Press Work
Press work forms sheet metal parts at high speed using dies in mechanical or hydraulic presses, including blanking, piercing, forming, drawing and progressive operations. It is the most economical method for high volumes of identical sheet parts.
What it is
A die set mounted in a press cuts or forms the sheet in each stroke. Simple dies do one operation; compound dies combine cutting operations; progressive dies perform several stations in sequence as a coil strip advances, producing finished parts at high rates.
Tooling is an upfront investment, but part cost is very low at volume, with excellent repeatability.
Typical applications
- Washers, clips and brackets
- Automotive and two-wheeler pressings
- Electrical terminals and laminations
- Appliance components
- Hardware and fastening parts
Suitable materials
- CRCA and HR steel
- Spring steel
- Stainless steel
- Brass, copper and aluminium
Points to consider
- Tooling cost is justified at higher volumes; laser cutting suits low volumes.
- Design for pressing: consistent thickness, generous radii, avoid tiny holes.
- Burr direction should be specified for safety or function.
- Tool ownership and maintenance terms should be agreed.
Frequently asked questions
When is press work cheaper than laser cutting?
At higher volumes, typically thousands of parts, where the tooling cost is spread and each stroke makes a part in seconds.
What is a progressive die?
A die with several stations that cut and form a strip step by step, producing a finished part with every press stroke.
Who owns the press tool?
Usually the customer pays for and owns the tooling, while it is maintained by the manufacturer. Terms are agreed at order.
