Sand Casting

Sand casting, also known as foundry casting, is a long-standing and widely used casting method. Molten metal is poured into a mold using special sand, and the casting is removed after it cools and solidifies. Its advantages include low cost and the ability to produce parts of various complex shapes. However, its disadvantages include low dimensional accuracy, high surface roughness, and limited mold durability, making it unsuitable for mass production.
