Material Category Guide
Engineering plastics are selected for weight reduction, insulation, chemical resistance, low friction, clarity, and temperature performance. Use this page to compare material choices before deciding the final CNC milling, turning, surface finishing, and inspection route.
| Selection Factor | What to Confirm Before Quoting |
|---|---|
| Part function | Load, sliding contact, sealing, electrical insulation, heat exposure, cosmetic needs, and expected life. |
| Machining process | 3-axis, 4-axis, 5-axis milling, turning, Swiss-type machining, drilling, tapping, boring, or reaming. |
| Dimensional control | Critical tolerances, datum structure, wall thickness, flatness, true position, and inspection access. |
| Finishing | Anodizing, plating, passivation, polishing, coating, deburring, or other treatments that may affect final size. |
Material FAQ
Start with the part function, load, temperature, corrosion or chemical exposure, tolerance, surface finish, and target cost. Then compare the material's machinability and inspection risk.
Yes. Harder, tougher, abrasive, or heat-sensitive materials often require slower cutting, more careful fixturing, special tooling, and additional inspection.
Yes. Send the application, drawings, material preference, quantity, and finish requirements. We can suggest practical options before quoting.
Yes. Anodizing, plating, polishing, passivation, coating, and deburring can affect dimensions, cosmetics, and inspection acceptance.
