The synchronous welding high-frequency machine is a professional piece of equipment that utilizes high-frequency electromagnetic field technology to process plastics. It is mainly used in blister packaging, automotive interiors, footwear, and medical consumables, supporting heat sealing and cutting of PVC, APET, PU, and other plastic materials.
Its working principle is based on the 13.56/27.12/40.78MHz international industrial waveband. A high-frequency electric field is generated through a vacuum tube self-excited oscillator, causing frictional heating of the plastic molecules to complete the welding process. A frequency stabilizer and spark suppression circuit ensure processing stability and safety.
The synchronous welding high-frequency machine causes the internal molecules of the plastic to move and rub against each other in the high-frequency electric field between the upper and lower electrodes. Under the pressure of the mold, the desired welding effect is achieved.
