More flexibility thanks to new
robot system
The production of three-component screwdrivers at WITTE Werkzeuge will now run
simultaneously on two automated robot systems. This ensures a significant increase in flexibility.
For example, it enables two different designs to be produced at the same time.
This has been achieved by installing and
optimising a new robot system. As early
as January, the system itself was set
up and linked together with existing
machines. The implementation of the
automation process then commenced
in cooperation with the supplier. It was
further optimised in recent months and
adapted to the manufacture of Maxx-
Pro screwdrivers. As a result, production
now runs smoothly. The new system
comprises three interlinked injection
moulding machines; the handling is
carried out by a Kuka robot. The Maxx-
Pro screwdrivers are created in three
production steps. Initially, the inserted
blades are picked up by the robot and
placed into the first machine, where
they are injection-moulded with the first
plastic component. The semi-finished
parts are then removed and cooled. The
second and third plastic components
are injected one after the other without
a cooling phase. By expanding its production
in this way, WITTE Werkzeuge
is able to respond to the increased demand
for high-quality screwdrivers.
