From a one-man company, established in 1923, which produced precision medical
instruments, ARBURG has developed into a global company which today is one of
the international leading manufacturers of injection molding machines with small
and medium clamping forces.
Whereas the first injection molding machine was built in 1954 for in-house use,
ARBURG set off down the successful path to becoming a machine constructor with
its first series production machine in 1956. The next milestone was the
ALLROUNDER principle, developed and patented in 1961, which made it possible to
operate in various working positions on a single injection molding machine.
This principle is still available today for ALLROUNDERs from various series, in
the form of the “swivelling mold clamp” option. In this way four different
working positions can be achieved. In the first working position the injection
molding machine’s injection unit and clamping unit are both in the conventional
horizontal position. With the second working position, the injection unit is
positioned vertically and the clamping unit remains in the horizontal position.
With the third working position, the mold clamping unit of the injection
molding machine is pivoted and both the injection unit and the clamping unit are
positioned vertically. With the fourth working position, the injection unit is
horizontal whereas the clamping unit is positioned vertically.
