High frequency plastic sealing machine(Hf Plastic Welding Machine) has four working station ,one working station to welding ,second to cut ,rest to take finished products out by mechanical arm. What materials can be HF welded by high frequency welding machine: The material most common in high frequency welding in PVC (something called simply vinyl) and PU (polyurethane). The material can be thick or thin, reinforced or coated. It cab also be plain, coloured or structure/patterned. Polyvinylchlorde (PVC) and polyurethanes (PU) are the most common thermoplastics that are weldabele by HF also it is possbile to perform HF welding on other types of materia inculding naylon, PA, ABS, modified TOP, PETG, but particular attention should be pay on working parameters. HF welding is not suitable for PTFE, polycarbonte, polystyrne, polyethylene or polypropylene. Howeve, a special type of mixed fabrics have been produced recently, which have the capability to…
