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 ”A 0 ” will be made, allowing for expansion.

Installation 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.
Measurements: General toleranzes DIN ISO 2768 mK.
* Height adjustment of the whole
system according to data sheet
”Standardised hotrunner manifold”.
