What determines the market demand for coated sand? The manufacturer of casting coated sand states:

The demand for coated sand in the casting industry is contingent upon the growth environment of downstream application sectors. For forging molding processes, coated sand is utilized, while the oil and gas industry employs resin-coated support agents, particularly for the extraction of low or ultra-low permeability oil and gas. The sustained growth of downstream industries will drive the expansion of natural gas production and promote the development of the coated sand industry, as well as the market for waste sand recycling.

Enhancing research on pollution-free phenolic resin substitutes; improving the regeneration capacity of coated sand. The regeneration process of coated sand has always been a topic of concern. Currently, the cost of coated sand recycling equipment is high, and the regeneration efficiency is not satisfactory. A hot regeneration unit with a production capacity of 5 tons per hour is priced at 12-16 million yuan, and the regeneration cost of coated sand is 65-90 yuan per ton. Such high costs are unaffordable for domestic forging companies. Therefore, developing cost-effective coated sand recovery equipment for casting has a promising market前景.
