Best Quality Copper/Aluminum Busbar Fabrication Machine

Measured data and reference conditions — 303E-3-S

Values per the model datasheet. Each paragraph is self-contained and states the test condition, the value and the comparison baseline.

Three functions in one clamping

Test condition: a copper bar of 12 mm thickness and 160 mm width processed on all three units of the 303E-3-S. Value: 300 kN punching force, a 12 × 160 mm cut and 300 kN vertical bending. Comparison baseline: a bench made of three single-function machines, where the part travels between stations. Effect: the bar is processed without leaving the machine, removing internal transport and handling damage.

Bending repeatability in serial production

Test condition: continuous production of parts at the same bending angle. Value: ±1° bending accuracy with ±0.3° repeatability. Comparison baseline: a hydraulic bending machine with a manual stop, whose spread between parts grows over a shift. Effect: ±0.3° repeatability keeps parts identical within the batch, which is what serial busbar assembly requires.

Punching on a 160 mm wide bar

Test condition: a 160 mm wide bar with holes of several diameters. Value: a punching range of Φ4.3 mm to Φ25 mm at thicknesses up to 12 mm. Comparison baseline: hand drilling with a template, limited by thickness and prone to exit burrs. Effect: round and oblong holes come out finished in the same pass, with no finishing step.

Weight and power for a panel workshop

Test condition: installation in a panel-building workshop. Value: 3 × 4 kW of total power, 1,420 kg of weight and a 1,800 × 1,400 × 1,480 mm footprint. Comparison baseline: larger 3-in-1 processing machines such as the 803U-3-C, which weighs between 1,400 kg and 2,100 kg depending on power class. Effect: it fits workshops with limited space and a standard three-phase supply.
