Successful ultrasonic solutions for wire and terminal applications
Wire to terminal
In modern motor vehicles, connections of cable and contact part are indispensable, especially when it comes to ensuring the transmission of high power in the cable harnesses. Ultrasonics is used to weld copper or aluminum cables with cross sections ranging up to 150 mm² to the terminals.
Ultrasonic welding has proven to be a particularly suitable joining technology for these applications, as the connection produced meets even the highest demands in terms of strength and durability.
A special form of cable to terminal applications is the welding of high-voltage cables. They are essential for the success of electromobility, but due to their large diameter, a reliable connection requires a lot of power. With forces of up to 6000 N (1348 lbf), ultrasonic welding machines are perfectly suited for permanently and firmly joining high-voltage cables.
Low cycle times are possible even for cables with a cross section of up to 150 mm², ensuring economical production.
Busbar / terminal to terminal
When welding terminals or busbars, sheets with a thickness of up to 5 mm are welded together. These are used when high currents have to be transmitted, as for example in battery management systems or high-current contacts. Therefore, the force and power requirements are also considerably higher.
With ultrasonics, the connections can be welded in fast cycle times without having to accept losses in conductivity.
