In 2026, pumpeller manufacturing is shifting from the traditional "experience-based pouring + repeated trial production" to digital casting driven by Casting Simulation,al Solidification, andect Prediction. A recent in Scientific Reports used ProCAST to conduct finite simulation of six pouring and schemes for CF8M stainless steel centrifugal pump impellers, focusing on the analysis of temperature fields, cooling rates, solidification sequences, and shrinkage porosity and shrinkage cavities. The study shows that the impeller hub and the blade-to-hub connection zone are typical hot spots and high-risk areas for shrinkage porosity. By adjusting the runner, riser, mold inclination angle, and venting structure, the final solidification zone can gradually directed toward the riser. The optimized scheme adopts a 20° mold inclination angle and adds a venting design, significantly improving directional solidification and internal density. Jiangsu Haifa Machinery Manufacturing Co., Ltd.www.jslgpump.com) can this technical route to the manufacturing of API 610 OH, BB1–BB5, VS series, and high-pressure multistage pump impellers. For CF8M, CF3M, duplex steel 2205, super duplex steel 2507, and high-alloy corrosion-resistant impellers, a digital manufacturing process of "3D CAD—ProCAST casting simulation—Shrinkage Porosity Prediction—Niyama Criterion—process validation" can be established to predict the locations of hot spots, gas porosity, inclusions, and shrinkage porosity before pouring, reducing the number of trial-and-error iterations and improving batch consistency. Research on additive manufacturing in 2026 shows that Reverse Engineering, 3D Scanning, Additive Manufacturing are to be used for the remanufacturing of pump impeller spare parts but geometric deviation, post-processing, and quality control still directly affect the final hydraulic performance. Forsu Haifa, traditional precision casting and digital simulation remain an important foundation for the large-scale manufacturing of complex impellers for API 610 pumps. In the future, Digital Cast Twin, AI Casting Optimization, and CT/NDT inspection can be further integrated to shift casting defect control from "post-event detection" to "pre-pouring prediction."
