15-year precision mould making

    The structure of precision plastic mold components with various shapes and sizes. Below by appropriate jersey for you analyze the structure of precision plastic mold components processing characteristics, preferred to analyze which surface is made of the parts, because the surface shape is to choose the basic factors of processing method. Precision plastic mold components are composed of basic and special surface. Basic surface of internal and external cylindrical surface, conical surface and plane and so on, the special surface are mainly helicoid, involute forming surface and other surface. Cylindrical surface, for example, are usually by turning and grinding processing, while more of the inner hole through drilling, expanding, reaming, boring and grinding processing method. Secondly, the size of the surface to process has important influence, hole, for example, within large holes and holes, deep hole and shallow holes in the process have different features.        

   Therefore, in the analysis of the structure of the precision plastic mold components, not only pay attention to the parts of each constitute the characteristics of the surface itself, but also pay attention to the different combinations of these surfaces. It is these characteristics in the structure of precision plastic mold components of the combination . For example, cylindrical surface, can be composed of plate and ring parts, also can constitute a sleeve parts. For the sleeve parts, but both general shaft sleeve, can also be a complex thin-walled sleeve shape. The different structure of precision plastic mold parts tend to have larger differences in technology.
