Tooling stops are required to insure a die gap that cannot close on a continuous molding machine. An in-
advertent closure of the die gap could cause very high pressures in the extruder barrel and extrusion head
and result in their damage and/or failure.
The above comments must be considered for the proper installation of either a Moog supplied die gap
tooling actuator or a customer supplied actuator.
The extruder barrel and/or screw can be severely damaged if the die gap closes when the
extruder is running. A mechanical motion stop must be installed which will not allow the die
gap to close.

MOOG DIE GAP TOOLING ACTUATORS
The Die Gap Tooling Actuator is designed specifically to control the die gap motion in blow molding ex-
trusion heads. Their design specification includes: Low friction, Long life piston and rod seals. Graphite flake
cast iron rod bearings to absorb potential side loads and high temperatures. Provision for blow air through
the piston rod, and pre adjusted position feedback transducer.
The mounting provisions for a die gap tooling actuator must include: a strong mounting structure, provisions
for axial and parallel alignment of the tooling actuation rod (mandrel) with the die gap actuators rod, pro-
visions to allow the actuator stroke center and the tooling’s effective stroke center to coincide, tooling
motion stops to protect the tooling and/or extruder. “
