Stamping and forming processes
What is the difference between blanking and piercing?
Answer
Deep drawing is a metal forming process that produces seamless, hollow parts—depth exceeds diameter—by pulling material into a die cavity. Progressive stamping is a high-speed process where a coil-fed strip moves through multiple stations, each doing a specific operation like blanking, piercing, or forming, to make flat or contoured parts. The key difference is part depth: deep drawing gives you deep, hollow shapes, while progressive stamping is for shallow or contoured designs. Which process is better for deep, cylindrical parts?

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.
