Applications
The IR-1891 is suitable for
the installation of a range
of Raychem brand heat-
shrinkable tubing products
onto a variety of small
components, e.g. ring
terminals, FASTON
terminals and small
connectors etc. The
machine is provided with
two work stations and a
moveable heating head.
Each workstation is provid-
ed with supports for tooling
fixtures (which must be
specified and ordered
separately). These support
the workpieces and locate
the tubing products. The
operator loads the work-
pieces into the fixtures at
one of the workstations,
ensures that the tubing
product is correctly posi-
tioned and then slides the
heat head into position
before initiating the heating
cycle. The operator then
continues with loading/
unloading the other work
station whilst the heating
cycle is taking place.
The IR-1891-220V-Shuttle-
Retn is provided with
closed loop temperature
control and in addition the
heat head is ‘locked’ into
position by use of an
electromagnet during the
heating cycle.
Once the other workstation
has been loaded and the
first installation is complete,
the heat head is moved into
position over the product
and the next heating cycle
initiated. Heating times vary
typically from 3 to 30
seconds depending on the
size and type of tubing
product. Process rates up
to 1200 pieces/hour can be
achieved depending on the
heating time and the time
taken by the operator to
load unload the workpieces.
The installation tempera-
ture/power can be varied
according to product
type/size and required
cycle times.
The heating elements,
which are continuously
energized, are of the infra-
red medium wave length
type and consist of a coiled
resistance wire contained
in quartz glass tubes. The
closed loop temperature
control uses similar ele-
ments but having integral
thermocouple sensors.
Product Facts
n Automatic cycle start once
h
eater is manually
positioned over product,
which gives improved
process control
(recommended for adhesive
lined heat-shrinkable tubing
e.g. sealing applications)
n Automatic heating head
retraction at end of cycle
prevents damage to
components
n Multiple product fixture
assemblies give increased
process rates
n Cooling fan above each
fixture assembly maintains
holding fixture at an
acceptable temperature
