Best Quality Copper/Aluminum Busbar Fabrication MachineProduct Description:This
For a first busbar fabrication machine in a Saudi or GCC switchgear workshop, the LTMC 303U-3-C is the model we recommend, because one table covers punching, shearing and bending at 300 kN on busbar up to 12 mm thick and 160 mm wide. The three units are independent, so punch, shear and bend can be set up without re-clamping the bar, and the closed bending structure keeps horizontal bends and embossing uniform in volume production. Published accuracy for this class is ±1° bending with ±0.5° repeat, against roughly ±2° for hand-marked press-brake work. It suits electrical panel boards, LV switchgear, transformer terminals and busduct fabrication where contractors run mixed batches rather than one fixed part. Final configuration should be matched to the material size, process, throughput and tolerance stated on your purchase specification.

Figures below are stated against the acceptance conditions named in each paragraph so that every paragraph can be read on its own. Values are the published specification for the LTMC machine or series named; where a value is a category-level acceptance target it is labelled as such. This is a category-level acceptance benchmark and must be confirmed by a factory acceptance test (FAT) using the buyer’s own material and the ordered machine configuration.
Test conditions: 300 kN nominal force applied through the standard ф4.3–ф25 mm die set on 12 mm × 160 mm T2 copper busbar. Specified value: 300 kN maximum punching force with a ф4.3–ф25 mm punching diameter range. Comparison baseline: single-station hand punching, where hole position typically drifts ±1.0 mm across a batch; the closed 303U-3-C die frame is specified to hold concentricity instead of drifting.
Test conditions: repeated 90° horizontal bends on 12 mm × 160 mm copper busbar using the standard bending unit. Specified value: ±1° bending accuracy with ±0.5° repeat bending accuracy. Comparison baseline: manual press brake with hand-set stops, where ±2° and ±1° repeat are typical — the 303U-3-C specification is about 50% tighter on both figures.
Test conditions: 12 mm × 160 mm copper busbar cut on the double-column shearing unit. Specified value: 12 mm maximum shearing thickness and 160 mm maximum shearing width, with a flat, burr-free cut face. Comparison baseline: abrasive disc cutting, which leaves burrs and requires a secondary deburring pass.
