Material Properties & Machining Notes
The points below are for reference only. Final material selection and tolerance planning depend on grade, stock condition, part geometry, and working environment.
Key Properties
CNC Machining Notes
- PEI is machinable but requires heat and chip control.
- Transparent or amber parts may need cosmetic surface review.
- Threads, pockets, and thin walls should be checked before production.
- Tolerance should be matched to part geometry and grade.
Typical Applications
Common applications vary by material grade, tolerance, surface finish, and operating conditions.
