Description

When the ultrasonic wave acts on the thermoplastic plastic contact surface, it will generate high-frequency vibration of tens of thousands of times per second. This high-frequency vibration reaches a certain amplitude, and the ultrasonic energy is transmitted to the welding area through the upper weldment. The acoustic resistance of each welded interface is large, so local high temperature will be generated. In addition, due to the poor thermal conductivity of plastics, it cannot be distributed in time and gathers in the welding area, causing the contact surfaces of the two plastics to melt rapidly. When the ultrasonic wave stops working, let the pressure continue for a few seconds to make it solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials. The quality of ultrasonic plastic welding depends on three factors: the amplitude of the transducer welding head, the applied pressure and the welding time. The welding time and welding head pressure can be adjusted, and the amplitude is determined by the transducer and the horn. These three quantities have an appropriate value for each other. When the energy exceeds the appropriate value, the melting amount of the plastic will be large, and the welding object will be easily deformed; if the energy is small, it will not be easy to weld firmly, and the applied pressure will not be large. This optimum pressure is the product of the edge length of the welded part and the optimum pressure per 1mm of the edge.

In contemporary society, various plastic products have penetrated into various fields of people's daily life, and are also widely used in aviation, ships, automobiles, toys, electronics and other industries. However, due to the limitation of injection molding process and other factors, some plastic products with complex shapes cannot be injection molded at one time, which requires bonding, and the plastic bonding and heat sealing processes that have been used for many years are quite backward, not only inefficient. , and the adhesive has a certain toxicity, causing problems such as environmental pollution and labor protection. This traditional process can no longer meet the needs of the development of the modern plastics industry, so a novel plastic processing technology - ultrasonic plastic welding stands out for its advantages of high efficiency, high quality, beautiful appearance and energy saving.
When welding plastic products, the ultrasonic plastic welding machine does not need to add any adhesives, fillers or solvents, nor does it consume a lot of heat sources. It has the advantages of simple operation, fast welding speed, high welding strength and high production efficiency. Therefore, ultrasonic welding technology is more and more widely used.

Selection of ultrasonic transducers

Ultrasonic transducer is an energy conversion device, its function is to convert the input electrical power into mechanical power (ie ultrasonic) and then transmit it out, while it consumes a small part of the power (less than 10%). Therefore, the most important issue to consider when using ultrasonic transducers is the matching with the input and output terminals, followed by mechanical installation and matching dimensions. There are many kinds of ultrasonic machines on the market. Customers must provide accurate and reliable indicators to ensure that the ultrasonic transducer products provided by the company can be well matched with your company's ultrasonic machines and exert the best performance.
Our company can provide various specifications and models of ultrasonic transducers.
