General
FasTie Quick-Connect Ejector System “ties-in” the
mold ejector plate to the press ejection system. A
pneumatically-operated piston inside the coupler
releases the pull stud from the press ejection system
to reduce set-up and change-out times.
Fixed-length FasTie Knockout Bars may be used
with the couplers and pull studs. The FasTie air
manifold option distributes shop air to each coupler.
The aluminum manifold supplies air to up to four
couplers. Pneumatic fittings and tubing are included.
Maintenance
Use Ultra High Temperature Synthetic Anti-Seize grease regularly on
the couplers for smooth operation. Visually inspect coupler each
month or each tool change for the presence of grease. Generously
apply grease to pull stud end, connect the coupler to the pull stud,
then release and repeat.
Before Installation
Before clamping a mold to the injection molding machine, the
machine ejector plate must be completely retracted to the “home”
position.
Alignment
Per figure 2, maximum center line misalignment per coupler
outside diameter is as follows.
1" HS
±3.5mm (±0.138")
1-3/8"
±5mm
(±0.197")
2"
±6mm
(±0.236")
3"
±5mm
(±0.197")
Multiple Knockout Bar Lengths
When using two or more knockout bars in an installation, knockout
bars must be the same length within .05mm (.002") to assure even
coupler operation.

Caution: Couplers must be in the open position before
connecting with pull studs. See figure 1. Coupler
damage will result from improper set-up.
Ejector Bar Length Note:
Individual ejector bars should not exceed 24" in
length to prevent sagging and excessive
coupler/pull stud misalignment.
It may be necessary to use two ejector bars for
extra-long ejector bar applications, one for each
pull stud and coupler.
