The prerequisite for the success of plastic molds is mainly reasonable plastic mold design. The design of plastic molds is relatively important, and the same structure can be produced in multiple ways. The structure and processing cost of plastic molds are mainly determined by the method of mold release. Not only that, it also determines the product parting line and the service life of the plastic mold. More importantly, different touch methods and types will determine the appearance of the product. Therefore, after determining the corresponding direction of the mold opening direction of the plastic mold, the appropriate parting line can be selected next to avoid the mold opening direction and the situation of undercutting. Furthermore, the appearance and performance can be improved. Of course, after the mold opening direction is determined, the product's buckle, protrusion and other structures should be designed to be consistent with the mold opening direction to avoid reducing seam lines and help extend the service life of the mold.
Under normal circumstances, if the wall thickness is not uniform, it will cause pores and weld marks, not only that, but also cause the surface of the plastic product to shrink.
