Aluminum extrusion is a manufacturing process that shapes aluminum by forcing it through a specially designed die. This process allows for the creation of complex cross-sectional shapes, which can be used in various applications, from construction to automotive parts. The resulting products are lightweight, durable, and resistant to corrosion. The extrusion process begins with heating aluminum billets until they become malleable. Once softened, the aluminum is pushed through the die using a hydraulic press. After exiting the die, the extruded aluminum is cooled and cut to the desired length, making it ready for further processing or assembly into final products.
