English communication and export-focused service for international buyers.
Customizable Delivery
Tolerances, surface finish, markings, packaging, and inspection docs tailored to your needs.
Design and Milling Considerations for Plastics
Plastics behave differently from metals. Proper design ensures stable performance and efficient machining.
-
Tolerance strategy: Plastics exhibit thermal expansion and creep. Define critical dimensions with realistic tolerances.
-
Feature design: Avoid overly thin walls and sharp internal corners; use radii to reduce stress.
-
Moisture effects: Choose low-moisture-absorption materials (POM, PEI, PEEK) for dimensional stability.
-
Friction and wear: Use UHMW-PE, PTFE, or wear-resistant grades for sliding components.
-
Heat and chemicals: Select high-temperature or chemical-resistant polymers (PEEK, PPS, PVDF) where required.
-
Surface finish: Define cosmetic and functional surface needs; appropriate tooling and feeds deliver required results.
-
Assembly features: Use milled threads, inserts, or tapped holes with allowances for plastic behavior.
We provide recommendations on material, geometry, tolerance, and finish before production.
