According to literature, the 15 k Hz ultrasonics assembly system goes beyond the capabilities of comparable systems by providing 4,000 W of power. The assembly system can handle large parts and soft materials thought by many to be difficult or impossible to assemble ultrasonically. In many cases, the system is said to be a viable alternative to much costlier technologies such as vibration welding. The system’s generator is the DPC IV Plus with advanced features such as Hot Keys for faster setup, three separate data, status and power displays, and automatic tuning for repeatable welds. Plug-in modules add to the generator’s versatility. The system is designed for appliance and other markets that assemble larger parts that require more pressure and amplitude. The heavy-duty press is built around an ultra-rigid support column with rack and pinion height adjustment and 10 degrees of radial alignment. The rugged construction means the press can easily handle large horns and tooling, further adding to the system’s application range. A heavy-duty slide assembly with sealed bushings provides smooth, frictionless operation. Standard features are said to include front-panel digital amplitude adjustment in 1-percent increments. Upper and lower limits can be set for SPC documentation, and alarm outputs notify the operator of suspect or bad parts. Also standard are primary and secondary weld collapse or absolute distance, energy, peak power, and time modes. An optional electronic regulator and load cell allow for precision trigger force and weld pressure profiling. Dukane Corporation,
