This grading card slabs ultrasonic welding machine are widely used for sealing, welding, riveting, spot welding of thermoplastic parts such as electronic products, plastic products, stationery & toy, video & audio products, automobile & motorcar fittings, meters, household appliance, socket and plastic pipe as well as inlaying between metal and plastic products .

This ultrasonic welding grading card slabs machine can transfer electric energy into ultrasonic energy by the ultrasonic transducer inside and pass them to plastic workpiece through welding noild and make its interface quake and scrape violently and produce heat of fusion to achieve the welding effects. The ultrasonic welded plastic workpiece has the characteristic of good quality, sealing and high-strength welding seam. By changing the difference welding horn, different area and shape workpiece can be welded.
