Two patent-pending production platforms were designed, built, and refined in Keene, New Hampshire. Purpose-built for industries that demand precision, small footprints, and equipment built to last.
Most of what we build is one-of-a-kind. But sometimes a custom solution is so effective, so compact, and so different from what the market offers, it becomes a product of its own. ProCut AF and ProFill SF are our two patented platforms. Each one started as a custom build, refined over years of real production, and engineered into something no one else makes.
Alcohol-free tube cutting with automated precision.
The first machine to automatically measure and cut tacky medical tubing without alcohol, water, or compressed air. Plug it into a standard outlet and start cutting. Our patent-pending bushings enable frictionless feeding and consistent cuts. Each blade delivers more than 250,000 accurate, particulate-free cuts. Designed for medical tubing production in cleanroom environments.
Spec callouts:
Loading, filling, reflowing, capping, and labeling in one self-contained unit.
Our patented lip balm filler competes for the highest production per square foot on the market. An entire production line in a footprint of 11 feet 8 inches by 5 feet 5 inches. Portable on wheels. Runs on a single 208-240 VAC outlet. Engineered to bring outsourced filling in-house, or to scale existing production without expanding your floor plan.
Spec callouts:
A patent means the engineering inside these machines cannot be replicated by another manufacturer. It is proof that the solutions we developed are genuinely new, and it is a commitment that the platforms you invest in remain distinctly ours. For your operation, that translates into capability you cannot source anywhere else, and a partnership with the team that invented it.
Every Lehnen product starts the same way: a customer asks us to solve something that off-the-shelf equipment cannot. We design, build, and deploy a custom solution. Over time, we refine it based on how it actually performs in real production environments. When a custom build is not proprietary to the original customer and proves itself across years of operation, we patent it and offer it as a platform to the broader industry. ProCut AF and ProFill SF are both part of that story. Custom work, field-tested and refined into products.
Custom assembly lines and filling systems engineered around your specific process.
Small-footprint automation for controlled environments, where both our patented platforms perform.
SCADA, HMI, and data systems are engineered into every Lehnen product from the ground up.
