Prototype to Serial Production for Sheet Metal Parts
Move a sheet metal part from prototype to serial without losing interchangeability: what to freeze before the tool is cut, and what a pilot batch must prove.

Stamping, presses and press tools
Ganesh runs mechanical presses from 20 T to 300 T, a 250 T punching press and an in-house tool room at Mumbai (Vasai). This is the material for engineers and buyers deciding between stamping, laser cutting and press forming: tooling cost, springback, draw ratios, minimum hole sizes, die maintenance and what a stamped part actually costs at volume.
Guides in this topic
Pressed, punched and deep drawn sheet metal parts, the tooling that makes them, and the DFM rules that decide whether a part suits a press at all.
Pressed metal components: when stamping is the right process
Pressed metal components: the tonnage, volume and tool-life numbers that decide whether stamping beats laser cutting and bending for your bracket.

Deep drawing design rules for production parts
Deep drawing design rules that decide whether a cup forms in one stroke: draw ratio, blank diameter, punch and die radii, clearance and tooling route.

Progressive Die versus Single-Stage Press Tool
Compare progressive and single-stage press tools on output per press, material utilisation, tolerance stack-up and the volume where the tool premium pays back.

Tooling cost versus piece price in metal stamping
How to compare a press tool against a per-piece route: the break-even formula, a worked example, what drives tool and piece price, and the costs after the PO.

Aluminium stamping: formability and tooling considerations
Aluminium stamping design rules: alloy and temper choice, die clearance, blanking tonnage, pickup, earing and the springback that opens a bend.
