CNC punching hinges
CNC punch presses have been used to produce sheet metal blanks for many decades now. Punching in holes at speed is their strength. Circles, squares, rectangles as well as special shapes are meat and drink for CNC punch presses. They are also a great tool when it comes to producing forms in the third dimension. Whether it’s down forming dimples, extrusions with tapped threads or stamping letters, number of symbols they are at home. Up forming ventilation louvres, small folds, earth tags and hinges.
Taking a walk around our workshop I saw these sheet metal hinges being formed on our Trumpf 200 CNC punch press. They show perfectly the flexible nature of manufacturing sheet metal components with a CNC punch press.

Building in the male and female forms of the hinge to either side of a bracket is a neat design idea. It not only looks cleaner than welding / spot-welding but it’s a lot cheaper to produce.
Two tools are used to form the loop up and then form over I nth sheet. All the material around the hinge form is CNC punched out first and then in this case the complete set of parts were dropped down the machine’s part chute. This speeded up the removal of finished parts and removed the need to tag into the sheet.

With both our CNC punch presses and laser machine supported by Radan sheet metal CAD/CAM software we are able to pick the right method of manufacturing to suit your bespoke design.
