 Plastic hot melt machine by electric heating method heating plate heat transfer to the upper and lower parts of plastic heat welding surface. To surface melting, and rapid exit of the heating plate, up and down two pieces of heated molten surface heat fusion, curing, together as one. Form the framework of machine, from the template, the next template, three large panels heat the template, and with a hot mold, the upper and lower plastic cold model, action, pneumatic control. Mainly used in household appliances, lights, cars, etc. plastic welding solution. Plastic parts according to different heating power and die size is set to achieve a variety of plastic parts weld size, simple operation, easy to use. Formed by the two upper and lower heating plates, heating them with a heating pipe. 

 Ultrasonic welding machine has three processes: the first is the ultrasonic plastic welding, using ultrasonic high frequency vibration friction and heat welding the opposite principle; second is ultrasonic welding, ultrasonic high frequency vibration friction and heat the product theory point of welding rivet ; third is the hot-melt welding, electric heating principle is to make parts of the surface melted and stuck together.
