Types Of Plastic Seals

The main material of plastic seals is plastic, and the production cost is much cheaper than steel wire seals and high security seals, so many customers choose to use plastic seals. In addition, plastics have good plasticity and can be used for mass production of mold injection molding. The appearance of plastic seals is similar. , but the internal structure is different. It can be mainly divided into two categories: one-shot injection molding and injection welding. The price of one-shot injection molding products is relatively low, and the price varies with the size of the style. High, the head of the one-shot injection-molded seal has an inverted plastic buckle during injection molding, which is also where the seal is used to snap. The plastic seal of injection molding welding is taken off from the injection molding machine, assembled with steel sheets, and then covered with hot-melt crimping. After the buckle, if the seal is to be pulled out after passing through, it will be pulled upside down by the stainless steel sheet, and the seal will be broken by dead pulling.
