iSDP series is DONGHO new generation of direct press servo ultrasonic metal welder, with ultrasonic system technology synchronised with Europe and USA. The stacked energy introduction method increases the vibration energy transmission, and the high frequency (20KHz) amplitude and pressure cause two larger workpieces to rub against each other generating heat to quickly fuse together.The iSDP series can be set up with a variety of parameters to program the welding process according to your product's needs. 100 % servo motor control, quality control using graphical analysis. Tighter standard deviations and process capability, ensure the best results for welding non-ferrous metals and alloys. The process is energy-efficient and suitable for welding thick sheets and large cross-sections of wire, etc.

The iSDP series is suitable for a wide range of applications including cable assembly and battery production, also including high voltage cables, battery terminals and battery connectors, all combinations of copper and aluminium are possible, especially complex hybrid connections, for both standard and special forms of battery cells.
