Preparation of Feed Metal : The billet or ingot is the feed metal used as a raw material in the extrusion process. However, the feed metal must adhere to the designers' specifications. It usually has a circular or square profile but can also have other shapes. The feed metal is produced using hot rolling or continuous casting techniques.

Preparation for Extrusion : The standard raw material is then placed in extrusion equipment, such as a press, and heated to the temperature recommended for the hot extrusion method. Because cold extrusion occurs at room temperature, no preheating is required.

Metal Extrusion : The extrusion process is now carried out by applying a compressive force to the material, which pushes it toward the die. There is a small opening in the die. The pressure is released when this process is finished, and the product proceeds to the next step.

Heat Treatment and Post-Processing : Heat treatment is now applied to enhance the product's qualities and prepare it for its intended use. Different metals require different heat treatment procedures. In the case of aluminium, for instance, it first cools the extruded portion before stretching and cutting it to the required lengths. The pieces are then heated to 350 degrees Fahrenheit and left to cool for four hours when they undergo an ageing process to become hardened.
