Frequently Asked QuestionsHave questions about our high frequency welding machines, lead times, or custom configurations? Find answers below — or contact our engineers for a personalized recommendation.

These three terms — HF welder, RF welder, and RF welding machine — all refer to exactly the same technology. “HF” stands for High Frequency, and “RF” stands for Radio Frequency. Both describe dielectric welding equipment that generates an electromagnetic field at 27.12 MHz to fuse thermoplastic materials like PVC, TPU, and PU from the inside out. In industrial and export contexts, HF welding machine and RF welding machine are used interchangeably.

Zhenjia manufactures the full range — whether you search for an RF welder, an HF welder, a PVC RF welding machine, or simply a high frequency welder, you are looking for the same product.

A high frequency (HF) welding machine generates an electromagnetic field at 27.12 MHz that causes polar molecules in thermoplastic materials — such as PVC, TPU, and PU — to vibrate rapidly, creating internal heat. This fuses the materials from the inside out, producing a molecular bond stronger than the base material and more consistent than heat sealing or stitching.

Zhenjia high frequency welders are compatible with PVC, TPU, PU, PE, PET, PETG, and APET. If you are unsure whether your material is HF-weldable, send us a sample for a free material welding test — no charge, no commitment.

We manufacture high frequency welding machines from 5KW to 50KW+. The right power depends on your material thickness, welding area, and production speed. Our engineers will recommend the correct model after reviewing your product specifications — at no charge.

We offer 12 months warranty, on-site installation & training, and lifetime technical support. Our service network covers major industrial regions across China, with remote support available globally.

For customers in China, our local service partners provide door-to-door repair within 48–72 hours (depending on location). Overseas, we guide remote troubleshooting or dispatch engineers for critical cases.

Yes. We provide free on-site training covering HF welding machine operation, mold adjustment, basic maintenance, and safety procedures for your production team.

Spare parts — including oscillation tubes, capacitors, and electrodes — can be ordered directly through our sales team. We keep common parts in stock for fast dispatch via international express couriers.
