Product Description: 303U-3-C Manual Hydraulic Busbar Machine
Model: 303U-3-C

This versatile series of 3-in-1 Busbar Processing Machines integrates three essential workstations: punching, shearing/cutting, and bending. The three units can be operated simultaneously or sequentially, allowing for maximum flexibility in your workshop. The working stroke of each unit is easily adjustable, which significantly shortens processing time and boosts production efficiency for switchboard builders. Its primary function is the fabrication of Copper and Aluminium busbars.
Equipped with independent hydraulic units for punching, shearing, and bending, this machine offers precise control via manual buttons or a foot switch. You can punch, cut, and bend busbars separately, making it an ideal production asset for the high and low voltage electrical industry in Australia.
Designed with reference to advanced international engineering standards and tailored for practical site conditions, this busbar machine improves workflow efficiency while ensuring operational safety. It is perfectly suited for construction sites, large-scale electric control box assembly, and power transmission and distribution projects.

Main Features for Australian Users:
1. Shearing Unit: Uses a vertical processing mode with flat blade cutting, ensuring a burr-free, waste-free, and smooth interface.
2. Punching Unit: Equipped with a six-mode turret turnplate (tooth shape) for better visibility. No need to frequently change dies, making operation simple and efficient.
3. Bending Unit: Features a horizontal bending station. By simply changing molds, you can switch between flat bending and vertical bending easily.
4. Versatility: Additional functions like embossing, flattening, twisting, and cable end crimping can be achieved with specific molds.
5. Mobility: Mounted on four heavy-duty casters, allowing easy movement around your workshop or construction site.
6. Customisation: We provide different molds and tools tailored to user requirements for special shape processing.
