Springback in sheet metal: predicting and correcting it
Why a stamped bend opens after the tool releases, how yield strength and radius set the amount, and the die changes that bring the part back to the drawing.

Stamped battery contacts and tabs
Current, spring force and plating decide whether a stamped battery contact holds its resistance over a pack's life, and where a tab joint becomes the weak point.

Stamped motor laminations and rotor plates
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.

Bend radius and bend allowance in stamped parts
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.

Blanking clearance and edge quality
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.

Busbar for transformers
A transformer connection has to carry current, survive a fault and hold its insulation for decades. Bracing and clearance are the design, not an afterthought.

In-die tapping and countersinking: design and cost
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.

Progressive die stamping: how a coil becomes a finished part
The station sequence, strip layout and tooling decisions that turn a coil into a finished stamping, and the volumes that justify the die.

Stamped terminals and connectors
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 direction and burr height: what to call out
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.

Busbar for inverters and UPS
The DC link and output path in a switching assembly is a geometry problem: keep the loop small, keep the joints cool and keep the build repeatable.

Scrap and material utilisation in stamping
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.

Go from reading to checking
The guides are built around the same questions as the free tools. Size a busbar, check an ISO 2768 callout, build a first article report or compare landed cost.
