The welding head of the ultrasonic ultra-high frequency vibration generates frictional heat on the joint surface of the two plastics under appropriate pressure, and melts and joins in an instant, and the welding strength can match that of the main body. With suitable workpiece and reasonable interface design, watertightness and airtightness can be achieved, avoiding the inconvenience caused by the use of auxiliary products, and realizing efficient and clean welding. First, the integration of different products
Ultrasonic Plastic Welding machine joins rubber parts according to vibration. The higher the frequency, the smaller the amplitude and the smaller the relative output power. Therefore, the high frequency (40khz/35khz) two-protection welding machine is used for welding rubber parts with small specifications and high precision. The 28khz secondary protection welding machine is mostly used for hand-held nut spot welding machines, and the 20khz/15khz ultrasonic secondary protection welding machine is used for dissolving large and complex rubber parts. The higher the output power, the smaller the output power of the ultrasonic equipment and the lower the frequency, the greater the output power of the ultrasonic automatic welding machine.
2. The specifications of ultrasonic abrasives are different
Ultrasonic abrasives are commonly used half-wave ultrasonic molds. Ultrasonic welding abrasives with different frequencies have different length specifications. 40k abrasives (7cm), 35khz (8cm), 28khz (10cm), 20khz abrasives (13cm), 15khz abrasives with (17cm). Accurately measuring the length of the ultrasonic abrasive tool is one of the key indicators to distinguish the frequency.
Three, ultrasonic ultrasonic sensor structure is different
High-frequency welding machine (40khz, 35khz, 28khz) ultrasonic transducer structure is separated (ultrasonic transducer + horn are independent components), desktop integrated machine (20khz, 15khz) ultrasonic transducer structure is integrated ( Ultrasonic transducer + horn).
Application field
Trolley: Electric welding of large objects and irregular steel, such as bumpers, front and rear doors, lighting fixtures, brake lights, etc., can be performed according to the control of the electronic computer system.
Household appliances: According to proper adjustment, it can be used for portable fluorescent lampshades, steam ironing doors, TV casings, audio recorders, fully transparent control panels for audio machines, switching power supply ballasts, automatic washing machine dehydration tanks and other electrical appliances that must be sealed, sturdy and beautiful. product.
Packaging: Plastic hose seal, unique plastic packaging with connection.
Small toys: Due to the choice of ultrasonic technology, the goods are clean, efficient and strong, without the use of screws, adhesives, super glue or other auxiliary materials, which reduces the cost of products and improves the competitiveness of enterprises in the sales market.
Electronic equipment: The use of automation technology design solutions allows customers to surpass industrial production and ensure product quality requirements.
