Performer Shut-off
Nozzles -
save time, material and money. |
|
Positive
open, positive close, provides
faster cycles and more safety.
EMI Performer Shut-Off
Nozzles help optimize molding machine productivity by allowing
the screw to retract while the mold is opening and closing.
You’ll shave cycle times to a minimum and increase fill
rates for high speed or large part molding. Positive, air operated
pin closing allows faster screw recovery and stops drool in
its tracks.

| Why
Choose the Performer Nozzle? |
|
- Designed
to be virtually maintenance-free,
- Available
to fit any machine.
- Interchangeable
nozzle tips adapt to a variety of plastic materials and
molds.
- Alternate
shut-off pins are available in 17-4PH stainless steel and
CPM-9V® tool steel for processing corrosive and abrasive
materials.
- Powered
by two air cylinders - much safer than hydraulic operated
nozzles which can leak and flash fire. EMI Performer
nozzles are the only nozzles in the industry with this
feature.
- Mica
insulation protects air cylinders from heat.
- 4
large paths through the body allow material to flow through
with minimal shear. For very shear sensitive materials
or fast injection rate molding, we oversize the flow
through paths to further reduce shear.
|
Why
the patented, EMI design Performer Shut Off Nozzle,
out-lasts and out-performs every other shut off nozzle |
- With spring-operated
valves, you cannot positively control shut-off because spring-operated
valves are dependant on injection pressure. With heat variations,
springs fail prematurely. The springs themselves actually restrict
resin flow and make color changes more difficult.
- Single
air valve designs wear unevenly at the cross-arm and pin, which
loosens the shut-off seal making them prone to leaking, drooling,
and expensive maintenance.
- Hydraulic-operated
valves have seals which may leak oil onto heater bands and
other heated surfaces which may flash fire.
