Aluminum trim is manufactured from through the extrusion process. In this process, metal shapes called billets are forced through a die by means of a ram. The die is a hollow profile that is used to form the thin, narrow, long trim shape of the metal as it is squeezed through.
This process can be performed at room temperature, slightly above room temperature or at high temperatures: these three different methods are referred to as cold extrusion, warm extrusion and hot extrusion. When it comes to aluminum trim, hot extrusion is the most commonly utilized extrusion method. Because weather resistance is important, the trim is often post-forming heat treated to increase strength and corrosion resistance properties.
