Working principle of high frequency/high frequency heat sealing machineHigh frequency machine, also known as high frequency (high frequency) plastic welding machine (also known as high frequency dielectric heating equipment), is the first choice for plastic heat sealing. It uses high frequency electric field to oscillate internal molecules of plastic to generate heat energy to fuse various products. .
The high-frequency machine is the induction heating equipment with the highest heating efficiency, the fastest speed, low energy consumption, energy saving and environmental protection for metal materials.
Working principle: high-frequency plastic welding equipment, which belongs to high-frequency medium heating equipment.
The working principle is dielectric material. Under the action of high-frequency electric field, molecular polarization occurs and is arranged according to the direction of the electric field. Due to the high-frequency electric field, the direction is changed at a very fast speed, then the dielectric material will heat due to dielectric loss .
About high frequency machine/heat sealing machine The detailed introduction is as follows:
The full name of the high-frequency machine is "high-frequency induction heating machine", which is called "high-frequency induction heating equipment" or "high-frequency power supply" in China, and it is also called high-frequency induction heating machine in Guangdong and Taiwan. Heat sealing machine, high frequency machine, high frequency sealing machine, heat sealing machine; because of different uses. Called high-frequency embossing machine, or embossing machine, clothing embossing machine, carpet embossing machine, mat embossing machine, door mat embossing machine, etc.
It is mainly for inductive heating of metals (non-contact); it can heat metals very quickly, which has the advantages of power saving, small size, convenient installation, convenient operation, safe and reliable, and fast heating speed.
High-frequency plastic welding equipment belongs to high-frequency medium heating equipment. Its working principle is dielectric material. Under the action of high-frequency electric field, molecular polarization occurs and is arranged according to the direction of the electric field. Due to the high-frequency electric field, the direction is changed at a very fast speed, then the dielectric material will be due to dielectric loss. fever.
Put plastic such as polyvinyl chloride between the electrodes and apply a certain pressure. When heated to form and cool for a period of time, the plastic can maintain this deformation. Using this feature, high-frequency embossing can be achieved Or high-frequency molding. If two or more pieces of plastic are heated to a hot-melt state, after cooling, they are firmly bonded together. Using this feature, high-frequency welding can be achieved.
