Switchgear and panel builders
High-mix, drawing-driven work where engineering changes arrive weekly and lead time decides the order.
Panel building is drawing-driven, high-mix work: engineering changes arrive weekly, batch sizes are small, and the constraint is almost never raw machine speed. It is the time between a drawing landing and a finished bar leaving the machine. Three factors are therefore decisive. First, whether the machine reads CAD geometry directly or requires a re-drawing step. Second, tool change time, because a drawing set with four or five hole diameters spends more time changing tools than cutting. Third, nesting, because a shop cutting to drawing wastes bar it has already paid for. Capacity matters as well, though most panel work sits comfortably inside a 300 to 600 kN machine.

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.
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.
Standards
Which busbar standard applies to your job
A decision tree from product type, voltage class and destination market to the governing standard set, with each standard placed at its actual scope boundary.
Punching
Sizing press force for busbar punching
Work out the punching force a busbar job actually needs, from shear strength and hole perimeter, and match it to a 300-800 kN machine with sane margin.
