Perforated sheet metal, how to calculate the productivity of a line

Perforated sheet metal is gaining popularity in several industries: for lighting and sun-shading applications, facades, perforated roller doors but especially for soundproofing applications, namely sheet metal walls and ceilings.

Ceiling tiles measuring 2' x 2' or 600 x 600mm are produced today in gypsum and mineral fiber, but perforated sheet metal tiles are gaining popularity in all markets. The perforation of a sheet metal, however, would be a time consuming operation with standard CNC punch presses, and the quantities are considerable. For this reasons, metal ceilings producers prefer to adopt dedicated lines, that use hard tools performing up to 1000 holes per each hit, in order to reach a sufficient productivity.

The following video shows a complete system for the metal tiles perforation and bending.






This article will show how to calculate the productivity of a perforating line, given the perforation pattern, the force available in the press and the hits per minute available >>>
