Busbar Manufacturing: Process, Machines & Cost Guide

August 21, 2024

Busbar manufacturing is the process of turning copper or aluminum bar stock
into finished electrical conductors. It follows six stages: material selection, cutting,
punching, bending, surface treatment and quality testing. Each stage uses dedicated machines
and must meet IEC 61439-1 tolerances for current rating, temperature rise and mechanical strength.

Busbar Manufacturing Process in 6 Steps

Material selection: Choose ETP copper (C11000) or 6101-T6 aluminum bar stock.
Cutting: Cut to length within ±0.1 mm using a busbar cutting machine.
Punching: Punch bolt holes, keeping edge distance at least twice the hole diameter.
Bending: Form angles with a bend radius of at least 1.5× the bar thickness.
Surface treatment: Apply tin, nickel or silver plating to prevent oxidation.
Quality control: Verify dimensions, conductivity and temperature rise to IEC 61439-1.
