High-frequency heat sealing assembly of hemodialysis drip buckets and accessories
In the high-frequency thermal welding assembly of hemodialysis drip chambers and accessories, high-frequency thermal welding machines play a critical role. The detailed analysis is as follows:
Working Principle
The high-frequency (HF) thermal welding machine generates a high-frequency electromagnetic field through a vacuum tube self-excited oscillator. The hemodialysis drip chambers and accessories to be processed are pressed between the upper and lower electrodes within this electromagnetic field. Under the influence of the high-frequency electric field, the dielectric material undergoes molecular polarization, aligning its molecules with the direction of the electric field. As the electric field direction changes rapidly, the internal molecules of the material are excited into high-speed motion and friction, generating heat internally. Under the pressure of the mold, this process achieves the goal of welding or assembly.
