The principle of high frequency is: the high-frequency electromagnetic field is generated by the self-excited oscillator of the electron tube. The object to be processed is pressed between the upper and lower electrodes with a high-frequency electromagnetic field. The internal molecules are excited and move at high speed to rub against each other to generate heat and melt. The purpose of welding or embossing is achieved under the pressure of the mold.

High frequency plastic welding machine is a kind of equipment for plastic heat sealing. It is used for welding and cutting cardboard, blister welding and cutting, automobiles, leather pads, door panel hand guards, sun visors, welding and cutting of shoe uppers, soles, welding and cutting, Welding and cutting of trademarks, watch straps, leather cases, simultaneous fusing of paper cards and blister, etc. Extended information

Features

The high-frequency fuse machine has two slide positions. The operator only needs to put in the product and press the slide forward button, and the machine head will automatically lower, heat, and rise. , the slide table exits, and all simple operation processes are completed. The staff can use the machine without special training.

When the current exceeds the limit value, the overload current relay automatically protects the oscillation tube and rectifier. When the mechanical cooling is insufficient, the power supply can be automatically cut off, and accidents caused by improper operation can be avoided.
