FasTie®
Quick-Connect Ejector Tie-In System
Couplers on Press Ejector Plate
for multiple molds in the same machine with different ejector
patterns and different ejector strokes
The following installation instructions are for reference only.
Installation may vary depending on the application and
customer preferences.
1. Install the coupler into the press ejector plate populating
for the required molding machine patterns (i.e. vertical,
horizonal and/or center knockout positions). Use thread-
locking compound to prevent movement during use.
2. Install pneumatic fitting to the coupler per figure 3.
3. If using the manifold accessory, mount the manifold and
tubing so they do not interfere with moving parts.
4. Connect shop air lines to the pneumatic fittings that feed
the FasTie couplers.
Couplers must be in the open
position (see figure 1) before connection to pull studs,
otherwise coupler damage will occur.
5. Install the pull stud onto the end of the knockout bar.*
6. Insert the knockout bar assembly in the moving platen.
7. Lower the mold into position and clamp the A side
(stationary side) making sure the mold is square to the
machine.
8. Position the moving platen, providing clearance between
the platen and the mold, for installation of the knockout
bar assembly into the mold ejector plate.
9. Slowly position the moving platen against the mold,
observing the coupler and pull stud. Proper center
alignment and engagement are critical at this time.
10. Clamp the B side (moving side) of the mold to the platen.
Open the mold to safe ejection position.
11. Check that air supply to the coupler is off. If press ejector
plate and FasTie system are not set at machine zero, set
Machine Ejector Back setting to match Mold Ejector Back
position. Move the press ejector plate forward to connect
the coupler and the pull stud.
12. Tighten nuts to the press ejector plate (if using) after the
FasTie components are coupled. This helps alignment of
the FasTie system.
13. Maximum allowable center-to-center misalignment of
coupler and pull stud is below: (see figure 2)

* 1” HS FasTie only: For installation using SpeedBar®
Adjustable Length Knockout bars, insert bars at step 5,
taking care to insure all bars are exactly the same length.
