Blanking, piercing, forming and deep drawing on progressive dies — the process for brackets, contacts, clips and enclosures in the hundreds of thousands, with the die designed and built in-house.
Quick definition
Stamping runs sheet metal through a press and a die that cuts and forms it in a series of stations — blanking, piercing, bending and drawing — often in one progressive stroke. Once the die is built, parts come off in seconds at a very low cost each, which makes it the process for sheet-metal parts at high volume: contacts, clips, brackets and drawn enclosures.
A die that fits the part, not a generic one
Farm a stamping out cold and you get a die quoted before anyone checks the volume, a material chosen for the shop, and plating sourced somewhere else. OperGo designs the die around your part and volume, stamps it in the right gauge and alloy, and plates or finishes it under the same quote — so the tool and the parts come from one team that owns both.
What we run
Blank, pierce, form and draw across stations in one press stroke — the workhorse for high-volume sheet-metal parts.
Flat sheet drawn into cups, shells and enclosures — battery cans, housings and covers formed without a weld.
Precise flat blanks and hole patterns punched at speed, ready to form or to use flat.
Progressive and transfer dies designed and built in-house, then run and maintained on our own presses.

Picking a process
For prototypes and low-to-mid volumes, laser cutting and press-brake bending need no dedicated tooling. Once volume is high, a stamping die makes each part far cheaper and faster.
Machining suits thick, three-dimensional metal parts. Stamping suits flat or formed sheet-metal parts made in huge numbers from strip.
A stamped part needs a progressive or transfer die. We design and build it in-house and run it on our own presses.
Roughly from the high tens of thousands upward. Below that, laser cutting and press-brake bending avoid the die cost entirely. Above it, the stamping die's speed and low per-part price win decisively. Your engineer runs the crossover math on your actual volume.
It's a one-time tooling cost set by the number of stations, the size of the part and whether it's progressive or transfer. It amortizes over the run, so cost per part falls sharply as volume rises. We design and build the die in-house.
Cold-rolled and stainless steel, aluminum, and copper and brass for electrical contacts — from around 0.1 mm foil up to about 6 mm structural gauge, matched to strength, formability and conductivity.
Yes. Deep drawing pulls flat sheet into cups, shells and enclosures — housings, covers and battery cans formed in the die without a weld. It is designed into the die from the start.
Yes — deburring, plating (zinc, tin, nickel), passivation and painting are specified under the same quote, so parts arrive finished, not raw.
Then it's requoted as laser + bending for lower volumes, or CNC for thick three-dimensional parts. Opening this page doesn't commit you to a process.
