Metal casting is a process in which molten metal is poured into a mold, allowed to cool and solidify, and then removed as a finished product. This process is widely used across various industries, including automotive, aerospace, and construction. In this article, Newinds will explore different types of metal casting and their applications.
What is Metal Casting?
Metal casting is a manufacturing process in which cast metal parts are created by pouring molten metal into a mold cavity. These molds are designed with specific shapes and dimensions according to product drawings to meet project requirements. When the metal cools and solidifies, it takes the shape of the mold, forming a finished product. This process is well-suited for producing complex-shaped components and is commonly used in large-scale production.

Different Types of Metal Casting
There are various metal casting methods available on the market today, each with its own advantages and applications. Below are some of the most common types:
1. Sand Casting
Sand casting is one of the oldest and most widely used metal casting methods. In this process, molten metal is poured into a sand mold. Since sand molds can withstand high temperatures, this method is suitable for casting large and complex metal parts.

2. Die Casting
Die casting is a high-pressure casting process where molten metal is forced into a mold under high pressure. This method is commonly used to produce high-precision, high-volume parts with smooth surfaces. It is also used for casting iron and other non-ferrous metals.

3. Investment Casting
Investment casting, also known as lost wax casting, involves creating a wax model, assembling it into a wax tree, and then dipping it in multiple ceramic layers to form a mold shell. The wax is then removed by heating, the ceramic mold is fired, and molten metal is poured in. Once the metal solidifies, the mold is broken to retrieve the product, followed by cutting, finishing, and quality inspection to ensure precision and smooth surface finish.

4. Centrifugal Casting
Centrifugal casting uses a rotating mold to distribute molten metal evenly along the mold walls. This method is highly effective for producing cylindrical components such as pipes and bearings. It ensures high strength and minimizes defects.

5. Gravity Die Casting
Gravity die casting is a molding technique in which molten metal is poured into a preheated metal mold under the influence of gravity, without external pressure. This process is widely used in the automotive industry to manufacture cast steel components with high mechanical properties.
