The stainless steel forgings of precision plastic injection molding manufacturers can be divided into different types according to the moving method of the whole processing material. The most common types are free forging and die forging. The former mainly uses the impact force or large pressure formed by the artificial machine to promote the shape change of stainless steel metal materials between the two anvil blocks, so as to obtain the required parts. Of course, it can also be divided into manual equipment and manual use according to the size and requirements of different companies. The latter mainly promotes the large extrusion of some stainless steel plates in some moulds through open close forging, thus changing their own shape

The stainless steel manufactured by injection molding manufacturers can also be divided into three categories according to the effect of temperature. The most common ones are hot forging and cold forging, and the one in the middle is warm forging. These methods can be selected according to different requirements of relevant industries. Sometimes, two methods can be combined to play a more accurate role in promoting various shape changes of stainless steel plates according to certain specifications and standards. As long as they can be further improved, these methods can be used for forging

Grinding and polishing have strong flatness, bright labor intensity, and serious pollution. It is difficult for injection molding manufacturers to process complex parts of customized molds, with low gloss and high investment costs. Small and medium-sized products and complex parts cannot be processed. The gloss of the whole product is inconsistent, and the gloss maintenance time is not long

Chemical polishing requires less investment, complex parts can be polished, with high efficiency, fast speed, and insufficient glossiness. The polishing liquid needs to be heated, and there is gas leakage, which requires complicated products with ventilation equipment. Products with low glossiness requirements can be processed in small batches, which is cost-effective. Electrochemical polishing achieves mirror luster, which can be maintained for a long time, with stable process, less pollution, low cost, strong anti pollution ability and large one-time investment. Complex parts must be fitted with tools and auxiliary electrodes. Large scale production requires cooling high, medium and small parts, keeping the mirror bright for a long time, stable process, convenient use, and can be widely used
