How to Compare CNC Machining, Stamping and Welding for Custom Metal Parts
A sourcing guide to choosing CNC machining, metal stamping, welding fabrication or combined manufacturing routes for custom metal components.
For project-specific review, compare the CNC machining capability, metal stamping capability and welding fabrication capability, then send drawings for an RFQ review.
Use CNC machining for precision features
CNC machining is suitable for tight tolerances, complex holes, threads, slots, mating faces, shafts, bushings and low-to-medium volume precision parts.
Use stamping and forming for repeat sheet metal parts
Stamping, punching, blanking and bending are useful for brackets, plates, clips, covers and repeat sheet metal components.
Use welding for frames and structural assemblies
Welding and fabrication are used when parts need joined structures, supports, braces, frames or load-bearing assemblies.
Many projects combine processes
A single OEM part program may combine cutting, stamping, machining, welding, surface treatment, assembly and inspection before export.
Buyer Questions
Which process is cheapest?+
It depends on geometry, tolerance, quantity, material and finish. The best route should be reviewed from drawings.
Can one supplier manage combined processes?+
Yes. Feiyu can coordinate machining, stamping, welding, finishing, assembly and inspection for custom metal parts.
When should buyers request DFM review?+
DFM review is useful before tooling, high-volume orders or tight tolerance production begins.
