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.

reduce costs

- Mould cost reduction: In traditional casting, the cost of instrument panel mould is 700,000-1,000,000 RMB, bumper mould is 350,000-700,000 RMB, and engine parts mould is 150,000-600,000 RMB or even higher, while 3D printing sand mould is low cost, flexible in design modification, and does not require expensive mould manufacturing cost.

- Reduced labor costs: The automation of the 3D printing process reduces the reliance on manual operation and human error, reducing labor costs, such as the 3D printing equipment of SANDI Technology can be operated with only simple training, without the need for a large number of manpower synergies.

- Reduced energy consumption: 3DP printing process 3D printing technology consumes less energy than sand core manufacturing and injection molding equipment. Compared with injection molding, 3DP printing sand molding is through the nozzle spray binder will sand bonding molding, without the need for injection molding like the material for a long time heating and melting and other processes, so the energy consumption is greatly reduced. Compared with 3DP printing sand mold, traditional sand core manufacturing in the hot core box method core, need to make the core box to keep at 200 ℃ -300 ℃, let the core sand shot into the core box, ammonium chloride in the higher temperature and the resin in the free formaldehyde reaction to generate acid, so that the core hardened very quickly, the process of energy consumption. While 3DP printing sand mold process, the sand does not need to be heated to such a high temperature, and the equipment itself is relatively low energy consumption.
