The air fluid generated by the operation of the fan first enters the heating component, and the heating component heats the air fluid according to a preset temperature, and the heated hot air heats the upper and lower layers of PVC material through the tuyere outlet, and then the pressure is applied by the pressure wheel. The two layers of material that are heated and melted are welded together.
PVC itself is a thermoplastic material that is easily melted and softened by heat and has excellent processing properties.
