　　What are the technical concepts of forgings?

　　Forging forming technology is a part forming technology that can be applied with almost no processing after the bottom of the part is formed, also known as near-net forming technology.

　　This technology is developed on the basis of conventional casting molding technology, and is a technology that integrates the use of computer information technology, new energy sources and new materials. At this stage, forging forming technology is mainly used for forging parts and finishing blanks. Forging forming technology has significant advantages such as low cost, high efficiency, energy saving and environmental protection, and high precision. There are various types of forming processes, divided by forming speed: high-speed forging, general forging, and low-speed forging forming.

　　According to the casting process metal flow conditions prevail: semi-closed, closed and open forging forming process; according to the forming temperature: super plasticity, room temperature, medium temperature, high temperature forging forming, etc.; according to the forming technology is divided into: split casting, isothermal casting, double dynamic casting, composite forming, warm fine forging, hot fine forging and cold fine forging, etc. Forging technology by forming process has become the customary classification method in production.

　　Die forging is a new technology developed on the basis of general tooling, which requires almost no cutting. It is a direct casting of certain parts in parts which need to be cut to meet the accuracy requirements in former times, or only a few ground need to be left. Therefore, the use of die forging technology requires more stringent technical requirements for the relevant aspects of die forging, such as: manipulation of the quality and surface of the blank; reasonable planning of the bottle embryo; fewer blanks without oxidation heating; heating specifications and manipulation of cooling specifications; manipulation of die manufacturing and application accuracy; and selection of suitable lubrication and cooling conditions.

　　Die forging has the significant advantage of saving metal and reducing cutting time. However, due to the strengthening of the relevant aspects of die forging, part of the cost will increase. Therefore, according to the general economic indicators of the production of product parts and the special requirements of the structure and function of the parts, the general consideration of whether to select the die forging process for a specific product.
