Sheet metal machining - Blanking
What is moulding for blanking?
Moulding for blanking is used to blank sheet metal and slabs on which to make contouring, boring, slots, and forms of any type. Blanking makes it possible to contour, even the perimeter of the part, with utmost precision. In fact, the blanking operation consists in pressing onto the sheet metal a cutting force sufficient to separate the material along the border of the cutting unit of the mould.
This type of mould is performed using a mould formed by a punch and a die which in correspondence among them blank the sheet metal to achieve a profiled element as indicated by the punch (positive) and the die (negative).
Two blanking types
There are two blanking types, simple and complex.
The first consists in the "simple" cutting process and die-cutting of the sheet metal. It must always be done skilfully to ensure evenness and to avoid possible flaws.
The second, so-called "complex", associates blanking to other mechanical processes such as bending, coining, deep drawing, thus it needs a highly detailed machine designing and equipping phase.
Mevar optimises blanking
Mevar knows the challenge isn't only to blank well, but also to optimise encumbrances, overcome constraints and take costs into consideration.
We have learned over the years that to optimise production costs for our customers, means streamline and precise blanking procedures for every different type of item, always seeking the best solution.
With the transfer blanking method (transferring) accurate finished parts are made that are characterised by the purity of the inclusions, maintaining an optimal state for the surface, verifiable by its perfect evenness.
Mevar performs blanking using moulds that we design and manufacture internally or by equipping our presses with your own moulds.
