Automatic busbar punching, cutting and bending machine: 3 in 1, semi-automatic, high precision
The spatial design of copper busbars directly determines the heat dissipation capacity of electrical switchgear. Precise busbar punching, cutting, and bending are crucial for busbar layout and installation. SUNSHINE™ busbar processing machine: Professional 3-in-1 solution that meets this critical requirement for high and low voltage switchgear manufacturers. Unlike standard 3-in-1 busbar machine, Professional 3-in-1 busbar machine features four independent servo motors and high-precision roller screw. Whether punching, cutting, or bending, it can quickly and automatically locate the busbar processing position coordinates, eliminating the need for operator calibration using a ruler, greatly improving busbar processing efficiency.

Whether you’re bending, punching, or cutting busbars, the operator simply enters the parameters, and the Professional 3 in 1 busbar machine automatically locates the busbar processing coordinates, eliminating the need for manual positioning using a scale. This results in processing efficiency five times that of a standard 3-in-1 busbar machine. Another surprise is the machine’s program memory storage, meaning the operator only needs to enter parameters once and can simply call up the stored program in the future.
Mold list
Each of our busbar machines is standardly equipped with 5 sets bending molds, 8 sets punching molds and 1 set cutting mold. Our molds are made of Cr12Mov high-strength alloy steel, which has excellent wear resistance and strength, making the cross-section of busbar punching and cutting smooth and burr-free, and the service life is up to 30,000 times.
