Trusted by Manufacturers Worldwide

High frequency welding machines utilize high frequency electromagnetic fields (typically 27.12MHz or 40.68MHz) to generate frictional heat in the molecules of polar materials such as PVC and TPU, and then fuse them under pressure. It is suitable for sealing, welding or embossing, without the need for glue or stitching, achieving high-strength bonding.

High frequency welding machines are specially designed for thermoplastic materials such as PVC, PU, TPET, and EVA, and can also handle coated fabrics and inflatable products. If you have any special material requirements, please provide samples and we will test the compatibility for you.

Yes. Our machines have passed CE and ISO certifications, hold 23 patents, and comply with FCC electromagnetic interference limits, ensuring safe use in regions such as the European Union and North America. Each device comes with a compliance certificate.

Our normal high frequency welding machine’s electrical voltage is 380V 50hz. If the power supply voltage in your country is different from ours, you can customize the voltage from our factory. For instance, the voltages of different countries such as the United States using three-phase 480V 60hz and Mexico using three-phase 220V 60hz can all be customized.
