Resin coated ceramic sand

Sintered ceramic sand is an artificial spherical casting sand developed by SHXK. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (30% reduction in binder content), and particles high strength, non-breaking and other characteristics, suitable for sand casting (molding sand, core sand), coated sand, V method casting, lost foam casting (filled sand), foundry coating (ceramic sand powder), 3D printing and other casting processes. It is green and environmentally friendly foundry sand.

Part of the ceramic sand is used in the molding sand and core sand to make the shell mold and shell core have the properties of high temperature resistance, low expansion, easy collapse, and low gas output, which can effectively prevent expansion defects in castings. For cores with particularly complex shapes, can deal with the problem that sand shooting is not easy to compact.

Full ceramic sand is used to make coated sand, and reused repeatedly after reclamation, which can effectively improve the quality and production efficiency of castings, reduce the castings scrape rate and the production cost of enterprises, the long-term use cost is lower than that of silica sand. Therefore, in recent years, almost all large-scale coated sand plants have used ceramic sand as raw sand to produce coated sand.
