What is Sand Casting?

Sand casting is a traditional and widely-used manufacturing process for creating metal parts by pouring molten metal into a sand mold. The mold is made by compacting sand around a pattern of the desired shape, which is then removed to leave a cavity. After the metal solidifies, the mold is broken away to reveal the cast part. Sand casting is versatile, cost-effective, and suitable for producing complex shapes and large parts in various metals, including aluminum, iron, and steel.

Our Sand Casting Process

Green sand casting is a widely-used metal casting process that employs a mixture of sand, clay, and water to create molds. The term "green" refers to the moisture content in the mold material. This method is cost-effective and versatile, making it suitable for producing a wide range of metal parts, from small to large sizes. Green sand casting is popular due to its simplicity, ability to produce complex shapes, and adaptability to various metals.

Shell molding is a precision casting technique that uses a thin shell of sand bonded with a thermosetting resin to create molds. The process involves coating a heated pattern with the sand-resin mixture, which hardens to form a shell. This method offers better dimensional accuracy and a smoother surface finish compared to traditional sand casting. Shell molding is ideal for producing complex and high-precision metal parts with intricate details.
