In the field of electric power and energy equipment manufacturing, large castings are facing the double challenge of "both rapid innovation and stable batch production". This kind of "big, fine, difficult" castings are not only huge size, but also on the airtightness, strength and dimensional accuracy has nearly demanding requirements. The traditional manufacturing method is caught in a dilemma: if the pursuit of rapid innovation, the use of wooden mold trial period is shorter (about 40 days), but can not meet the stringent precision requirements of the product, but also can not meet the requirements of mass production of the quality and stability; if the direct opening of the metal mold, it is a huge investment in the early stage (mold costs more than 500,000 yuan), and the design of the high cost of change. This contradiction seriously restricts the iterative speed of power equipment, especially in the current industry to accelerate the green, intelligent transformation of the background, the traditional process has been difficult to meet the market demand for rapid product upgrading.

Faced with the dilemma of rapid innovation and stable batch production, SANDI Technology's3D Casting ProcessIn addition, through the 3DP sand printing to achieve 5-7 days of rapid verification, and then based on the verification data to optimize the metal mold design, not only to ensure the speed of innovation, but also to ensure the quality of the batch production, successfully cracked this industry dilemma.

In the manufacturing of extra-high voltage GIS shells, the traditional process requires 3-4 months of mold trimming trial production cycle, while SANDI Technology adopts 3DP sand printing technology to complete the prototype manufacturing and performance testing in only 5-7 days, and realize instant response to design changes through digital models. After qualified by customer verification, the product is quickly transferred to the mass production stage of metal molds, the overall development cycle is shortened by more than 60%, and the surface quality of the final product reaches the standard of zero defects, and the pinhole degree of the sealing surface is better than Grade 1, and it passes the airtightness test.

In a GIS conductor project, SANDI Technology completed the trial production of the product in only 20 days through the innovative process of 3DP sand mold combined with low-pressure casting, and the electrical conductivity fully meets the standards of a class of castings. After rapid verification of the product immediately transferred to large-scale production, not only to help the customer to win the order share of 80%, but also to achieve a stable mass production capacity of 1500 sets of products per year.

This manufacturing model is a perfect fit for the "many varieties, small batch" production characteristics of the power energy sector. Compared with the automotive industry often hundreds of thousands of pieces of large quantities, power equipment components (such as special transformer components, shells, conductors, etc.) annual demand is often only a few dozen pieces. Traditional casting processes are inefficient and costly in this context. SANDI's solution demonstrates excellent flexibility: 3DP sand casting is used for small orders, eliminating the need for costly mold investments; when demand grows, it can be seamlessly switched to metal mold mass production mode. This flexible production capability empowers power equipment manufacturers to effectively respond to market fluctuations and technology iterations. This kind of full-process service integrating "rapid verification of prototype + mass production" is the core advantage of SANDI Technology that distinguishes it from a single 3D printing service provider. The 3D casting center in Pingdingshan, Henan Province under SANDI Technology is equipped with a complete integrated service capability of "process design + 3D printing + casting + machining and testing", with R&D and scale production capacity of super-large shaped aluminum alloy castings, as well as a professional coating line (with a daily coating capacity of 200 square meters, which meets the strict requirements of the national standard), which can achieve an annual production capacity of high-end aluminum alloy castings, and can be used for the production of high-end aluminum alloy castings. The company can achieve an annual output of 5,000 tons of high-end aluminum alloy parts, providing a solid guarantee for the final quality of complex electric energy castings.

In the future, with the rapid development of the smart grid, electric power energy and other fields, three emperor technology will continue to deepen the innovative application of 3D casting technology, through digital, intelligent means to continuously improve product quality and production efficiency, for the transformation and upgrading of electric power and energy equipment to provide a more powerful impetus to promote the entire industrial ecosystem to the direction of more efficient, greener, smarter, and to help China's manufacturing to high-end, Intelligent direction.

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.

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.

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°C. 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.

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.

Supporting this innovative process is a system of 3D printing equipment independently developed by SANDI Technology. Among them.3DP Sand PrinterThe series is equipped with 400dpi ultra-fine printhead and precision motion control system, which can realize the highest printing accuracy of ±0.3mm. Through piezoelectric inkjet technology + high-resolution inkjet system + special binder, it realizes high-speed, precise and integrated molding of complex structural parts.
