Thermoject® Nozzles Premium
Big Shot-series
2076 HK/OH - open gate DO/DOL + ring gate DR/DRL
Low heater price and quick
availability
With this generously dimensioned
melt channel geometry and the innovative heating technology the processing of nearly all plastic types and a
large application spectrum from 400g
up to 6,000g is possible (relating to
low viscosity materials).
By sheathing the nozzle flange with
a heat conduction, the number of
heaters could be reduced. The using
of similar heaters in standard lengths
lowers the price and increases the
availability.

Low stress injection
molding reduces the reject
loss


For nearly all plastic types and
shot weights up to 6,000 g
2
The exact heater positioning and the
adjustment of the heat capacity to
the stepless nozzle length ensure a
homogeneous temperature profile.

•The number of control circuits per nozzle depends on the nozzle length.
Marking consecutively by starting at the gate (max. 3). Use 4 control circuits
per nozzle for heat sensitive plastics, see PSG's specification.
•The number of control circuits per nozzle can be determined from the
“Heating” section on the above table.
•By specifying the mold measurement A, with details of the molding material, the nozzle dimension A0 will be made, allowing for expansion.

Minimum nozzle length A1 depending on manifold's inside dimensions (x/y).
While heating up the screwed-in nozzle an extra bending moment is built up on the nozzle axis because of the
manifold's linear expansion.
The bending moment depends on the inside dimension of the nozzle (direct flow way from the center per example
sprue bush to inside dimension).
Furthermore the bending moment depends on the ∆T (melt temperature - tool temperature)
Assumed ∆T = 250°C.

Notice: If A1= 130≤150 (please contact PSG)

K = Contact height
Install and construction note:
•Cooling must be provided close to the gate, with circulating water. On the moving side
of the mold a fountain type cooling, opposite to the gate should be used.
•The front face of the nozzle head must be completely in the melt. Where the gate is on
a sub runner, a thin disc should be molded immediately in front of the nozzle head.
•Reduce the contact surface to the tool in the area of the nozzle head if you use elongated nozzle heads DOL/DRL.
Please see diagram "Contact height for elongated nozzle heads DOL/DRL"
Connecting Leads:
Connecting leads of the nozzles are heat resistant max. up to 200°C
and may not have direct contact to the beam of the manifold.
