FAQ

Frequently Asked Questions

Find quick answers about engineering plastic CNC machining, material selection, tolerances, and secondary operations.

We commonly machine POM (Delrin), PEEK, Nylon (PA), PTFE, Polycarbonate (PC), UHMW-PE, and other engineering plastics based on project requirements.

It depends on the application. POM offers excellent machinability and dimensional stability, PEEK performs well in high-temperature and chemically demanding environments, while Nylon provides good strength and wear resistance.

Achievable tolerances depend on the material, part geometry, feature size, and environmental stability. Tighter tolerances are available for suitable critical features.

Yes. Thin-wall plastic parts can be machined with appropriate tooling, workholding, and cutting parameters to reduce deformation, vibration, and heat buildup.

Available options include as-machined finishes, polishing, thread inserts, laser marking, and other secondary operations depending on the material and application.

Material certificates and documentation can be provided for selected engineering plastics upon request, subject to supplier availability and project requirements.
