Tempering<br />
Gating<br />
Reserve gating into a high gloss<br />
facing surface<br />
Sufficient cooling is recommended<br />
for the gate area, next to the <strong>nozzle</strong><br />
and on the ejector side to dissipate<br />
the heat additionally induced by<br />
shear.<br />
The cooling circuit control must be<br />
separated from the other tempering<br />
circuits.<br />
Articles with a film hinge<br />
When gating a part with a film hinge,<br />
the gating point must be located<br />
away from the surface center<br />
opposite to the film hinge. The flow<br />
front may not come to a standstill<br />
during the filling process. The film<br />
hinge must be filled last.<br />
