Automatic High Frequency PVC PU Welding Machine for PVC_PU_TUP Membrane Radio Frequency Welding of PVC PU Tarpaulin H.F Welding

Automatic High Frequency PVC PU Welding Machine

Automatic High Frequency PVC PU Welding Machine

The most important factors influence Automatic High Frequency PVC PU Welding Machine: #1: electrical power #2: pressure applied #3: welding time #4: cooling time, Finding the optimal process parameters will depends on your specific equipment, the materials involve and the specific geometries including thickness and area to be welded, achieving optimal results is often an experimental process guided by experience, as a guiding rule, the thicker material and focus on short welding times you need, the stronger electrical power you need

Machine Description

01: Application

High Frequency PVC PU Welding Machine is the case of radio frequency welding (R.F/H.F bonding) for PVC PU TPU Membrane, the welding heat is produced by molecular oscillations (Friction heat) directly in the PVC, PU material to be welded, oscillation tube transmits the high frequency oscillation usually 27.12mhz and pressure to the welding tool (electrode), the pressed surface is the jointing area, where the molecules inside the PVC, PU material to start to move and generate heat which softens the material, No heat is applied from outside, it is generated inside the PVC,PU, After cooling the welded surface at a constant pressure, the material is fused and welding is ready, the weld joint can be as strong or even stronger that the surrounding material, high frequency welding is suitable for welding/making/sealing/bonding the membrane structure cloth/Film made of PVC, PU, TPU, PETG, other PET Family sheets. Even or Nylon, Textile cloth treated by High frequency (H.F/R.F) reactive Poly material, or adhesive glue Tarpaulin, Canvas, such as stretched ceiling, tents, inflatable pool/boat, truck covers, Biogas balloon/bladder, oil fence, advertising banners, Film screen, canopy, awning, marquee, curtain, swimming ring, air floating, inflatable water trampoline, inflatable water roller, inflatable castle, inflatable slides, inflatable water slides, inflatable water park, inflatable pool slides, inflatable bouncy castle, inflatable jump bed, advertising flexible banner
