Liding Hidden Door Upright Forming Machine

We’ve been making cold roll forming equipment for 30 years, and we know exactly what frustrates interior finishers and furniture makers the most about hidden door uprights. Hand-bent uprights are never perfectly straight, they leave unsightly gaps between doors and frames, and they take hours to make even a single set. Cheap imported machines produce inconsistent profiles that warp easily, and they break down after just a few months of use. This Liding hidden door upright forming machine fixes all these issues permanently. It turns raw steel coils into perfectly straight, dimensionally accurate hidden door uprights and metal furring channels in one continuous process. No more manual bending, no more sanding gaps, no more customer complaints about uneven doors. It’s the compact, reliable workhorse your workshop needs to speed up production and improve quality.
