High-Frequency Rainwear Making Machine is also known as high-frequency raincoat welding machine and radio frequency raincoat making machine, which is a high-frequency device, whose self-excited oscillation tube can generate a high-frequency electromagnetic field. Placing the thermoplastic materials in the high-frequency electromagnetic field between the upper and low electrode. When those molecules within materials are polarized and produce heat automatically by fierce movement and friction, it will be welded with the pressure of the molds. The high-frequency raincoat welding machine does not require external heating only the heating generated by the high frequency field. Besides, it also equipped with the anti-spark circuit to protect tools and raw materials.
