Sonics to display new Ultrasonic Metal Welding System at the Assembly Show


20 kHz System Features Patented Left and Right Nodal Mounting Systems and Color Touchscreen Controller

Sonics & Materials, Inc. will be demonstrating its newly re-designed MW20 Ultrasonic Spot Welding System, now available in both right and left versions allowing multiple welders to be located within close proximity.  The system’s M-Series power supply provides microprocessor control, color touchscreen interface, power graphing and electronic pressure regulation in power levels from 1500 to 4000 Watts.

The MW20 is engineered to provide highly repeatable results with production-friendly features, such as the patented nodal mounting system that allows for industry-leading quick stack changes.   The self-orienting horn and tips are cost effective and simple to replace. The lab version has a large ground steel base that allows for easy tooling changes and integrated operator controls. A large anvil stage with independent x-y adjustment facilitates part fixturing and precision down/up stops provide total motion control.

Other standard features include convenient weld quality data storage options, upper and lower weld parameter limits, barcode reader and PLC interfaces. All models include soft-start overload protection circuitry, load regulation circuitry and power factor correction.
