Pressing

Pressing the aluminum profile is a deformation process used to obtain a long flat products whose length is significantly greater than the dimensions of cross sections (rods, tubes, tapes, etc.). The principle of molding is simple: due to high load (force the piston presses) Material tree snaps through the tool which gives the desired shape of the profile.

FEAL has installed four modern lines for molding aluminum profiles. The lines vary in strength presses installed. Dimensions of the cross-sectional profile and its required mechanical properties, define the material (alloy), a tool for pressing the line on which the profile will be made.
