In recent years, with the rapid development of the plastics industry and general engineering plastics and continuously improve the strength and accuracy in other aspects of the application of plastic products are expanding, such as: household appliances, instruments, construction equipment, automotive, Japan with hardware and other fields, the proportion of plastic products are rapidly increasing. In this context, the development of plastic mold slowly accelerates, more and more plastic mold supplier. As the saying goes in order to develop certain knowledge is bound to understand in the industry, or want to make big money is very difficult. Harbin is the same plastic mold industry brick mold, plastic mold supplier in order to get more profits, in addition to the development of technology, but also need to understand the knowledge of certain plastic molds and plastic mold products. Explain to everyone here, our daily production, life used to a variety of tools and products, large base, body shell, as small as a germ-head screws, buttons and a variety of household appliances, machine housings, all has a close relationship with the mold. Shape of the mold determines the shape of these products, processing quality and accuracy of the mold will determine the quality of these products. Because a variety of different products, materials, appearance, size and purpose, the mold into the casting mold, forging, die casting mold, stamping mold and other non-plastic mold and plastic mold. Affect the surface condition of the polishing process cement brick mold steel, the surface due to the heat, stress or other factors damage broken cutting machining process, the improper cutting parameters will affect the polishing effect. EDM surface than the surface after general machining or grinding harder after heat treatment, machining and therefore should be adopted before the end of EDM precision gage EDM dressing, otherwise the surface will form a hardened layer. If EDM finishing gage inappropriate choice of the heat-affected layer of depth up to 0.4mm. A thin layer of hardened hardness than the matrix hardness Baoding brick mold must be removed. So it is best to increase a rough grinding, the elimination of damaged surface layer, constitute a mean rough metal surface, providing a good foundation for polishing.
