FAQ

Trusted by Manufacturers Worldwide

High frequency welding machines use high frequency electromagnetic fields (typically 27.12 MHz or 40.68 MHz) to generate frictional heat within the molecules of polar materials such as PVC and TPU, then fuse them under pressure. The process requires no glue or stitching, achieving a high-strength, airtight bond — ideal for sealing, welding, and embossing applications.

High frequency welding machines are designed for thermoplastic materials including PVC, PU, TPU, TPET, and EVA, as well as coated fabrics and inflatable products. If you have special material requirements, please send us samples and our engineers will test compatibility for you free of charge.

Yes. Our high frequency welding machines have passed both CE and ISO 9001 certifications, hold 23 patents, and comply with FCC electromagnetic interference limits — ensuring safe, compliant operation in the EU, North America, and other major markets. A full compliance certificate is included with every machine.

Our standard high frequency welding machines are configured for 380V / 50Hz. If your facility uses a different power supply, we can customise the voltage to match — for example, three-phase 480V / 60Hz for the United States or three-phase 220V / 60Hz for Mexico. Please let us know your local requirements when placing your enquiry.

Yes. Our in-house high frequency mold production department crafts custom molds from aluminum alloy or copper to your exact specifications. Simply provide a product design drawing or physical sample, and our engineers will design and manufacture the matching high frequency welding mold for you.

We provide a 12-month warranty on all high frequency welding machines (excluding damage caused by misuse). Technical support is available within 24 hours via email, WhatsApp, or WeChat. All customers also receive long-term free video after-sales service and comprehensive troubleshooting guides.

All standard high frequency welding machines are available from stock. Lead times for customised machines depend on complexity — please contact us for details. Machines are securely packaged in wooden cases and shipped by sea (EXW, FOB, CIF, and DDP terms available). Air freight can also be arranged on request.

Welding TPU with a high frequency welding machine requires the appropriate HF mold. Our factory produces custom molds specifically designed for TPU applications, and we provide free technical support — including step-by-step operating guidance — to all customers who purchase our machines.
