Aluminium extrusions are used in commercial and residential construction sector for window frames, doors and curtain walls, in prefabricated house and building structures and in numerous other applications.
In direct extrusion, a stem with a pressure bearing in the front pushes the billet in a stationary container, through a tool with the desired shapes, the die. The relative movement occurs between the billet and the container. Orange Evp Italia has developed several back-loading and front-loading presses for aluminium, copper or brass.
In indirect extrusion, the die sits in front of a hollow shank pushed against the billet from the forward movement of the container closed on the back. There is, therefore, no relative movement between the billet and the container. Orange Evp Italia has developed a different solution for the fixed or mobile mould pressing cycle for indirect extrusion of aluminium, copper or brass.
With regard to the extrusion process, to build seamless tubes or special profiles with the use of tough or hard alloys in direct or indirect extrusion, a good option is a press with a drill. Orange Evp Italia has developed a different solution for fixed cycle or mobile extrusion for the direct or indirect extrusion of aluminium, copper or brass.
