Mould Flow Analysis
What
is a Hot Runner System?
It
is a system to mould plastic components
without the use of runners and sprue
bushes. In essence, the plastic material
flows in a hot melt condition directly
from the machine nozzle into the mould
What
does it do?
Hot
Runner Systems are broadly designed
to achieve the following objectives:
Eliminate the use of runners and
sprue which in the case of engineering
plastics are generally discarded
and result in scrap.
Improvement in the cycle time
of the mould, by reducing the time
needed to fill the mould.
Moulded products are generally
stress free and do not have weakness
in the weld lines.
The temperature of the moulding
cycle can be controlled more effectively.
Reduction in power consumption
as the booster pump needs less time
to fill the mould.
Moulded product weight can be
controlled to very high tolerances.
This is particularly important in
the case of critical components
like connectors or automotive press
fit parts.
Types
of Hot Runners
Internally insulated type i.e.
where the raw material flows around
the heaters and into the nozzles
which again have heaters in the
middle.
Single Cavity hot sprue bush,
where the sprue bush acts as a direct
injection into the part.
Manifold Type where the runner
channels are externally heated i.e.
along side and generally the manifold
is machined out of high quality
steel and the heater and other channels
are gun drilled.
Valve Gate Type, where the gate
of the nozzle is activated by a
valve working on the machines hydraulic
systems.
Benefits
Reduction in raw material consumption
due to absence of cold sprues and
hot runners
Improvement of cycle time
Savings in power
Consistent and high quality moulded
product to close tolerances
