20Khz Ultrasonic Plastic Welding Machine for Thermoplastic Material

Ultrasonic welding is a fast, clean and effective assembly process. Used to assemble methods for processing thermoplastic fittings and some composite components. It is currently used for bonding between plastic products, bonding of plastic products to metal parts and bonding between other non-plastic materials. The energy generated by the ultrasonic generator is used to rapidly expand and contract the elastic vibration by the transducer under the magnetic field induction of the ultra-high frequency, so that the file is vibrated correspondingly, and a certain pressure is applied on the file, so that the file is in the two Under the combined action of the force, the AI wire is rapidly rubbed on the surface of the metallized layer of the bead, such as (AI film), and the surface of the AI wire and the AI film is plastically deformed. This deformation also destroys the oxide layer at the interface of the AI layer. The two pure metal surfaces are brought into close contact to achieve the bonding between the atoms, thereby forming a weld. The main welding material is aluminum wire welding head, which is generally wedge-shaped.

Application:

Because ultrasonic welding has the following advantages:

(1) energy saving

(2) ventilation device that does not need to be equipped with smoke dissipating heat

(3) low cost, high efficiency

(4) easy to achieve automatic production,

so ultrasonic welding in plastics, electronics, electrical appliances, automobiles Accessories, packaging, environmental protection, medical equipment, non-woven fabrics, toys, communications equipment and other industries are used. It replaces solvent glue, mechanical fastening and other bonding processes and is an advanced assembly technique. Ultrasonic welding not only has a connection assembly function but also has a moisture-proof and waterproof sealing effect. Therefore, it is widely used in the soldering of lead wires and metal coatings on silicon and silicon in electronic devices, soldering of various metals (aluminum, copper, gold, nickel) in integrated circuits with metal coatings on ceramics and glass, thermocouples. Welding, chemically active substances such as explosives, reagents, and package welding of explosives.
