Casting
Casting manufacturing is a versatile process that involves pouring a molten material into a mold to create a desired shape as it solidifies. It is one of the oldest and most widely used manufacturing techniques, offering a wide range of possibilities for producing complex parts and components. In this web page, we will explore the different types of casting, their advantages and disadvantages, and the diverse industrial applications. Additionally, we'll provide a list of materials commonly used in casting manufacturing.

Sand Casting
Involves pouring molten metal into a sand mold cavity. It's versatile for various metals and sizes, and cost-effective for small batches. The downside is the rough surface finish and lower accuracy, requiring more post-processing.
Investment Casting
Uses a wax pattern covered in refractory material to create molds. It offers high precision and excellent surface finish. However, it’s more expensive and time-consuming, making it less suitable for large-scale production.
Die Casting
Involves injecting molten metal into a reusable metal mold under high pressure. Ideal for high-volume production of complex, detailed parts. The advantage is speed and repeatability. However, the initial tooling costs are high, and it’s primarily limited to non-ferrous metals.
Lost Wax Casting
Similar to investment casting, uses a wax model to create a mold. It’s excellent for intricate designs and fine details. The downside is the labor-intensive process and higher cost, limiting its use to small parts or art pieces.
Centrifugal Casting
Metal is poured into a rotating mold, using centrifugal force to distribute the metal. Suitable for cylindrical parts like pipes. Advantages include good material density and a clean surface. However, it’s limited to symmetrical shapes and requires specialized equipment.
Permanent Mold Casting
Involves pouring metal into reusable metal molds. It offers better surface finish and dimensional accuracy than sand casting. The limitation is the high tooling cost and difficulty in casting metals with high melting temperatures, making it less versatile.
Casting Materials Available
Each of these materials has its own advantages, limitations, and cost implications. The choice of material and manufacturing technique usually depends on factors like the complexity of the design, required precision, material properties, and production volume.
