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. Take tarpaulin as an example, its molding process is mainly as follows: 1. When clamping the mold, use fast first, wait for the negative, and change to slow when the male mold is in quick contact. The operation method of first fast and slow is beneficial to shorten non-production time, prevent mold scratches, and avoid raw materials in the mold groove due to mold closing It is carried out by the air too fast, 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, volatiles and air in the mold, the pressure can be relieved after the plastic reaction in the plastic mold cavity has progressed to a suitable time. Loose mold exhaust for a short time. Curing is to keep the molding temperature for a period of time, so that the polycondensation reaction of the resin reaches the required degree of crosslinking, and the product can have the required physical and mechanical properties. 3. Demoulding is usually done by ejector rods, and the mould is blown. After demolding, the mould cavity and the mould surface of the mould are usually blown with compressed air.
