Standard HF Welding Machine High Efficiency, High Quality, Beautiful, Energy Saving

With the rapid development of the material industry, the application of the composites with light weight, small friction, corrosion resistance and easy processing of plastics and their metals has been paid attention to. Plastic products, has penetrated into people's daily life in various fields, but also widely used in aviation, ships, automobiles, electrical appliances, packaging, toys, electronics,Standard HF Welding Machine textiles and other industries. However, due to the limitations of the injection molding process and other factors, in a considerable part of the shape of complex plastic products can not be injection molding, which requires bonding, and the use of multi-year plastic bonding and thermal process is quite backward, not only the efficiency of low, and adhesive agents have a certain poison *, causing environmental pollution and labor protection problems. The traditional technology can not be applied to the development of modern plastics industry, so a new plastic processing technology-ultrasonic plastic welding with its high efficiency, high quality, beautiful, energy-saving advantages * stand out. Standard HF Welding Machine in the welding of plastic products, that is, do not fill in any adhesive, fillers or solvents, also do not consume a large number of heat sources, with simple operation, welding speed, high welding strength, production efficiency and high advantages. Therefore, ultrasonic welding technology has been more and more widely used.

When the ultrasonic wave acts on the plastic contact surface of thermoplastic *, will produce tens of thousands of times per second high-frequency vibration, this reach a certain amplitude of high-frequency vibration, through the welding piece to the ultrasonic energy transfer to the weld area, as a result of the weld area of two welding interface at the junction of large acoustic resistance, it will produce local high temperature. Also because of the plastic heat conduction * poor, temporarily can not be distributed in time, gathered in the weld area, resulting in two of plastic contact surface melting rapidly, coupled with a certain pressure, so that the integration into one. When the ultrasonic stops, let the pressure last for a few seconds, so that it solidifies,Standard HF Welding Machine forming a strong molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of raw materials. Ultrasonic plastic welding is good or bad depending on the amplitude of the transducer welding head, add pressure and welding time, such as three factors, welding time and welding head pressure can be adjusted, the amplitude by the transducer and luffing rod decision. These three quantities have a suitable value for each other, when the energy exceeds the suitable value, the plastic melts the quantity to be big, the welding material is easy to deform; If the energy is small, it is not easy to weld, the pressure can not be large. This optimal pressure is the weld part of the length with the edge of the best pressure per 1mm product.

1, weld the ultrasonic vibration with the welding head will be transmitted to the welding parts, because the two welding parts of the sound resistance, resulting in a local high temperature, so that the interface melting. Under a certain pressure, so that the two welding pieces to achieve a beautiful, fast, strong fusion effect.

2, inserting the nut or other metal to insert plastic workpiece. First of all, the ultrasonic wave to the metal, by high-speed vibration, so that the metal directly embedded in the molding plastic,Standard HF Welding Machine while the plastic melting, the completion of the solidification of the embedded.

3, riveting method to metal and plastic or two pieces of the different plastic bonding, can use the ultrasonic riveting method, so that welding parts are not easy to crisp, beautiful, solid.

4, Spot welding method using small welding head will be two pieces of large-scale plastic products points welded, or the entire row of tooth-shaped welding head directly pressure on two pieces of plastic workpiece, so as to achieve the effect of spot welding.

5, the molding method uses the ultrasonic wave to melt the plastic workpiece instantly, when the plastic solidification can make the metal or other material plastic firm.

6, the Excision method uses the special design method of the welding head and the base, when the plastic workpiece just shoots out, directly presses on the plastic branch, through the ultrasonic conduction achieves the excision effect.
