Topic hub
Stamping rewards parts that are designed around the tool from the start. This section covers strip layout, bend design, tolerances, tooling economics and the defects that show up after the first trial.
Material grade, profile design and stacking decide the magnetic path, the mechanical fit and the burr that ends up inside the core. A practical guide for buyers and design engineers.
How the neutral axis, the K-factor and the bend deduction set the flat pattern, with a worked example, minimum radius guidance and the tooling limits behind both.
Clearance per side decides the split between rollover, burnish, fracture and burr. It also decides how hard the press works and how long the die lasts.
When a thread or a countersink belongs inside the press, when it belongs in a secondary cell, and the drawing calls that decide which route is cheaper.
The station sequence, strip layout and tooling decisions that turn a coil into a finished stamping, and the volumes that justify the die.
Terminal geometry, material temper and plating decide whether a stamped connector crimps well, holds its spring and survives the environment it was chosen for.
Burr is a normal result of shearing, not a defect to argue about at goods in. A side, a height and a measurement method turn it into a specification.
Where the metal goes in a progressive strip, how nesting and strip layout change the yield, and how to price scrap honestly instead of treating it as a rounding error.
When a flat conductor should be punched from strip rather than machined from plate, and the geometry that decides whether the stamped route holds its current rating.
A plain guide to the press, the die and the operations behind a stamped part, plus the geometries and volumes where stamping is the right route.
Why three flat parts that look alike need different drawings, different tolerances and different inspection.
How to design a sheet metal enclosure that closes cleanly, bonds reliably and keeps its edges safe through assembly and service.
