Dies, tooling and tool room
How is a stamping die designed, step by step?
Answer
First-article inspection, PPAP-aligned documentation and transfer to serial production. About the one outsourced step: slow-wire EDM is used selectively for ultra-fine finish or deep-taper details that fast and medium wire machines are not built for. It is handled by a long-term, audited local partner, while die design, machining, assembly, tryout and maintenance stay in-house and bulk heat treatment runs through an audited partner. Inside the tool room The dies that form these parts are designed and built metres away from the presses.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
