This technology was developed on the basis of conventional forging processes and represents an integrated application that combines computer information technology, new energy sources, and advanced materials. At this stage, precision forging technology is primarily used for producing precision-forged components and refined blanks. It offers distinct advantages, including low cost, high efficiency, energy conservation and environmental friendliness, and superior dimensional accuracy. Depending on the forming speed, this process can be categorized into several types, such as high-speed precision forging, standard precision forging, and low-speed precision forging.
Based on the metal flow conditions during forging, precision forging processes are classified as semi-closed, closed, and open die forging; according to forming temperature, they are categorized as superplastic, room-temperature, medium-temperature, and high-temperature precision forging; and based on forming techniques, they include split forging, isothermal forging, dual-dynamic forging, composite forming, warm precision forging, hot precision forging, and cold precision forging. The classification of precision forging technologies by forming process has become a conventional method used in production.
Precision die forging is a new technology developed on the basis of conventional die forging, requiring virtually no machining. It involves directly forging certain components that previously had to be machined to meet precision requirements, or that now only require a minimal amount of subsequent machining. Consequently, the application of precision die-forging technology imposes stricter technical requirements on the various stages of the forging process, including: controlling the quality and surface finish of the billet; designing the billet geometry appropriately; minimizing oxidation during heating by using billets with reduced surface area; specifying and controlling heating and cooling parameters; ensuring the manufacturing and operational accuracy of the dies; and selecting appropriate lubrication and cooling conditions.
Precision die forging offers significant advantages, including material savings and reduced machining time. However, the enhanced process steps involved in precision die forging lead to higher costs. Therefore, the decision to adopt precision die forging for a particular product should be based on a comprehensive assessment of overall economic performance metrics for finished-part production, as well as the specific structural and performance requirements of the part.
