Renewables and energy storage
Battery and inverter busbar work, where volume ramps fast and changeover time is the constraint.
Battery, inverter and energy-storage busbar work behaves like EV charging with a steeper ramp. Volumes rise quickly once a design is fixed, mixes are moderate, and the constraint tends to be changeover and programming time rather than cutting speed. Insulation and edge quality matter for the same reason they do in power electronics, and joint reliability matters more than usual because these assemblies are difficult to access once commissioned.

Technical background
Punching
Punch-to-die clearance for copper and aluminium busbar
How to set punch-to-die clearance per side on 6-20 mm copper and aluminium bar, read the sheared edge, and specify burr height on the drawing.
Bending
Springback compensation in busbar bending
How to predict and cancel springback in copper busbar bending: the governing ratios, a worked calculation, overbend by EN 13601 temper, and CNC offset tables.
Standards
Busbar hole patterns and what DIN 43673-1 actually specifies
What the four pages of DIN 43673-1 govern, the engineering behind edge distance, pitch and hole diameter, and why DIN 46433 is not a busbar standard.
Materials and finishing
Copper temper and minimum bend radius
How EN 13601 tempers R220, R240 and R290 set the minimum bend radius of copper busbar, how to read a mill certificate, and when annealing is the wrong answer.
