Manufacturing Process
Die casting is the manufacturing process of injecting liquid molten metal under high pressure into a high precision mold. It is often used to mass produce complex three-dimensional structures with a detailed surface texture. This is done within a single manufacturing step without post treatment. The surface of the die is quickly cooled by the mold and the slowly cooling core creates a negative pressure within the cast metal, which inturn makes it more rigid and increases its structural integrity.
