Mold-Masters Hot Runner - System and Plate Screw Torques

15.14.6 System and Plate Screw Torques
Torque sequence and step torquing: We recommend that system screws be
torqued in a standard bolt pattern and that the specied torque be achieved in
3 steps (1/3, 2/3 and full torque).
CAUTION
Bridge manifold mounting screws should be torqued 1/3 higher than
specied on General Assembly drawings.
CAUTION
CAUTION
For systems with MasterSHIELD, tighten the system screws from the center
outward to exert an even load across all screws during assembly. Tighten
the screws to the specied torque in a minimum of two steps.
CAUTION
Quality and length of screws must be as specied on Mold-Masters General
Assembly drawings.
