18. Apply lockout / tagout. Refer to the controller and machine manufacturer’s 

documentation for procedures.

Latch the Cavity Plate to the Core Half - continued

15.13 Latch the Cavity Plate to the Manifold Plate 

(Hot Half)

WARNING

Make sure the machine has been locked out and tagged out in accordance 

to the machine’s documented procedures. Failure to do so could lead to 

serious injury or death.

CAUTION

 The nozzles must be within 55°C (130°F) of mold temperature to prevent 

damage to Hot Runner and mold components. For cylindrical valve gated 

systems, valve pins should be in the open position prior to removal of the 

cavity plate to prevent damage.

CAUTION

1.  Check the machine is locked out / tagged out.
2.  Lubricate the guide pins on the Hot Half.
3.  Remove lockout / tagout.
4.  Check the machine is in Mold Set mode.
5.  Slowly close the mold.
6.  Check the machine has been locked out / tagged out. Refer to the 

controller and machine manufacturer’s documentation for procedures.

7.  Remove the latches on both sides of the mold.
8.  Latch the cavity plate to manifold plate or manifold backing plate.
9.  Remove lockout / tagout.
