PROCESS PLANNING
Machining & Finish
RapidMfgPro reviews geometry, tolerance, material behavior, finish, quantity, and inspection requirements before matching the project with suitable manufacturing resources.
CNC Turning
Excellent for bushings, rollers, rings, sleeves, and precision low-friction parts.
Explore CNC turning →Surface Finishes
Most components are used as-machined because the material can produce a clean functional surface.

Designing Parts in POM (Acetal)
Use the following points as an early DFM checklist. Final recommendations depend on part geometry, stock form, quantity, finish, and functional requirements.
Request a DFM ReviewAvoid excessive press fit
Use realistic interference and account for plastic creep.
Support thin walls
Prevent local flex during finishing cuts and inspection.
Use clear datums
Define functional interfaces and bearing fits from stable references.
Review moisture and temperature
Match tolerance planning to the actual service environment.
