POSTIONING IN THE MOLD:
Caution: Do use an Air supply of more the 6 bar (90psi) or the PPVS will be damaged.
Caution: Too much application of silicon grease will prevent the PPVS being
pushed far enough into the universal insert to the lock position due to hydraulic
effect between the O-ring seals. If it is obvious that the unit will not fully insert
remove from insert and clean off excess grease from both the O-ring and PTFE
nose section and the mould universal insert before re-insertion.
Caution: This is being placed in a possible resin pressure zone of the production
mould which under certain circumstances could result in a PPVS being force up
and out of the insert if not locked in.
Position the PPVS upright at no more then a 45degree angle from vertical and 300 –
600 mm (12” – 24”) from the injection point - TAS or IVX3.
