SR24 manifold criteria:
è
SR24 hot runner systems are designed
with preload between the thrust pads and
the mold plates in the cold condition. As
the manifold heats an additional sealing
force is created
è
Thrust pads are made of a low conductivity
material and should only be replaced with
an equivalent Synventive part
è
Excessive contact with the mold will cause
heat sinks and affect system performance.
Contact with the mold must be limited to
specified areas.
è
Support ring nozzles do not line up with
sub-runners in the manifold in the cold
condition. As the manifold heats up the
manifold sub-runner locations expand to
the correct location.
è
Minimum rail height:
