The processing
of LSR ( Liquid Silicone Rubber) with injection moulding :
Aspects of very economic LSR part production with LIM (Liquid Injection Moulding) :
- fully automatic process on slithly modified thermoplast- injection moulding machines
- very short cycle times
- highest part quality without any rework
- wasteless production with cold runner systems
- resource- and cost saving
- many possible combinations with other materials like thermo- or duroplast or many metals in one final part
The process „Liquid Injection Moulding (LIM)“
LSR-parts
are
being
made
with
heatetd
precision
moulds
on
sligthly
modified
thermoplast-
injection
moulding
machines.
After
the
2
Componets
(A+B)
Have
been
prepared
for
injection
by
the
mixing
and
dosing
machine
they
are
pumped
into
the
injection
unit
of
the
IM
machine.
The
material
than
gets
injected
into
the
mould
trough
special
cold
runner
systems
(-decks)
into
the
heatetd
mould.
Here
the
LSR
paste
cures
in
just
a
few
seconds
at
temperatures
of
140°C-220°C
to
a
rubber
like
consitency.
The
demoulding
of
the
parts
is
done
by
mechanical
ejectors, pressured air and / or linear handling systems or brushes.
