Ultrasonic welding technology

Ultrasonic welding is used to transfer to the surface of two objects to be welded by high frequency vibration wave. In the case of pressure, the surface of the two objects is rubbed with each other to form the fusion of the molecular layer. It is a quick, clean and effective assembly process for assembling thermoplastic parts and some synthetic components. At present, it is used to bond between plastic products, bond between plastic and metal parts and other non plastic materials. Ultrasonic welding is used to transfer ultrasonic energy to welding area through upper welding parts. Because of the large sound resistance at the interface of two welding joints, local high temperature will be produced. Because of the poor thermal conductivity of the plastic, it can not be distributed in time in time, gathering in the welding area, resulting in the rapid melting of the two plastic contact surfaces, combined with certain pressure, to integrate them into one. When the ultrasonic stop action, let the pressure last a few seconds to solidify, thus forming a solid chain of molecules to achieve the purpose of welding, the strength of the welding can be close to the strength of the raw material. Applicable industries: plastics, electronics, electrical appliances, auto parts, packaging, environmental protection, medical devices, non-woven fabrics, toys, communications equipment and other industries. It has replaced the solvent adhesive, mechanical fixation and other bonding technology. It is an advanced assembly technology. The ultrasonic welding has not only connection assembly function but also moisture proof and moisture proof sealing effect.
