The coated sand industry has entered a mature period with fewer opportunities for future development

Coated sand refers to core sand products that are coated with a solid resin film on the surface of sand grains using processes such as cold and hot methods. Coated sand mainly includes dry type and wet type, which are mainly used in the foundry industry. my country’s coated sand production technology is relatively mature, and it has achieved independent technology research and development and produced a series of products with independent intellectual property rights, such as easy-to-collapse products, high-temperature resistant products, manual wet products, etc., which can meet the needs of multiple scenarios.
Casting is an important basic process in the modern machinery industry. With the rapid development of domestic industry in recent years, domestic casting output has fluctuated and increased, reaching 52 million tons in 2020. Automobiles are currently the industry with the highest demand for castings. In recent years, driven by the development of the new energy automobile industry, my country’s automobile production and sales have resumed growth, driving the demand for castings to rise. In automobile production, engines have a high demand for coated sand, reaching about 1.1 million tons in 2020.
According to the “Coated Sand Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2021-2026” released by the Industrial Research Center, In the casting process, sand castings still occupy a relatively high proportion, reaching about 80%. Sand castings consume high amounts of coated sand, so the production of waste sand continues to grow. Since 2015, the output of waste sand in my country’s casting production has continued to rise, from 44 million tons to nearly 5,000 tons in 2020.
my country’s casting waste sand production is high, but the utilization rate is low. In the world, the waste sand recycling rate has gradually reached about 65% in the United States and 83% in Japan. However, the domestic casting waste sand recycling rate is about 25%. The recycling rate of waste casting sand in my country is low, and most of it is discharged as waste in valleys and river beds. This not only causes a waste of resources, but also produces serious environmental pollution, which is not conducive to the development of the coated sand industry. There is room for the development of the aftermarket of coated sand in the future. larger.
There are many subdivided products of coated sand, and there are many production companies, but there are few companies with a scale of more than 100,000 tons. The main companies are Yangtze Materials, Renchuang Technology, Jinying Casting, Beiyan New Materials and other companies. Although there are many coated sand manufacturers in my country, the production capacity is concentrated and the market competition pattern has changed little. And with the continuous tightening of national environmental protection policies, the market concentration of coated sand continues to increase.
From the perspective of the long-term development of the industry, the coated sand market is subject to two major threats. The first is environmental protection policies. The application of coated sand will produce toxic gases, and the domestic waste sand reprocessing market has not yet taken shape, resulting in resource waste and environmental pollution. It is not in compliance with my country’s environmental protection policy requirements; followed by market demand, coated sand is mainly used in the foundry industry. As domestic equipment gradually develops toward high-end, the accuracy, strength, and quality requirements of castings increase, and the demand for coated sand applications decreases accordingly.
Industrial analysts said that my country’s coated sand production technology is mature and there are many types of product segments, which can meet the needs of different scenarios. The industry Development has entered a mature stage. There are many companies in the domestic coated sand market, but the market concentration is high, and the concentration is showing a growing trend, and an oligopoly competition will form in the future. In addition, affected by downstream demand and environmental protection policies, the future growth rate of market demand for coated sand will be smaller, and there will be fewer opportunities for industry development.
