Ultra Sonic Welder Ultrasonic Plastic Welding Machine

Ultra Sonic Welder Ultrasonic Plastic Welding Machine

Ultra Sonic Welder Ultrasonic Plastic Welding Machine works in principle of inducing ultrasonic frequency in thermoplastic components boning that is converted into heat between the welded plastic laminates, frictional heat is produced and dispense at the energy director built in the connecting joints, because of low heat conduction in thermoplastic, under the controlled pressure applied, the insoluble sealing is happen, the connection is forged in a very short period of time, the melting point of both working pieces is nearly equivalent which helps to form an uniform weld area, the welded area is usually as strong as the matrix material

02: Application

Ultrasonic welding of thermoplastic materials creates a molecular bond within the welding seam, longitudinal vibrations in frequencies of 15khz, 20khz and 35khz with tool amplitudes between 5um and 50um are introduced into the plastic materials under the action of force, ultrasonic vibrations are focused by means of special design of components of tools, this specific geometry within a component is referred to as energy director, the contact points in the joining area actively molded by means of energy input to achieve elastic deformation occurring between the contact surfaces and within the molecule chains generates heat that causes the materials to melt

03: Highlighting
