pvc welding machine for stretch ceilings ,this machine is we design for Russian customer ,for electrode could change to 650mm length also cost is no high ,one economic type of machine . Also could change machine to singale head for request . Timing continued electrical control, especially for difficult alignment products welding,also can choose pneumatic devices according to the needs of pressure. High frequency welding machine designs the principles of toggle leverage. PVC welding enables uniform pressure, high frequency machine severity of head pressure can be adjusted to match the needs of high-frequency welding depth. High frequency (HF) welding method (otherwise known as radio frequency ) is usually often applied whenever PVC and PU products have to be welded. Common products manufactured with HF welding method are tarpaulins, tents, ceilings, advertising outdoor banners, waterbeds, inflatable boats, drip and blood bags, tensile structures, conveyor belts, rain clothing, etc. SPECIFICATION FOR STRETCH CEILING FILM WELDING MACHINE Model: GP3.2-K5/GP3.2-K9 Usage power: 220V 50-60Hz HF Power: 3200W Oscillation tube: 7T62 Max pressure: About 180kg Pressure mode : Pneumatic or Pedal way Max distance of electrodes: 130mm Working plate: 380*700mm Electode holder: Could be 650mm length Temperature Range: 0-300 Degree Adjustable Welding time: 0.01-9.99 seconds Adjustable Production : Equal or less 5000 times / 8H Net weight of machine : About 350kg
