Principle of ultrasonic welding, ultrasonic welding is a welding thermoplastic plastics technology, various kinds of thermoplastic rubber pieces of all can use ultrasonic welding processing, without having to add solvent, bonding agent, or other supplements. More than its advantage is to increase productivity, reduce costs, improve product quality and safety in production of ultrasonic plastic welding principle is 20 KHZ (or 15 KHZ) generated by the generator of high voltage, high frequency signal, can by changing the system, the signal is converted to high-frequency mechanical vibration, and on the plastic workpiece, through the workpiece surface and the friction and make the transfer to the interface between the molecules of temperature, when the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melting, and then fill in the space between the interface, when the shaking stops, workpiece cooling under certain pressure setting at the same time, to achieve perfect welding. 15 KHZ ultrasonic plastic welding machine, new type of welding with a softer PE, PP material, and large diameter, the length of the super-long plastic welding parts, has a unique effect, can meet the needs of a variety of products, production efficiency and product class contribution for users.
Ultrasonic welding technology:
By, ultrasonic welding, ultrasonic high frequency vibration welding head under moderate pressure, make the combination of the two pieces of plastic surface produces friction heat and melting joint moment, using the appropriate artifacts and reasonable interface design, can achieve watertight and airtight, and avoid using supplements such inconvenience, implement effective clean welding welding strength can be comparable to the ontology,
2. Riveting method:
The welding head of ultrasonic ultra high frequency vibration is pressed to the top of the top of the plastic, which makes it instantly hot and melt into rivet shape to make different materials.
The material machinery riveted together.
Through the conduction of welding head and proper pressure, the metal parts (such as nuts, screws, etc.) can be squeezed into the reserved plastic hole in a moment, and fixed at a certain depth.
After completion, no matter the tension and torque can be compared to the strength of the traditional mold, it can avoid the defects of the injection mold and slow shooting.
