What are the different manufacturing processes for aluminum profiles?

Aluminum profiles are manufactured using several processes, primarily extrusion, but also including casting, rolling, and machining. Extrusion is the most common method, where aluminum is heated and forced through a die to create a desired shape. Casting involves pouring molten aluminum into molds to form specific profiles. Rolling is used to produce flat sheets or plates, which can then be further processed. Machining involves cutting and shaping aluminum using tools like lathes and mills. Other processes include forging, which deforms aluminum under high pressure, and powder metallurgy, where aluminum powder is compacted and sintered into a solid profile. Each process has its advantages and is chosen based on the desired profile shape, strength, and application.
