The
hot runner is performing the work of keeping the plastic granules in their
liquid state as they have a controller for temperature and can keep the
internal temperature to the same place for the free flowing of the material.
The hot runner nozzle in the runner
is of two types and one is heated internally and the other type is the external
heating of the nozzle with the help of coils. These coils run externally and
are heated.
When
these coils are heated the touch of the coil does not remain constant. There
are some air bags created in the middle and so the coil does not heat the
runner in a uniform manner. The hot
runner mould heaters are used for keeping the temperature inside in
control and in an uniform state. The control on heat is the main condition for
injection molds and these are for the creating heat profiles that can help in
reduce of materials that goes waste. Now the material remains liquid and the
nozzles are better tipped and the molds can also take more heated materials.
These
eliminates the chance of overheating in the runner or the leaking of the liquid
or the maintenance downtime for the nozzle when you have these hot runners for
using in the preparation of the molded goods. The hot runner is therefore preferred over the cold runner mode and
still there is many a factory where both the runners are used for different
types of situations. The incorporation of internally heated runners are
preferred in most cases but the factories continue maintaining both the
processes.
