Many details, such as bosses, ribs, threads, can be formed in a single injection molding operation.
The traditional mode of moulding plastics is earlier to moulding plastics the chamber and shaping, then to moulding plastics the intracavity and fill the raw materials that melt the state, carries out whole cooling to moulding plastics the chamber again for the product shaping. However, in the process of cooling and solidifying the raw material, the material may shrink, so an open shrinkage compensation opening is often left at the upper part of the mold, but the traditional shrinkage compensation opening is small, and the wall surface of the product to be molded is often far away from the compensation position, so that the product is scrapped due to the opening and the crack formed on the side wall part of the product, especially some thin-wall products, the injection molding rate of which is low. And if the side wall of the product is too thin and too long during injection molding, the injection molding raw material can not reach the molding position well, bubbles or crevasses are easy to generate during workpiece molding, and multiple injection molding is needed to prevent bubbles from occurring inside the workpiece.
