Covered sand investment casting and sand casting production process, is a large batch, the weight of 0.5KG-15KG between cast iron, cast steel, alloy steel, stainless steel products reasonable choice. Tolerance CT9. Roughness between Ra12.5 and Ra25.
The covered sand investment casting process involves creating a mold by coating a ceramic shell with a fine-grained sand mixture. The shell is then heated, and the sand mixture hardens to create a dense mold. Molten metal is poured into this mold, and after solidification, the casting is removed by breaking the outer shell.
On the other hand, the sand casting process utilizes a mixture of sand, clay, water, and other additives to create molds. The mold is prepared by packing the mixture around a pattern, which is removed once the mold has hardened. Molten metal is then poured into this mold, and the casting is removed after it has solidified.
Both of these processes offer advantages in terms of manufacturing precision, surface finish, and simplicity. Moreover, they are ideal for producing large batch quantities of cast iron, cast steel, alloy steel, and stainless steel products. They enable manufacturers to reduce costs, ensure consistent quality, and meet strict product specifications.
It is widely used in automobile, construction machinery, agricultural machinery, food machinery, electric power communication, transportation rail and other industries. Moderate price, high production efficiency, environmental protection and energy saving.
