Sheet metal working and cold metal forming<\/strong> – sector to which we have chosen to dedicate our business and which brings with it many advantages, as we have explained in this article<\/span><\/a> – contain a wide range of processes designed to create the final product through permanent<\/strong> deformations<\/strong>. Among these, a crucial phase is that of shaping<\/strong>, which consists of two specific operations: blanking and punching.<\/strong><\/p>\n

In both processes a force is impressed on the sheet to give a specific shape to the metal on which you are working. Furthermore, blanking and punching<\/strong> use molds and punches<\/strong> to complete their deformation. Despite having these points in common, blanking and punching<\/strong> differ substantially in the way they are carried out and in the result they allow to obtain. Let’s see specifically their characteristics.<\/p>\n

Blanking to shape the metal\u2019s edge<\/strong><\/h3>\n

During the blanking<\/strong> phase, action is taken directly on the perimeter of the part to be machined, shaping it. Specific presses are used to obtain a perfect edge shaping<\/strong>, depending on the shape and size of the sheet to be processed. In the blanking phase<\/strong>, in which the punch and die intervene, the punch removes part of the material to obtain the desired result. The part of sheet metal removed, technically defined as scrap<\/strong>, constitutes the processing waste and cannot be recovered for other processes.<\/p>\n

Punching to obtain holes and notches<\/strong><\/h3>\n

Unlike blanking, the punching process<\/strong> allows you to make holes and notches<\/strong> on the surface of the sheet always using the action of the punch. In this case it is possible to assign the punching operation to both a press<\/strong> and an automatic punching machine<\/strong>. If, in the blanking, the material separated from the original piece constitutes the product, in the punching the exact opposite occurs: it constitutes the waste.<\/p>\n
