Optimization of Plastics Injection Molding Processing Parameters Based on the Minimization of Sink Marks

To minimize the sink marks on the injection molded parts of automobile hand brake cornice,the forming processing in mold cavity was analyzed with Moldflow software.Based on the minimization of the product surface sink index,the reasonable gate location,gates numbers and optimization parameters such as mold temperature and melt temperature were gotten.Based on these optimization parameters,the cycle of mould development is shortened,and the quality of products and the competitive ability of company are improved.
