Industrial Applications

1. Automated Packaging Flap Folding

Drives product-pushing and flap-folding mechanisms in high-speed packaging machinery where installation space is highly restricted.

Problem Solved

Replaces standard bulky cylinders to fit within tight chassis limits while still delivering 188N of actuating force to reliably manipulate cartons.
