Start-up and instructions for operation
6.2 Requirements for operation
•
The radius of the sprue bush (R) or the radius of the contact surface of a single tip respectively has to be adapted to the
radius of the machine nozzle (RM) (recommendation: R > RM + 1).
•
For a better decompression the bore in the machine nozzle has to be adapted to the bore in the sprue bush or the single
tip respectively (machine nozzle bore max. 1 mm smaller).
•
The injection unit stays attached to the mould during cycle.
•
Connect power cable, thermocouple collective cable and ground cable.
•
Check if the thermocouple and power connections are allocated correctly by heating up each zone separately
(for a short time).
•
Before start-up valve gate systems have to be checked on tightness of water, oil and compressed air connections.
•
In order to clearly identify the hot runner system attach the type plate with the order number prominently to the operator
side of the mould.
NOTE!
When operating single tips the maximum contact pressure of the injection unit must be obeyed!
