The ABB IRB 4400 robot is one of the
most sought after on the used market. There are two main reasons for this,
firstly they are not used in large numbers in the automotive industry and
secondly they are ideal for many medium capacity/reach applications. The 4400
has a small footprint, excellent speed and flexibility with a great combination
of reach and capacity. It’s comparatively light weight means that it is
regularly installed on a 7th axis track giving the possibility to
vastly increase the robot’s working range.
The IRB 4400 is available in 4 different
configurations, the standard and 60kg versions being the most common.

The 4400 can be used in many applications including pick and place, machine
tending, grinding, welding, de-burring, trimming, and sealing. They are
especially popular in the injection molding industry where they can be used to
load and unload and perform IML (in mould labeling). The 4400 has excellent
accuracy and therefore is commonly used for laser cutting. There are some very
highly modified 4400 robots where the whole top arm is replaced with a CO2
laser but it is more usual to have a fixed laser and use the robot to move the
part.
