
A practical option for cost-effective precision fixtures, positioning components, guides, and insulating support parts.
Machining Review
CNC Machining Considerations
Plastic insulating components can include thin walls, small holes, threaded features, counterbores, shoulders, and mating surfaces. Machining strategy should consider material movement, burr formation, clamping pressure, and repeatability before production.
- Thin wall deformation and clamping force should be reviewed before machining.
- Burr control is important around holes, slots, pockets, and sleeve features.
- Hole tolerance, thread fit, and counterbore depth should be defined clearly on drawings.
- Sharp corner avoidance and suitable radii can reduce local stress concentration.
- Surface finish and small-batch repeatability should match the assembly requirement.
