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 conductive pins, terminals, sleeves, electrodes, and rotational electrical components.

Designing Parts in Copper
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 ReviewProtect contact areas
Clearly identify surfaces that must remain clean, flat, or coating-free.
Control thin tabs
Support narrow conductive features to reduce bending during machining.
Plan burr direction
Call out edges that affect assembly, sealing, or electrical contact.
Match alloy to machining
Select free-machining copper where conductivity and production needs allow.
