Recently, Dalian Jiachuang Metal Manufacturing Co., Ltd. (hereinafter referred to as "Jiachuang Metal") has achieved a major technological breakthrough in the field of sand casting. Its independently developed patent technology has successfully solved the manufacturing challenges of OH pump steel casting impellers. According to third-party testing, the comprehensive qualification rate of impellers has increased from the industry average of 85% to 99%, and the production cycle has been shortened by 40%. This achievement not only fills the technical gap in high-end pump castings in Northeast China but also marks the innovative strength of local small and medium-sized enterprises in industrial upgrading.

Recently, Dalian Jiachuang Metal Manufacturing Co., Ltd. (hereinafter "Jiachuang Metal") has made a critical breakthrough in sand casting of steel casting impellers—the core of OH pumps—via independently developed patents.

Recently, Dalian Jiachuang Metal Manufacturing Co., Ltd. specially designed and manufactured 8 impeller products for the well-known domestic joint venture company, EBARA Machinery Zibo Co., Ltd. After undergoing multiple rigorous tests, these products achieved full data compliance and far exceeded expectations in terms of quality. They successfully passed the acceptance inspection and received high praise from the customers, writing a magnificent new chapter in the cooperation between the two parties.

In modern industrial systems, stainless steel impeller castings serve as core components of fluid machinery, playing a vital role in energy conversion and medium transportation. From high-corrosion medium pumps in chemical processes to high-temperature, high-pressure ventilation systems in power generation, and sewage treatment equipment in environmental engineering, these castings ensure efficient, stable, and long-term operation of entire systems through their superior performance. This article systematically explores the key technical aspects and industrial applications of stainless steel impeller castings from dimensions including structural design, material properties, advanced manufacturing processes, diverse applications, and technological development trends.

In modern industry, impellers are playing an important role as key components for power transmission and fluid delivery. The performance of impeller castings for water pumps, fans, and compressors directly determines the operating efficiency and service life of the entire equipment.
