CastExtrusion

CastExtrusion is a manufacturing process that combines elements of both casting and extrusion. In this method, molten metal is forced through a die, similar to traditional extrusion, but the die is shaped to create a hollow or complex cross-section that is continuously cast. The material solidifies as it exits the die, forming a long, continuous product.

The process typically involves melting the metal and then pumping it under pressure through a specifically designed die. The die's geometry dictates the shape of the extruded profile. As the molten metal exits the die, it is cooled, causing it to solidify into a desired shape. This continuous solidifying process allows for the production of very long lengths of material, often without the need for welding or joining multiple pieces.

CastExtrusion is particularly useful for producing components with intricate internal structures or hollow sections that would be difficult or impossible to achieve with conventional casting or extrusion alone. It can be used for a variety of metals, including aluminum alloys, magnesium alloys, and some copper alloys. The resulting products can find applications in industries such as aerospace, automotive, and construction, where lightweight and complex structural components are required. The precise control over the cooling and solidification process can also lead to improved material properties.
