What are the technical concepts of forgings?

Forging forming technology refers to the part forming technology that can be used almost without any treatment after the part is formed, also known as near net forming technology.

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

According to the metal flow conditions in the casting process: semi-closed, closed and open forging forming process; according to the forming temperature: superplasticity, room temperature, medium temperature, high temperature forging forming, etc.; according to the forming technology is divided into: split casting, isothermal casting, double dynamic casting, compound forming, warm precision forging, hot precision forging and cold precision forging. Forging technology according to the division of the forming process has become a customary classification of production methods.

Die forging is a new technology developed on the basis of general molds and requires almost no cutting. It is some parts of direct casting parts. These parts need to be cut to meet the accuracy requirements of the past, or only need to leave a few on the ground. Therefore, the use of die forging technology requirements for die forging related links put forward more stringent technical requirements, such as: control the quality and surface of the blank; reasonable planning of the bottle embryo; less blank without oxidation heating; heating specifications and control cooling specifications; control mold manufacturing and use accuracy; select the appropriate lubrication and cooling conditions.

Die forging has significant advantages, can save metal and reduce cutting man-hours. However, due to the strengthening of the relevant links of die forging, part of the cost will be added. Therefore, according to the general economic indicators of product parts production and the special requirements of part structure and function, the general consideration should be given to whether to select the die forging process for a specific product.
