Hydraulic HF Press

HSD-HYD
The working principle of a high-frequency welding machine relies primarily on high-frequency electromagnetic fields. Processed materials (e.g., plastics, leather) undergo molecular polarization in the high-frequency electric field, aligning with the field’s direction.
As the high-frequency electric field reverses direction rapidly, dielectric materials heat up via dielectric loss—generating instant intense heat to melt the material. Finally, the molten material is pressed by a mold to achieve welding or embossing.

 Hansweld Hydraulic High Frequency Welding Machine – High-Pressure HIGH FREQUENCY WELDING MACHINE for Heavy-Duty Industrial Applications

The Hanswend Hydraulic Series is a high-performance HIGH FREQUENCY WELDING MACHINE featuring a hydraulic oil pressure drive system. Unlike conventional pneumatic systems where air is compressible, hydraulic oil is incompressible, delivering exceptionally stable pressure output throughout the entire pressing process. This HF WELDING MACHINE ensures uniform force distribution across large-area molds, resulting in consistent, airtight welds and smooth, burr-free edges on oversized workpieces and thick materials.

Operating at 27.12 MHz with available oil pressures up to 5T -30 tons (30T) , the hydraulic system provides powerful, smooth, and adjustable pressing force, making it the preferred choice for applications where standard pneumatic welding machines fall short. Key applications include:

  • Automotive interior components: sun visors, door panels, floor mats, seat lumbar support air bags, ventilation seat welding, acoustic foam liners, motorcycle helmet liners, and sponge leather cushions

  • Tarpaulins & industrial fabrics: truck tarpaulins, PVC biogas digesters, water reservoirs, PVC trampoline mats, membrane structures, tensile fabric roofs, carports, and outdoor shade sails

  • Inflatable products & rescue equipment: PVC inflatable castles, jump beds, water slides, life jackets, life rafts, inflatable boats, and floating islands requiring high-strength airtight seams with pressure testing up to 0.3MPa

  • Medical & healthcare: blood bags, IV fluid bags, urine bags, ice packs, heat packs, medical identification wristbands, and anti-decubitus mattresses

  • TPU welding & leather goods: TPU airbags, massage chair bladders, artificial leather, genuine leather embossing, phone cases, tablet covers, luggage tags, and handbags

Equipped with NL-5557 spark protection system, high-frequency shielding, precision temperature control, synchronized leveling mechanism for large table platen, and CE certification, the Hanswend Hydraulic HF WELDING MACHINE delivers powerful, stable, and reliable performance for heavy-duty, high-volume industrial production.
