Ultrasonic Thermoplastic Welding Machine
Ultrasonic thermoplastic welding refers to the high-frequency vibration of tens of thousands of times per second when ultrasonic waves are applied to the contact surface of thermoplastic plastics, reaching a certain amplitude of high-frequency vibration. The ultrasonic energy is transmitted to the welding area through the upper welding piece. Due to the high acoustic resistance at the junction of the two welds, local high temperature will be generated. Due to the poor thermal conductivity of plastics, they cannot dissipate in a timely manner and accumulate in the welding area, causing the contact surface of the two plastics to quickly melt. With a certain amount of pressure, they fuse into one. After the ultrasound stops acting, let the pressure continue for a few seconds to solidify and form a strong molecular chain, achieving the purpose of welding. The welding strength can be close to the strength of the raw material.
Automobile
Ultrasonic thermoplastic welding is widely used in automotive manufacturing to connect various plastic components, including exterior parts such as bumpers, fenders, wheel covers, deflectors, etc; Interior parts: such as dashboard, door inner panel, auxiliary dashboard, glove compartment cover, seats, rear guard panel, etc; Functional and structural components: such as fuel tank, radiator water chamber, air filter cover, fan blades, soundproof cotton, soundproof felt, door panels, etc

Package
Ultrasonic thermoplastic welding is widely used in the packaging field, especially in food packaging where it performs well. The use of high-frequency vibration to melt and fuse the surface of plastic workpieces, achieving sealing and connection, has many advantages.
Ultrasonic thermoplastic welding is mainly applied in flexible packaging, suitable for vertical bags, chain bags, etc., to ensure the sealing of packaging and the shelf life of products; Capsules and tea bags: used for membrane sealing, sealing ring welding, and filter embedding to ensure the sealing of the packaging and the safety of the product; Nozzle, air valve, and zipper: Ultrasonic technology can quickly and safely weld injection degassing valves or nozzles, while maintaining the barrier properties of the film and allowing for the addition of safety zippers; Carton packaging: Suitable for coating carton packaging materials to ensure tight sealing, even if the products inside have a wetting effect, they can still maintain sealing; Thermoplastic packaging: such as capsules, bags, beverage cartons, cups, and plates, etc. Ultrasonic sealing provides a variety of options and achieves efficient sealing in the case of product residue in the seam area
Toy
Ultrasonic welding melts and fuses thermoplastic materials through high-frequency vibration, forming strong molecular chains. The welding strength is close to the strength of raw materials and is suitable for assembling and connecting various plastic toys.
In toy manufacturing, ultrasonic welding is commonly used to connect plastic parts, such as assembling various parts of toys. For example, the body and wheels of toy cars, as well as the various limbs of toy animals, can be firmly connected together through ultrasonic welding. This welding method is not only easy to operate, but also does not require the use of flux and external heat sources, avoiding deformation and residual stress problems caused by heating.
