High frequency heat sealing method of rainproof tarpaulin

In the process of producing rainproof tarpaulins, tarpaulins are spliced, especially the production of large tarpaulins, and splicing is almost an indispensable process. However, for the splicing of rain-proof tarpaulins, the principle of high-frequency thermal energy heat sealing is generally used. During the friction heat sealing process of the vibrating rail, the upper workpiece orbits at a fixed speed. When moving, heat energy will be generated, so that the heat joint of the two plastic parts reaches the melting point. Once the plastic parts begin to melt and the movement stops, the heat joint parts of the two workpieces will solidify and be firmly connected. In addition, the clamping force is small, the deformation of the workpiece is small, the high-frequency instantaneous heat sealing, heating, and the heat sealing is successful through one-time high-frequency welding. When our company buys rain-proof tarpaulins, we take the practicality as the main reference factor while considering the price factor.
