This
machine was produced for an automotive plastics moulding manufacturer
to automatically insert 6 threaded brass inserts and 3 steel
compression limiters into a Throttle Body Moulding.
The
threaded inserts are pressed into the moulding after heating
them to a temperature of approximately 350 deg C and are then
air cooled. The inserts are checked for correct insertion
depth, with a tolerance of flush to 0.2mm proud maximum.
The
compression limiters are pressed into the moulding at an ambient
temperature.
To
achieve a cycle time of 1 moulding every 20 seconds the machine
processes a pair of moulding every 40 seconds.
The
mouldings are manually loaded in pairs onto the locating fixtures
at the front of the machine along with 6 compression limiters.
If all parts are present and correct the cold insertion is
automatically performed at the front station and if successful
the fixture transfers the parts to the rear station for hot
insertion.
Good
assemblies are returned to the front station for the manual
fitting of a seal with positional verification and a single
character pass stamp.
