  • Green sand moulding Steps,Advantages and

    Green sand moulds are softer than dry sand moulds. This allows greater freedom in construction when the castings solidify and cool. Green sand moulds are quite strong for small depths, as the gases escape from them. Green sand moulds do not require any backing operations or equipment, but dry sand cores are to be used. Disadvantages of green sand Sand Casting Process, Defects, Design CustomPart.Net,The mold cavity is formed by packing sand around the pattern in each half of the flask. The sand can be packed by hand, but machines that use pressure or impact ensure even packing of the sand and require far less time, thus increasing the production rate. After the sand has been packed and the pattern is removed, a cavity will remain that forms the external shape of the casting.
