Shut
off nozzles - 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.

How
to choose the correct Shut off nozzle
Selection of the right Performer nozzle is based on your
injection pressure, machine size, flow rate, sled travel
and material. Answers to these questions will help determine
nozzle selection.
|
| 1.
What is your plastic melt injection pressure? (Not the hydraulic
system
pressure) |
| |
If under 18,000 psi, any of the Performer series shown
can be used. If over 18,000 psi, but less than 30,000 psi, use the
2900 Series. |
| 2.
What type of material is being processed? |
| |
General purpose materials with no fillers can be processed through
any Performer. For materials which are corrosive, have additives
or are shear sensitive - call. |
| 3.
Measure to determine which series nozzle will fit your platen. |
| |
Note the overall “A” dimension
on the drawings. (The minimum OAL can be reduced further by building
a combination one-piece
machine adaptor and end cap). |
