Use electric hot plate machine principle control melting temperature changes, supported by a sound mechanism to achieve the perfect welding, ultrasonic welding machine to compensate for the lack of large and special plastic welding workpiece. Mainly suitable for PP, PE and other thermoplastic materials and weld area the size of a large and complex piece of plastic welding. Main features: 1. According to product requirements, drive servo motor. 2. Welding temperature, heating time, cooling time, welding depth, welding pressure, transfer time and other parameters can be adjusted. 3. According to the requirements of the welding procedure, choose semi-automatic or fully automatic mode. 4. According to the needs of different welding materials, adjust the welding process. Hot plate machine equipment use: The device uses the principle of hot plate welding machine can weld the reliability of plastic products, such as steam iron welding, automotive plastic tanks, automobile brake oil cups, plastic containers, plastic shaped taillights and other products.
