The Multiple Functions of the Mould Steel
As far as we know, the mould is a primary machining tool in many industrial sectors, such as machinery manufacturing, radio meter and electric appliance. What’s more, the quality of the mould has a direct effect on the production cost, accurate output and the quality of the processing technology. Thus, it is quite clear that the quality of the mould should be concerned by people. In recent years people make their effort to research the factors that determine its quality. They find that apart from the proper structure design and processing accuracy the quality of a mould mainly depends on its material and the way of heat treatment.
Owing to the multiple functions of the mould, the working conditions for the moulds are quite different. Therefore, the material for the mould has a broad range of choice. Among so many materials, the mould steel is the most widely used by the mould. Just as its name implies, the so-called mould steel refers to a type of tool steels that are used to make the moulds, such as the cold-punching mould, hot-forging die and so on. According to the functions of the mould steel, it can be grouped into three types, namely cold-working type, hot-working type and plastic type. Now the following article will introduce them in detail. Read the rest of this entry »
