Automation & Robotics
As challenges in efficiency, productivity, quality, staffing, and safety continue to grow, the need for industrial woodworking machinery and woodworking automation solutions has become critical. We’ll transform your concept into reality with our internal design-build capabilities and advanced, technology-driven mechanical and electrical engineering expertise. This includes integrating robotic functionality for machine tending, sorting, stacking, and destacking, performing these tasks safely and efficiently, particularly when skilled labor is hard to find. Our woodworking robotics integration ensures that every part of your production line operates smoothly, improving throughput and reducing operational costs.

Vertically integrated manufacturing in the USA means we control every step of the process to deliver the performance and longevity that the industry has grown to expect from us.
Listening to your specific needs, we will adapt a standard machine or develop a fully custom solution, including automation and robotics, and manufacture it in-house.
Our state-of-the-art production space has room to build, test and prove large-scale design solutions. Design-build teams work together to make your custom concept a reality.
We will always support your machine. From training programs to replacement parts, schematics to software support, we’ve got you covered, remotely or onsite.
