Production of air conditioning holder

The holder of outdoor air-conditioning units are made out of steel 11 321.21 with 2mm thickness. The production quantity is 2000 units / year. The holder is produced using CNC machine for cutting and bending on CNC press brake. The semi-finished product is a metal sheet (2 x 2000 x 1000 mm). Part of this diploma thesis is to design of the population with the punching tools, the layout of parts on the metal sheet and design of appropriate press brake punches and dies.
