According to the actual work experience of Injection Molding Tool Co., Ltd., the following three methods can be used to determine the appearance elements of injection molded parts

① Any plastic products related to household appliances and family life. With the improvement of people's quality of life, the appearance requirements of this kind of plastic products are getting higher and higher, and this kind of plastic products must have the appearance elements of injection molded parts

② There is also a class of plastic products whose surfaces are often in contact with people's hands or skin. The surface of such plastic products should also have the appearance elements of injection molded parts. Otherwise, when people's hands or skin contact or touch the surface of the injection molded parts, they will feel uncomfortable. There are also some surfaces that can be seen by the public, and there should also be appearance elements of injection molded parts. Otherwise, when people see the surface of injection molded parts with various mold structure molding traces, they will have a bad feeling. With these feelings, it will affect the sales of products and the processing price of injection molding tools

When the injection molded parts are installed on some moving and fragile commodities (such as silk, cloth, rubber, etc.), it is not allowed to have mold structure molding marks on the surface of the injection molded parts, because mold structure molding marks will wear these fragile commodities
