FasTie® Quick Ejector Tie-In System
FasTie Quick Ejector Tie-In System quickly “ties-in” the mold ejector plate to the press ejection system in an injection molding press, dramatically reducing mold change time.
The greatest time savings are realized in presses where space is limited and the ejector system is difficult to tie in using solid knock-out bars.
Product Overview
Installation
In a typical installation, the FasTie coupler is installed into the press ejector plate. The quick-connect locking mechanism in the coupler snaps mechanically onto the mold-mounted pull stud during mold installation.
To release the ejectors, apply shop air to the coupler. The coupler opens to release the pull stud, disconnecting the press and tooling ejector plates. The coupler remains in the open position, ready for a new mold to be set.
For multiple ejector locations, an air manifold is recommended to release all couplers simultaneously.
Four FasTie sizes are available: 1-inch, 1-3/8-inch, 2-inch, & 3-inch models suitable for most presses and knockout configurations.
Additional installation examples and accessories lists are located in the catalog available in the “Downloads” section.
SpeedBar®
SpeedBar is an adjustable-length knockout bar that can quickly compensate for variations in different molds. Used with the FasTie system, mold ejector plate tie-in and adjustment times are reduced to seconds. The adjustment sleeve is easily rotated to change the bar length up to 1 inch in increments of 006″. Once the desired length is set, the spring-loaded sleeve securely locks in your adjustment.
Fixed-length knockout bars are blank on one end for on-site finishing. Longer bars are available.

Molder Benefits
Versatility
Choose the installation method that works best for each application. Various thread sizes and press tonnages are available.
Timesaving
Change molds faster by using the quick disconnect function to tie in press and ejector plates in a "snap". Disconnect with a burst of shop air.
Ease of Installation
Modifications to the tool or press are not needed for installation.
Center Knockout Compatible
FasTie Quick Ejector Tie-In System is most useful in small presses where space is limited. Center knockout bars can be difficult to access during mold changes. Using a FasTie coupler and pull stud to connect the ejector systems eliminates the need to reach inside the press to disconnect.
Couplers and pull studs connect automatically and disconnect with a burst of shop air. Burger & Brown Engineering recommends using a momentary air switch to open the coupler.
