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
Useful for low-friction rings, bushings, rollers, and protective sleeves.
Explore CNC turning →Surface Finishes
Functional as-machined surfaces are typical; edge quality and flatness should be defined around assembly needs.
Discuss finish requirements →DESIGN GUIDE
Designing Parts in PE (Polyethylene)
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 ReviewExpect material movement
Avoid over-constraining large flat parts with unrealistic tolerances.
Support long features
Add thickness or ribs where stiffness is required.
Use practical clearances
Allow for thermal movement and flexible assembly behavior.
Specify grade clearly
HDPE and UHMW-PE have different wear, stiffness, and machining behavior.
