Injection moulding is a relatively new part manufacturing method. It is a manufacturing technology that uses plastic to process parts. The molten plastic is added to the mold under high pressure. The mold is made by an injection molding manufacturer, usually made of steel or aluminum metal, and is precision processed to form the shape of the desired part. Injection molding is widely used to manufacture various types of parts, from very small parts to entire body panels. This is a very fast process used to produce a large number of identical products, from high-density engineering parts to primary consumer goods. Injection molding is usually used for mass production. In the injection molding process, the mold is clamped on the injection molding machine, the molten plastic is injected into the mold cavity, cooled and formed in the mold cavity, and then the upper and lower molds are separated, and the product is ejected from the mold cavity through the injection part. First, the mold is closed again to stop the next injection, and the entire injection process is a cycle stop. They have to go through forging, cutting, heat treatment and other processes. In order to ensure the quality of mold manufacturing and reduce consumption costs, the data should have good ductility, machinability, hardenability, hardenability and grindability, and have less oxidation, decarburization sensitivity and quenching deformation cracking tendency .
The main factors affecting the injection molding mold are: the material characteristics of the injection molding mold, including raw material formulation, raw material quality, etc .; the factors affecting the injection molding mold are also the process performance of the injection molding equipment, including the plasticizing effect, extrusion efficiency, Main machine and auxiliary machine stability etc. The distance between the extrusion die and the shaping die will also affect the injection molding die. The degree of conformity of the injection mold with the actual size, the surface shape and position of the part, and the ideal geometric parameters required by the drawing. The smaller the level value, the higher the accuracy. The larger the value, the greater the error. High machining accuracy means small machining errors and vice versa.
