Shell moulding is a metal casting process that uses a mixture of resin-coated sand, known as shell sand, to create moulds. The process involves pre-heating the pattern, placing it in a metal flask, and then filling the flask with the shell sand mixture. The heated pattern quickly cures the sand, forming a rigid shell around it. After the pattern is removed, the shell mould is ready to be filled with molten metal, resulting in more precise and dimensionally accurate products compared to sand casting products.<\/p>\n<\/div>
