Shell casting can produce thin-walled, complex-shaped castings, and the development of the industry is supported by policies
Shell casting is a casting method in which molding sand is mixed with powdered thermosetting resin to make a thin shell mold and cast molten metal to obtain castings.
The production process of shell casting is that the molding sand is mixed with powdered thermosetting resin and placed in the dump bucket, the metal mold is heated, buckled on the dump bucket, the flip bucket makes the mixture fall on the metal mold, the thermosetting resin melts and bonds the molding sand to form a thin shell when it is hot, and a thin shell mold is usually formed by bonding two thin shells to increase the strength of the mold, pouring molten metal into the thin shell mold, and obtaining the casting after cooling and solidification.
Shell casting can be done by pouring molten metal directly into a thin shell mold, or by placing a shell mold into a sand box or a container filled with steel pellets to reinforce the shell mold and then pouring the molten metal. According to the "2024-2028 Shell Casting Industry In-depth Market Research and Investment Strategy Suggestion Report" released by the Xinsijie Industry Research Center, shell casting has the characteristics of low demand for molding sand, high surface quality of castings, high dimensional accuracy of castings, and suitable for mass production, and can manufacture thin-walled and complex-shaped castings.
The shell thickness, structural accuracy, strength and other parameters of the shell casting thin shell mold directly affect the quality of the casting, and the raw material selection and processing technology requirements are high. The molding sand used in the thin shell mold needs to have the advantages of high strength and good heat resistance, usually silica sand and zircon sand; Thermosetting resins generally have the advantages of high strength, good heat resistance, and good dimensional stability, and phenolic resins are usually used in the manufacture of thin-shell molds. These materials are combined to meet the requirements of heat resistance and damage resistance of thin shell molds.
Shell casting was developed in Germany in the 40s of the 20th century, and can be used to produce bearings, pump bodies, valve bodies, wheel hubs, engine blocks and other parts at this stage, which are widely used in industrial equipment, automobiles, agricultural machinery, aerospace and other fields. However, shell casting also has disadvantages, such as the high cost of resin materials, the decomposition of resin metal at high temperature to produce irritating gas, etc., and the application is limited.
Casting is an important metal forming process, the mainland as an industrial power, the development of the casting industry chain is perfect, while its technical process is still upgrading, shell casting related research results are still increasing, the invention patents in the past five years mainly include Chengdu Aitan Technology Co., Ltd. "vacuum and pressure combined shell casting device", Sichuan Dujiang Casting Co., Ltd. "a coated sand shell casting device", Baoding Lenovo Casting Co., Ltd. "coated sand shell casting mold and process", Wuxi Yelong Precision Machinery Co., Ltd.'s "a cold core shell casting process for turbine shells" and so on.
The National Development and Reform Commission revised and released the new version of the "Industrial Structure Adjustment Guidance Catalogue (2024 Edition)" officially implemented on February 1, 2024, and encouraged projects in the mechanical sector of the casting equipment, including shell casting, precision core molding, silica sol investment precision casting process and equipment.
