The tool is used in the manufacturing of aluminium profiles. A tool, also called a die, is the instrument used for pressing heated, aluminium alloy blocks/billets to mould the final aluminium profiles. The process is called extrusion, and depending on whether a solid profile or an aluminium profile is made, different tools are to be used.
Different tools – different aluminium profiles
As this is the tool through which the aluminium is pushed to produce the final profile, it determines the appearance of the profile, which is why different tools are used for the production of different profiles.
The choice of tool depends on whether solid profiles or hollow sections are to be manufactured. As seen in the illustration, one tool is used to produce solid profiles, whereas the production of hollow sections requires a two-part tool. These two parts consist of, respectively, a tool/die and a core forming the cavity of the profile.
