Stamping Parts Manufacturing Process

Stamping Parts Manufacturing Process

Core Processing Steps

Processing follows the process route. The core processes differ significantly depending on the type of non-standard part:

Sheet Metal Non-standard Parts: Laser cutting (high-precision blanking) → CNC bending (precise angle control) → Welding (argon arc welding/spot welding to ensure weld strength) → Stamping (forming complex structures).

Machined Non-standard Parts: CNC machining (milling, drilling, tapping) → Grinding (high-precision surface treatment) → Heat treatment (quenching/annealing to increase hardness).

In-Process Quality Inspection (IPQC)

First Article Inspection: The first piece must undergo full-dimensional inspection (using calipers, micrometers, projectors, and coordinate measuring machines) to confirm compliance with drawing requirements before mass production.

Routine Inspection: Sampling inspection is conducted during each batch of production to promptly identify dimensional deviations, surface defects, and other issues, preventing batch scrap.

Record Retention: Inspection reports are completed, and inspection data is retained for traceability.
