Plastic covers mold to the case without damaging the workpiece conveniently test batches merits of the quality of products, 500X500 square covers mold, on the covers of construction material performance evaluation, concluded that the "hardness" of such a performance indicator. Essentially individual thought, hardness refers to the ability to resist deformation or rupture of the internal volume of the plastic covers mold surface little. The physical meaning of different hardness tests to the plastic covers mold material is different. Hardness penetration method covers the nominal value is material to resist the pressure of another body-fitting plastic deformation resistance caused; scoring method performance surface hardness section covers material can be broken. In the production of the most common is the static load test injection method, depending on the head shape, covers the information and load size, hardness Brinell hardness, Rockwell hardness, Vickers hardness with the hardness of their utility in different plastic covers mold material. Die enterprises compared with the general industrial products business, quantity, small scale, mostly small and medium enterprises, it is because the vast majority of mold is for a specific user single production, while mold products high technology content, the proportion of labor activation Large, high value-added, long production cycle, thus mold manufacturing industry will have a technology-intensive and capital-intensive, balanced production and enterprise management difficult, to specific users with special dependency and so on. Our plastic covers mold industry market still is in a period of rapid growth, covers mold, mold the future will be large-scale, high-precision, multi-functional complex other direction. We continue to invest in new technological transformation of increasingly sophisticated, more diverse varieties and specifications of the mold. Mold production process is relatively simple, only with vibration platform can be completed using the vibration platform in order to exclude the air in the pores, 500X320 covered ditch covers mold, smooth surface after sufficient guarantees good dry. Plastic covers mold manufacturing is not the end goal, but the end product made by the user program, 600X60 covers mold, mold manufacturer in accordance with the needs of users, for manufacturing a mold and in substantially all cases, products are other manufacturers of injection production. In terms of design, quality plastic covers mold design will be a great impact on the actual production cost of the product, it will affect the production of the injection cycle. Reasonable mold design should take into account water fittings should not be moving in the direction of the operator. 500X320 covers mold covered ditch, covers mold, mold provided by Baoding Guohui Guohui Die Machinery Co. Baoding Guohui Die Machinery Co., Ltd. (www.bdguohui.com) (www.bdguohui.com) strong, credible, in Baoding plastic building materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Guohui mold into the brilliant and you work for a better future!
