The steps of molding color strip tarpaulin

When the color striped tarpaulin is produced, it is likely to adopt the method of molding. What are the specific steps? Let's find out. The curing process is to keep it at the molding temperature for a period of time, so that the polycondensation reaction of the resin reaches the required degree of cross-linking, so that the product has the required physical and mechanical properties. Curing ends temporarily when demoulding, and then use post-processing to complete the entire curing process. Demoulding is usually done by ejector rods. For products with forming rods or some inserts, special tools should be used to remove the forming rods, etc., and then demolding. After demoulding, the cavity and the mold surface of the mold are usually blown with compressed air. If the fixation on the mold is tight, it can be cleaned with a copper knife or a copper brush, or even a polishing agent brush. In order to further improve the quality of the products, after the thermosetting plastic products are demolded, they are often post-treated at a higher temperature. The post-treatment can make the plastic solidify more completely, while reducing or eliminating the internal stress of the products.
