The simplest, most versatile, and reliable way to release an undercut.
It has all the functionality of the DR, but with internal circuits in the angle shaft to cool the insert and reduce the cycle time.
Create your solution by choosing the width, stroke size, base angle, rack angle, as well as whether you prefer a standard or symmetrical option.
The main advantage is a smaller mold size, which reduces machine requirements and costs while improving plate stability.
GREAT ADVANTAGES
In the same space as the DR, you can cool the insert through the angle shaft. Thanks to their input/output connections on different sides, multiple FC components can be installed in series.
Vertical lifter system that minimizes mechanical stress on the mold.
Efficient and reliable demolding with strokes ranging from 11mm to 52mm on standard models.
Effortless installation: no need for high-precision angled housings.
Fast Fit insert attachment: choose between a magnetic or threaded system.
Total dimensional freedom of the insert.
Reduce costs by up to 40% due to an optimized design that simplifies machining and saves up to 76% on ejector plate working hours and setup compared to conventional systems.
The compact and mechanical design saves space in the mold and reduces the required size of the injection machine.
Symmetrical configuration available to suit any mold shape.
