How do you determine the appropriate degree of metal deformation in the forging process?

How do you determine the appropriate degree of metal deformation in the forging process?

China Forging Talent Network: After punching, the final dimensions of forgings typically change—specifically, the height dimension tends to shrink, while the radial dimension expands. The forging ratio is a key measure of the degree of metal deformation during the forging process, calculated as the ratio of the metal’s cross-sectional area before and after deformation. Depending on the specific forging operation, the method for determining the forging ratio varies. 1. **Drawing-forge Ratio**: This is the ratio of the cross-sectional area before drawing to the area after drawing. 2. **Upsetting-forge Ratio**: This refers to the ratio of the cross-sectional area after upsetting to the area before upsetting. As the forging ratio increases, internal porosity is compacted, and the as-cast dendritic structure is broken down, significantly enhancing both the longitudinal and transverse mechanical properties of the forged part.

Safety Operating Procedures for Forging and Pressing Machines

Safety Operating Procedures for Forging and Pressing Machines

Forging and pressing machinery refers to the mechanical equipment used in forging and pressing processes for shaping and separating materials. These machines include forming tools such as forging hammers, mechanical presses, hydraulic presses, screw presses, and flat-die forging machines, as well as auxiliary equipment like decoilers, straighteners, shears, and forging manipulators. Since forging and pressing machinery is primarily used for metal forming, it is also commonly known as metal-forming machine tools. The fundamental characteristic of forging and pressing machinery is its ability to apply significant pressure to shape metals—making it typically heavy-duty equipment. To ensure both operational safety and the protection of personnel, these machines are often equipped with robust safety devices. **Forging Press Safety Operating Procedures:** 1. Inspect the die to ensure it is free from cracks, properly installed, and securely fastened.

Analysis of the Current Status and Future Prospects of the Domestic Forging and Pressing Machine Market

Analysis of the Current Status and Future Prospects of the Domestic Forging and Pressing Machine Market

With the rapid development of China’s automotive, high-speed rail, wind power, and light industry sectors, the demand for and production volume of forged and pressed components have been steadily increasing. The forging industry is now experiencing an urgent need for high-precision forging presses, presenting unprecedented growth opportunities for the sector. After years of technological advancement and innovation, China’s domestic forging press market has established a well-rounded, strategically sound development plan—focusing on enhancing product quality while simultaneously controlling manufacturing costs and ramping up marketing efforts. As the industry moves forward, it’s crucial for domestic manufacturers to seize these opportunities by shifting from a purely production-oriented model toward a more service-driven approach, while also investing in cutting-edge, automated high-end forging press solutions. This strategic pivot will not only help them solidify their position in the domestic market but also pave the way for expanding into international markets. **I.

The applications of magnesium alloy forging materials are expected to expand.

The applications of magnesium alloy forging materials are expected to expand.

The applications of magnesium alloy forging materials are expected to expand, but cost remains a significant bottleneck. As a result, the industry is actively pushing forward the development of new technologies to reduce expenses. One such innovation is the low-temperature magnesium alloy forging technology jointly developed by the Sustainable Materials Research Division of Japan's National Institute of Advanced Industrial Science and Technology (AIST), and Miyamoto Industry Co., Ltd. (headquartered in Tokyo). This technology offers several key benefits by lowering the forging temperature. Specifically, it involves pre-organizing and precisely controlling the structure of the forging material, which reduces the crystal grain size to below 10 μm. The process then employs servo stamping at relatively low temperatures—below 200°C—for efficient forging.

Analysis Report on the Transformation and Upgrading of China's Large Forging Industry

Analysis Report on the Transformation and Upgrading of China's Large Forging Industry

Wuxi's machinery and equipment industry has once again achieved a significant milestone—China Forging Talent Network learned that the world's largest-tonnage hydraulic press recently rolled off the production line and began operation in the Jiangyin Port Industrial Development Zone. This "giant" was independently developed and manufactured by Jiangsu Guoguang Heavy Machinery Co., Ltd., reaching an impressive capacity of 19,500 tons—surpassing the previous record of 18,500 tons held by CITIC Heavy Industries. Cheng Xianbiao, a researcher at China National Research Institute of Heavy Machinery Co., Ltd., who participated in the R&D and design process, told reporters that this massive press is capable of seamlessly forging heavy-duty components required for applications such as aircraft carrier decks, large ball valves, and nuclear power facilities. Inside Guoguang Heavy Machinery's production workshop, this "colossus" of a hydraulic press stands ready to deliver unparalleled performance.
