The PVC blister heat sealing machine, edge pressing machine, and high-frequency welding machine are widely used equipment in the plastic packaging industry. Their working principle is primarily based on high-frequency dielectric heating technology. Below is a detailed introduction to this equipment:

Working Principle

The PVC blister heat sealing machine, edge pressing machine, and high-frequency welding machine generate a high-frequency electric field through an electronic self-excited oscillator. This high-frequency electric field is applied to the electrodes. Under the influence of the high-frequency electric field, the molecular structure of the plastic undergoes polarization, generating heat internally. This, combined with pressure, achieves the purpose of thermal melting, enabling welding and edge pressing functions.
