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
- Four 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

Specific Application Benefits
|
Conventional Molding:
- Control nozzle temperatures without freeze-up or drool
- Speed recovery rate and reduce cycle times
- Inject into parting line to eliminate sprue and cut material usage
- Permits structural foam molding
Gating directly into Part:
- Cut material use and lower tooling costs by eliminating the sprue and runner
- Cut start-up time
- Faster color changes than hot manifold method
Gating through Core: Eliminate gate blemishes on large parts where cosmetics are important.
Three Plate Mold Design:
- Eliminate sprue by injecting directly into runner system
- Eliminate stringing and poor ejection of runner system
- Mold runs automatically
Vertical Injection Molding: Cut material use by injecting through the parting line. |
Why the patented EMI Performer 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
