In the field of high-end equipment manufacturing, the precision casting of key components has been a bottleneck that restricts the improvement of product performance. Whether it is the complex flow channel of ship pumps and valves, the high temperature resistant structure of aerospace power components, or the precision cavity of industrial machinery, the traditional casting process is faced with common challenges such as long mold development cycle, high cost, and difficulties in molding complex structures. Beijing SANDI Technology Co., Ltd (referred to as \"SANDI Technology\") unique 3DP + SLS composite sand casting technology, is a series of industry challenges for this breakthrough solution.<\/p>\n\n\n\n

The process creatively combines the advantages of two 3D printing technologies: the 3DP process for making high-precision outer molds, and the SLS process for molding complex inner cavities or fine piping cores. This combination of technologies not only realizes the structural complexity that is hard to reach by traditional processes, but also improves the strength of the sand core to 4-6MPa, which is much higher than the 1.5-2.5MPa level of traditional processes. In practical applications, this process has been successfully used in the high-precision manufacturing of complex structural parts for ship pumps and valves, aerospace power components, etc.<\/p>\n\n\n\n

Recently, Xinxin Casting, a subsidiary of SANDI Technology, successfully delivered a batch of highly difficult cast steel pump bodies for an industrial machinery customer. The structure of this batch of pump body is extremely complex, including several narrow inner cavities of only 2-3 millimeters in width, and need to withstand a casting temperature of up to 1750\u00b0C. The traditional casting method requires a production cycle of nearly 60 days. The traditional casting method requires nearly 60 days of production cycle, while the use of 3DP + SLS composite process, Xinxin casting only 20 days to complete the delivery of 10 products, in order to ensure the quality of the same time, the efficiency of the traditional process has increased by 3 times.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Previously, the technical reliability of the composite process has been verified in the aerospace field. The aircraft engine parts manufactured by SANDI Technology using this process have been successfully selected as a typical application list of additive manufacturing by the Ministry of Industry and Information Technology. While solving the complex oil circuit sand core printing problems, the process effectively overcomes the deformation of the traditional sand mold in the temperature return process, providing a new technical path for high-precision casting.<\/p>\n\n\n

\n
\"\"<\/figure><\/div>\n\n\n

Supporting this innovative process is a system of 3D printing equipment independently developed by SANDI Technology. Among them.3DP Sand Printer<\/a>The series is equipped with 400dpi ultra-fine printhead and precision motion control system, which can realize the highest printing accuracy of \u00b10.3mm. Through piezoelectric inkjet technology + high-resolution inkjet system + special binder, it realizes high-speed, precise and integrated molding of complex structural parts.<\/p>\n\n\n\n

The sand pattern printed by this series of equipment is characterized by high precision and high strength, which is suitable for the manufacture of complex pipelines and oil pipeline structures. With stable and reliable operation, this series of equipment has provided solutions for more than a hundred domestic and foreign customers, and has been highly recognized.<\/p>\n\n\n\n
