The extrusion process starts with the creation of die by experts. Die is the heart of aluminium extrusion; therefore it has effects on the important processes like surface quality of profiles, dimensional tolerances of profiles, extrusion scrap rates and production speed. Tuna Aluminium produces approximately 1000 unit of die in a year in our CNC-centered molding room which is equipped with CAD/CAM-assisted technical draw unit and modern lathe-levelling machines.
