Ultrasonic welding
Ultrasonic welding, also known as ultrasonic welding, is usually used for plastic welding. It is a high-tech technology for welding thermoplastic products, which can completely replace glue bonding. All kinds of thermoplastic rubber parts can be treated by ultrasonic welding technology without adding solvents, adhesives or other auxiliary products. The principle is that the ultrasonic energy is transmitted to the welding area through the upper weldment, and the high acoustic resistance at the interface of the two weldments is used to generate local high temperature to fuse the weldments together.
principle
Ultrasonic welding is a high-tech technology for welding thermoplastic products. All kinds of thermoplastic rubber parts can be treated by ultrasonic welding without adding solvents, adhesives or other auxiliary products. Its advantage is to increase multiple productivity, reduce costs, improve product quality and safety production. The ultrasonic energy is transmitted to the welding area through the upper weldment. Because of the large acoustic resistance at the interface of the two welding areas, the local high temperature will be produced. Due to the poor thermal conductivity of the plastic, it can not be distributed in time for a while, and gathered in the welding area, resulting in the rapid melting of the contact surfaces of the two plastics, plus a certain amount of pressure, so that they are integrated. When the ultrasonic stops, let the pressure last for a few seconds to make it solidify and form, so as to form a solid molecular chain, achieve the purpose of welding, and the welding strength can be close to the strength of raw materials.
Ultrasonic welding is usually used for plastic welding. It completely replaces the traditional industry of glue bonding. In the process of ultrasonic welding, there is no combination of bolts, nails, snaps, welding materials or adhesives. It is faster than the traditional adhesive or glue bonding, and the drying time is very fast. The welding process can be easily automated and easily customized To adapt to each type of specific specification of the product being welded.
