To solve the problem of dents on the side walls of molded parts, a series of measures need to be taken.
Firstly, it is necessary to inspect the mold to ensure that the gate size and position are correct, as well as the cooling system of the mold is functioning properly. Secondly, it is necessary to adjust the parameters of the injection molding machine appropriately, such as temperature, pressure, speed, etc., to ensure uniform temperature and pressure during the injection molding process and avoid local shrinkage. At the same time, the size and shape of injection molded parts also need to be optimized to reduce sudden changes in wall thickness and the appearance of sharp corners, in order to reduce the risk of local shrinkage. In actual production, some auxiliary methods can also be used, such as adding cooling channels on the mold, using hot runners, etc., to improve the temperature uniformity and stability of the injection molding process, thereby reducing the occurrence of local shrinkage.
Through the above measures, the problem of dents on the side walls of molded parts can be effectively solved, and the quality and performance of the product can be improved.
