Tarpaulin manufacturers introduce the molding process of tarpaulin

According to tarpaulin manufacturers, when producing tarpaulins, the processes adopted are different according to the types of tarpaulins. As far as tarpaulins are concerned, its molding process is mainly: 1. , when the negative and male molds are in fast contact, change to slow speed. The operation method of fast first and then slow is conducive to shortening non-production time, preventing mold scratches, and preventing raw materials in the mold groove from being carried out by air due to fast mold closing, and even The insert is displaced and the forming rod is destroyed. 2. When molding thermosetting plastics, moisture and low molecular substances are often released. In order to eliminate these low molecular substances, volatile substances and air in the mold, the pressure can be released after the plastic reaction in the mold cavity of the plastic mold has been carried out for an appropriate time. Loosen the mold to vent for a short time. Curing is to keep for a period of time at the molding temperature, so that the polycondensation reaction of the resin can reach the required degree of crosslinking, so that the product can have the required physical and mechanical properties. 3. Demoulding is usually done by ejector rods, and mold blowing. After demolding, compressed air is usually used to blow the mold cavity and the mold surface of the mold.
