Plastic Products Manufacture

Today in the manufacture of plastic products used different structural types of molds. Each of these types of stands, depending on how the production molds were made drawing up the nest and loading chamber. Manufacture of molds – a necessary element of any production of plastic products, as they cast all its parts, or just the finished product. That is why the manufacture of molds is very important stage, because of their quality are dependent appearance and characteristics of the finished product. The main element of any mold is the matrix corresponding to a polymer for imparting the desired shape. It combines two basic element: the actual shape of the cavity and the loading chamber.

Manufacture of molds suggests that, for the manufacture of different complexity and different materials needed to apply certain shape design cavities (or decorate nests). The first type – open. In the manufacture of molds is not creating a separate loading chamber, and it is used as the decoration itself nest. As a result, the accuracy of the casting in such a mold gets low, so it can only be used for the manufacture of simple configuration and low thickness. Opposed to it – closed type. Manufacture of molds here implies Department of the loading chamber, however, it is thus a direct continuation of the issuing slot.

Manufacture of molds of this type is necessary for the production of products of complex configurations, which require high precision casting. For them, apply any plastics, including fiber. The only requirement – they must have low turnover. There is also another type – a semi-closed. It differs in that the matrix and punch made extractor edge (also called this type of drawing up the nest with overflow). Manufacture of molds such construction is used more often than others, it provides accurate casting products of different configuration. The production used powdered and fibrous plastic low yield.
