The edge of the dent in the processing of the SMC mould plastic mold is processed by the plastic mold as a processing technique, and after it is manufactured or completed, it is somewhat inferior. What should the mold company encounter in this situation? The following Hongda Industrial Co., Ltd. will talk about the two more common. 1. Dent. The reasons for the occurrence of dents are: 1) The mold cooling is insufficient, and the lack of cooling time may cause severe deformation. 2) The lack of mold connotation pressure will also present this situation. 3) The thickness of each part of the product is different. In the case of this situation, we will have corresponding treatment methods: reduce the temperature of the barrel and the temperature of the mold, forcibly cool in the local area where the dent is generated, fill the flow side of the dent, and control the difference in the thickness of the planned product. 2. Product whitening. The reason for the occurrence of product whitening is as follows. 1), too large fit pressure. 2), poor mold release. In this case, the overall treatment method: When planning the plastic mold, pay attention to the slope of the demoulding. When manufacturing the mold, make sure that the cavity of the mold is kept bright, and the real-time treatment should reduce the injection pressure immediately. Plastic mold processing is a very complicated and prudent process, which inevitably presents some undesirable phenomena. We hope that we will be cautious in the process of operation. A qualified mold product must be through our hardworking work. The plastic mold processing factory is all In the concentration of occupations, Hongda has a high-tech craftsmanship and has been leading the profession for more than ten years and will continue to create brilliance.
