The principle of ultrasonic welding
Through the weldment sends the ultrasonic energy to the welding area, due to the welding area is two welding interface of the acoustic resistance is big, so can produce local high temperature.Again due to poor thermal conductivity of plastic, can't timely send out for a while, gathered in welding area, the two plastic contact rapidly melting, coupled with a certain pressure, make its merging into one.When ultrasonic stop function, to keep the pressure, have a bit of the holding time, make its solidification molding, forming a strong chain, achieve the purpose of welding, the welding strength can close to the raw material ontology strength.
Ultrasonic welding it is usually used for plastic welding, it completely take the place of use glue and traditional industries, in the process of ultrasonic welding is not even the bolts, nails, card clasp, welding material or material such as glue together, it is more quickly than the traditional adhesive or glue water and the drying time is very fast, can easily achieve automatic welding process, can be easily customized, so as to adapt to all kinds of specifications of products are welding.
