Principle For connecting the workpieces of differentmaterials, malleable plastic parts connected with each other or the connectionof plastic parts and metal parts; using a mold of a particular shape can beachieved hard plastic riveting, riveting column, hemisphere riveting, circularflange riveting, mechanical forging, punching, folding mosaic covering,connecting parts of hard brittle, beautiful, strong, good sealing, in order toachieve optional design structure. Features: A. Workpiece of different sizes can be used, noarea restrictions. B. Four columns (six columns) structure,completely eliminate the couple and backwards. C. Use extended liner bearing design, smoothmovement from top to bottom and highly accuracy. D. Fusing temperature, the delay time, weldtime, cooling time, input pressure and other parameters can be adjusted. E. Dual start button and emergency stop buttondesigned to ensure safety. Other optional welding parameters can also beadjusted. Application Areas: 1) Automotive parts (car door, duct, seats, etc.). 2) Electronic appliances (computer keyboard, LEDlights, cell phone case, piercing connector, terminal, connectors, etc.). 3) Medical devices (scalpels and other medicaldevices). 4) Commodity (ties, picture frames, jewelry,etc.)
