The working principle of seam welded machie:Mainly use high-frequency equipment,high-voltage rectification,self-excited high-frequency tube oscillation,instantaneously generate high-frequency electromagnetic field,use processed PVC,TPU, EVA,PU and other plastic materials in the high-frequency electromagnetic field.The internal molecules generate polarization heat,and a certain pressure makes the plastic and plastic products that need heat sealing and welding achieve the effect of fusion sealing.

Seam welded machine in our factory: It is mainly used for welding of PU/PVC/TPU materia and automatically welds plastic materials of different shapes and cuts the edges at the same time.

We use precision seam welded machine developed by high-end technicians,The seam joints of the raincoats we produce are heat-pressed by a heat sealing process, which can be 100% waterproof.And the seams will look more beautiful,Raincoats using the heat-sealing process are very popular in the European market. According to customer feedback: our heat-sealing process will not crack or look unattractive, and the workmanship is fine, which is very popular among consumers.

We have many seam welded machines in the factory,the purpose is to meet the production and supply needs.Our sample room also has a seam welded machine to ensure that the samples can be produced in a short time. If you have your own design and want to use the heat sealing process, please feel free to ask us.
