Ultrasonic plastic welding machine mainly uses a frictional heat generated by the contact surfaces of two workpieces to be welded to melt the plastic. Thermal energy It is mainly from a certain pressure below, a workpiece reciprocating movement on the other surface with a certain displacement or amplitude. It is assumed that once the desired degree of welding is reached, the vibration will stop and a certain amount of pressure will still be applied to the two workpieces, so that a portion that has just been welded is cooled and solidified to form a tight bond.
How does the orbital vibration friction ultrasonic plastic welding machine work?
Orbital vibration friction welding is mainly a method of welding by frictional heat. In the case of orbital vibration friction welding, the upper workpiece is mainly a circular motion in all directions of orbital motion at a fixed speed. The movement can generate thermal energy so that the welded portions of the two plastic parts can thus reach the melting point. Once the plastic begins to melt, the movement stops and the welded parts of the two workpieces solidify and are firmly joined together. A small clamping force results in a minimal deformation of the workpiece, and workpieces with a diameter of 10 inches can be welded by applying orbital vibrational friction.
