Hydraulic Busbar Bending Machine
The Hydraulic Busbar Bending Machine is a dedicated machine for flat bending copper and aluminum busbars. Vertical or edge bending is available on confirmed machine models using dedicated tooling. Material loading remains manual on the listed models, while positioning and bending control depend on the selected machine configuration. The CNC Servo model uses PLC and servo-assisted positioning, while the Double-Head model is designed for simultaneous end forming in busduct production.

Final capacity must be confirmed against the customer’s material specification, dimensioned drawing and selected tooling.
Interchangeable Tooling for Different Busbar Profiles
Different electrical products require different bending geometries. Instead of using one universal die, selected machine models can be configured with interchangeable tooling for different bend geometries.
Dedicated tooling may be evaluated for narrow-leg bends, large-radius bends, offset or Z bends and vertical bending. Feasibility depends on tooling access, busbar dimensions and part geometry.Tool selection should always be confirmed according to the finished drawing, material specification and required bending sequence.
Controlling Bend Radius and Springback
Achieving the required finished angle involves more than applying hydraulic force. Material properties influence the final angle after unloading, particularly when processing aluminum or high-conductivity copper.The machine is designed to work with appropriate bending tooling that controls deformation throughout the forming process.
Tooling radius and die geometry influence material deformation, inside radius and springback during forming. Final bending results depend on material yield strength, temper condition, bend radius, tooling geometry and the required finished angle.
Busbar Components Supported with Confirmed Tooling
With suitable tooling, the machine can produce a wide variety of busbar configurations used in electrical equipment manufacturing, including:
- Standard L-shaped busbars
- Offset busbars
- Double-bend conductors
- Edge-bent busbars
- Short-leg busbars
- Multi-angle busbar components
The machine is suitable for flat bending as standard and can also perform edge bending, offset bending and other special bending operations with compatible tooling. The available bending configuration depends on the selected tooling and machine model.
Tooling is selected according to the customer drawing, including material type, busbar dimensions, bend radius, leg length and finished angle. Customized tooling can be supplied for special applications.
No. The standard machine is manually operated and does not require CNC programming. Operators position the workpiece, install the required tooling and activate the hydraulic bending cycle.
Yes. The machine is designed for both copper and aluminum busbars. Final processing capability depends on material grade, thickness, temper condition and required bend geometry.
Yes. Special bending punches and dies can be designed according to customer drawings for non-standard busbar profiles, special bend radii or unique electrical component requirements. Capacity confirmation is recommended before production.
