Core Processes

Basically the manufacture of doors consists of the aluminium processing
and foaming process: the so-called PU foaming process.

On the other hand, the core processes within the aluminium processing
are the bending of profiles on state-of-the-art CNC bending machines
and the joining with the aid of a robotics-supported bonding technology.

HARTAL also has its own electroplating plant and two vacuum machines
for the production of the inner elements of the doors.
