Sand Casting

• A mould is put into a box (drag) and then the box is filled with sand.
• The mould is removed and another box (cope) is placed on top.
• The cope has channels in it to pour the molten metal into, which fills the mould cavity.
• The mould is left to cool and then excess metal is removed.
• Sand casting is suitable for batch production.
• Large parts can be created using sand casting.
• Equipment for sand casting is cheap compared to other methods.
• The disadvantage of sand casting is that it takes a skilled person a lot of time to create one product using this method.
• The sand leaves a bad surface finish in sand casting.
• Sand casting is used to create engine blocks, gear blanks, crankshafts, and brake drums.
• Identifying sand cast products involves looking for a rough surface texture, tapered angles, and large parts without intricate detail.
