steven's blog for plastic mold and plastic molding

We must first know some of the basic injection mold knowledge before talking about plastic mold steel, first of all, the classification of plastic mold are generally is on the length of plastic mold by 5 grades, over a million times grade 1;grade 2:500,000-100 million;grade 3 :from 300,000 to 500,000;grade4:from 100,000 to 300,000, grade 5: 10 million below Grade1 and 2 need mold stell hardness after heat-treatment reaching around HRC50 , or plastic which is easy to wear, could violate the tolerance, so we should select steel heat afetr treatment showing better performance, but also at high hardness of the state has good cutting performance, of course, There are other considerations. I seldom come into contact with Chinese-made plastic mold steel, it can only introduce commonly used in the Pearl River Delta for imported raw materials. Usually chosen in Sweden 8407, S136, U.S. 420, H13, Europe, 2316,2344,083, or Japan SKD61, DC53 (the original mold for the metal material, the use of s

First step: to conduct a feasibility analysis for the plastic mold design products ,taking computer chassis as an example, the first drawings of the components make use of design software products for group analysis of legislation, that is what our work of plans to ensure that plastic mold design drawings prior to the correctness of each product, on the other hand, we can be familiar with the various components in the entire chassis to know the importance of the key size, which in the plastic mold design is very good. Step two: after Product analysis job bing carried out, we will analyze what kind of plastic mold structure, and product scheduling process to determine the work of workers and to make use of design software products start at the beginning of Products general follow-up project forward from the start, such as one in five Product requirements processes, and stamping is completed at the beginning of Products Products Drawings from the start to the four projects, three project
