There are many reasons for this ‘ scrap cycle ’: rejects during the production of semi-finished products , ( planned ) offcuts in the processes or rejects from the finishing processes .
Sustainability benefits
Leaving the production of semi-finished products aside for a moment , there are two main challenges for production processes . On the one hand , it is important to reduce planned waste and therefore the amount of material used . Secondly , the process must be controlled in such a way that rejects are avoided or at least recognised at an early stage before entire batches are declared as rejects . Roll forming is a manufacturing process that meets both these challenges .
In roll forming , an initially flat metal strip is gradually formed between forming rollers into an open or closed finished profile . Forming
