Another value added service that we can provide to our customers is a process known as sonic welding. This process takes high frequency low amplitude vibration to create heat between the two materials that are to be joined. The interface of the two parts is specially designed to concentrate the energy for the maximum weld strength. In this welding process there are no connective bolts, nails, soldering materials or adhesives necessary to bind the materials together. Customers find this process cost effective and functionally attractive in meeting a wide range of assembly needs.
