In 2026, China’s casting, forging and machining industry continues to advance toward high-end, intelligent and green transformation. Leveraging core technological breakthroughs in Process Design, the industry integrates the full industrial chain advantages of casting, forging and precision machining. It promotes the coordinated upgrading of segmented fields includingSteel Investment Casting, Ductile Iron Sand Casting, Aluminum Casting, Forging and Machining, accurately meeting the high-standard demands of downstream markets such as new energy, construction machinery, aerospace and high-end equipment. This drives the quality and efficiency improvement of China’s basic component manufacturing industry and helps break through technical bottlenecks.
As a core process for manufacturing high-end precision parts, Steel Investment Casting is the preferred solution for core components of high-end equipment thanks to its outstanding advantages of high dimensional accuracy, superior surface finish and dense material structure. Compared with traditional casting processes, it enables integrated forming of complex special-shaped structural parts and effectively avoids performance defects caused by welding and splicing. It is widely applied in key fields such as precision hydraulic components, aerospace parts and fluid control valves. With process optimization and the popularization of intelligent equipment, large-scale and standardized production of steel investment casting has been realized in the industry, greatly reducing defects such as porosity and shrinkage cavity of castings. The product stability and international compatibility continue to improve, filling multiple gaps in the domestic localization of high-end precision castings.
Ductile Iron Sand Casting maintains an irreplaceable industrial status in the heavy-duty industry. Ductile iron features excellent mechanical properties including high strength, high toughness, wear resistance and vibration resistance, perfectly adapting to the heavy-duty working conditions of construction machinery, rail transit and heavy machinery. Supported by upgraded intelligent production lines for sand casting, enterprises optimize core parameters such as sand ratio, pouring temperature and cooling rate, thoroughly solving the traditional pain points of uneven grain distribution and insufficient strength of sand casting products. Equipped with mature post-processing technologies, the produced ductile iron castings have higher rigidity and longer service life. They continuously provide high-cost-performance and high-reliability basic component support for heavy-duty equipment manufacturing, serving as a core process solution for mass production of industrial heavy-duty parts.
Driven by the lightweight trend of the manufacturing industry, Aluminum Casting has ushered in a window of rapid development. Amid the surging lightweight demands for new energy vehicles, intelligent equipment and 5G communication devices, aluminum castings boast the advantages of light weight, good thermal conductivity, corrosion resistance and easy forming, leading to a year-on-year growth in market demand. Industry enterprises keep upgrading diverse processes including die casting, low-pressure casting and gravity casting, overcoming technical difficulties in the forming of large integrated aluminum alloy castings. This effectively improves the compactness and dimensional accuracy of castings, enabling mass production of new energy vehicle housings, precision instrument brackets, communication heat dissipation components and other products. It conforms to the core development trend of lightweight and energy-saving equipment and has become a core track for industrial growth.
In addition to various casting technologies, Forging is the core process that guarantees the comprehensive mechanical properties of high-end mechanical parts. Through plastic deformation of metal, forging refines internal grains and greatly improves the strength, toughness and fatigue resistance of workpieces, making up for the shortcomings of casting processes in the manufacturing of ultra-high-strength parts. It is widely used in the production of core components such as high-end shafts, gears, wind power parts and military structural parts. At present, the industry is gradually popularizing intelligent die forging and automatic open forging production lines. Combined with digital temperature control and pressure regulation systems, it realizes uniform performance and batch standardization of forged products, completely eliminating the traditional industry problems of inconsistent accuracy and unstable performance of forged parts, and consolidating the quality foundation of high-end heavy-duty components.
A complete closed-loop casting and forging industrial chain relies on the refined empowerment of Machining. All blanks including precision investment castings, ductile iron sand castings, aluminum alloy castings and forged parts require high-precision machining for dimension calibration, surface finishing, hole processing and other refined procedures. At present, the industry has widely adopted CNC machining centers and five-axis linkage processing equipment. Relying on an automatic processing system, it achieves high-precision finish machining of various casting and forging blanks with machining accuracy up to the micron level, fully meeting the stringent requirements of high-end equipment for component tolerance, flatness and compatibility, and realizing high-quality control from blank forming to finished product delivery.
Running through the entire production process, Process Design serves as the core driving force for the upgrading of the whole industrial chain. Leading industry enterprises adopt digital process design systems combined with simulation technology. In the early production stage, they complete full-process planning including casting runner design, forging parameter matching, machining procedure arrangement and cooling forming scheme optimization, so as to predict and avoid problems such as forming defects, stress deformation and insufficient machining allowance in advance. Scientific process design not only significantly improves product yield, shortens production cycles and reduces energy consumption and loss, but also optimizes production schemes according to customized customer requirements. It supports customized production of multi-category, high-precision and cost-effective parts, comprehensively enhancing the core competitiveness of enterprises.
Industry experts state that the 2026 casting, forging and machining industry is phasing out extensive production modes. Centering onProcess Design, the industry builds a full-chain, intelligent and green high-end component manufacturing system by integrating four core forming technologies includingSteel Investment Casting, Ductile Iron Sand Casting, Aluminum Casting and Forging, as well as the refined deep-processing system of Machining. In the future, with continuous technological iteration and expanding demands from the high-end manufacturing industry, China’s casting and forging industry will continue to break through technical barriers, accelerate the domestic substitution of high-end products, and continuously release new vitality for industrial development.
