Design and Development:

RHI not only produce bus bars according to customer’s drawing, we also can help customer to design. If you have any doubt on designing bus bar for your battery pack or system, we can have meeting to discuss. And our technician can participate in your project to design an applicable and cost effective bus bar for you. We can make verification for new designs.

RHI has lab. We make test to confirm performance of the designed part before delivery. We can make metallographic test, bending test, pulling force test, aging test,salt spray test etc.

Metallographic Test: Metallographic testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. We usually use it to observe the gaps between layers after welding and analysis polymer diffusion welding quality.

Thermal Simulation: RHI simulate bus bar’s working condition, cooling condition and insulation to check its temperature rise. Thermal simulation can be applied at an early design stage. It helps engineers make better decisions and design more effective product parts.

Bending Test: RHI can makes bending test to check fatigue resistance of flexible busbars.

Salt Spray Test: Check the corrosion resistant performance of plating.

Our production range includes rigid, flexible, laminated, and extruded busbars, along with busbar covers. We handle all processes in-house except plating, which is completed by a nearby supplier. Our capabilities encompass cutting, welding, polishing, punching, bending, twisting, riveting, brazing, plating, insulation, and more. With advanced equipment including robot production lines and automation, we efficiently produce complex designs and increase production volume.
