The dished heads are very versatile, but each industrial sector requires special processing.
When internal enamelling is required, for example in the sanitary hot water industry, the edges must be slightly rounded to prevent the enamel from chipping and damaging.
But how is this type of edge obtained? This specific process is called edge radiusing.
The first phase consists in trimming the convex bottom, eliminating the excess sheet metal, until the desired height is obtained. Only at this point is it possible to round off the sharp edge of the bottoms.
This operation allows to eliminate any burr formed both inside and outside the edge, simultaneously rounding the edges on both sides.
At the end, when the final thickness has been reached, we proceed with the creation of the actual edging.
