From the physical point of view, this process is completely a process of energy conversion. In the process of rotation, the motor drives the working height, and the cylinder is pulled to press down the rotating motor. When it comes into contact with the product to be welded, it stops moving instantaneously and converts strong mechanical energy into heat energy instantaneously. It is the rapid generation of heat between plastic molecules and hot melting, followed by pressure welding. At this time, the joint surface of the workpiece is solidified by the melt, and the rotating motor is quickly pulled up, Complete the welding procedure.
