This is a rectangle pipe after bending. Bending rectangle pipe is more difficult than bending round pipe. The deformation rate is also high. We make high precision mandrel and tooling to avoid deformation.

We BLMA's CNC tube punching machine can punch different size holes.  We can customized tooling according to client's drawing.  Not only small holes, big holes, square holes, round holes or other special holes.  And not only cooper tube, mild steel tube, stainless steel tube, channel U steel, flat plate, all can be punched by our pipe bending machine.

These are pipes with small punching holes.  These workpiece are mainly used for market shelf, warehouse shelf, etc.  Using our CNC punching machine can punch different size holes automaticly.
