Mestek Machinery flanging machinery — engineered and manufactured through our Lockformer brand — was designed to meet the specialized needs of today’s HVAC duct manufacturing shops. Built to maximize productivity, our flangers process high-gauge material to create precise flanges from single-wall, double-wall, round and oval ring connectors, and more. Lockformer Auto-Guide Power Flanging Attachment — designed to work with our Lockformer Pittsburgh Lock Roll Formers — automatically follows any edge (straight, inner, or outer radii) while forming a 7/32 (outside) flange height with no change over between Pittsburgh Lock and flanging operations. The Lockformer Button Punch Snap Lock Flanger allows you to roll punched, right-angle, single-direction flanged curves that fit perfectly in the receiver formed on Lockformer Button Punch Snap Lock Roll Formers. The Lockformer Easy Edger Manual Flanging Machine turns perfect flanges on elbows or other curved fittings as fast as you can notch them and the Lockformer Model 16 Flanging Machine automatically follows any edge – curved or straight — and uses the convenient table slot to automatically turn up a “starting flange”.
