Carbon Steel and Alloy Steel: Beaded sand is suitable for alloy steel castings such as high-manganese steel and high-chromium cast iron, as well as ordinary carbon steel castings. It prevents metal penetration and sand adhesion, improving surface quality.

Cast Iron and Copper: In the production of non-ferrous metal castings such as cast iron and copper, beaded sand can reduce casting defects and improve dimensional accuracy.

For large and complex castings such as diesel engine water assemblies, machine tools, pumps and valves, and hydraulic components, beaded sand overcomes the shortcomings of traditional molding sand, such as high expansion coefficient and high binder requirements, thereby improving yield.

High-Precision Castings: Beaded sand’s spherical particles and low thermal expansion coefficient (0.13%) make it an ideal material for manufacturing high-precision castings such as aircraft engines and spacecraft components.

Ladle Drainage Sand: The high refractory properties and chemical stability of jelly sand make it suitable for ladle drainage sand, improving molten steel pouring efficiency.

Electronic equipment castings, such as heat sinks and housings, require jelly sand to meet the high precision and surface quality requirements of electronic equipment.

Corrosion-resistant and high-temperature-resistant chemical equipment: Jelly sand’s excellent chemical stability makes it suitable for manufacturing corrosion-resistant and high-temperature-resistant chemical equipment castings.
