For the concept of hot plate machine and hot melt machine, everyone may be a bit vague. there must be differences between them, but at the same time, there are also common points. today Nico’s editor will lead you to learn the related welding of hot plate machine and hot melt machine. Knowledge.

The hot plate machine adopts a plate-drawing structure, and the heat of the heating plate is transferred to the welding surface of the upper and lower plastic heating parts by the electric heating method. The surface is melted, then the heating plate is quickly withdrawn, and the upper and lower heating elements are heated and the melting surfaces are fused, solidified, and integrated. The whole machine is in the form of a frame, composed of three plates: an upper template, a lower template, and a hot template, and is equipped with a hot mold and an upper and lower plastic cold mold. The action mode is pneumatic control and manual mode. mainly suitable for welding plastic parts such as household appliances, car lights, and automobile melters.

The hot plate machine can set the heating power and mold size according to the size of different plastic parts to realize the welding of a variety of plastic workpieces, with simple operation and convenient use. The heating plate is composed of two upper and lower parts, which are heated by electric heating tubes. This machine is equipped with two temperature controllers to control the temperature of the upper and lower molds respectively. During welding, it can be set in the range of 0～600℃ according to the actual needs during welding. The control mode of this equipment can be divided into manual and automatic control. manual is a single action, which is mainly used for the debugging of mechanism and mold. after manual debugging, it is adjusted to automatic during production. The automatic control system adopts programmable logic controller (PLC) and touch screen man-machine interface to control, the movement of each cylinder is driven by air pressure, which is easy to operate, reliable in performance, compact in size, and improves production efficiency and quality.

The hot melt machine has been widely used as a special machine or used in conjunction with an automatic machine. The use of relatively high-performance heaters and thermocouples can be used to control the heating temperature very well, which can make the processing more stabilization and efficiency.

generally speaking, current hot melt machines are basically used between plastics and metals. The main processes are riveting, riveting, hot-melt forming, and hot-melt cutting. Moreover, since hot melting does not have very high requirements for the material of the product, for general plastics, it basically does not need to be welded. after welding, it can ensure that the fastness of the product is basically more than 80% of the body.
