Strictly separated bending tools, bending very often performed with the use of bender blankets to protect the workpieces, laser-cutting on copper studs (instead of steel laser combs as is almost always the case).
Yes, separate processing calls for a lot of extra effort (and cost). Copper studs are more expensive than iron cams but have 2 major advantages: no contamination with iron and a significant reduction in scratches during the production process. The strict separation also involves much more equipment: 2 plate bending rolls for each diameter, double bending blades for the press brakes, etc.
But if you are serious about working with stainless steel and want to provide your customers with a top-quality product, there is no option but to consistently separate the two processes.
Unfortunately we often see work from colleagues in the industry who do not take the matter this seriously. A rusty line near a bend points to the shared use of bending tools for stainless steel and iron. If bending blades are used to bend an iron sheet and the iron residue on the tools is pressed with a force of 100 to 200 tonnes onto the following stainless steel sheet, one is bound to have problems later on.
At Alinco you will find:
- separate processing workshops - iron welding and grinding are done in the iron workshop, stainless steel processing is performed in its own workshop;
- strictly separated bending tools; aside from that, we frequently bend using bender blankets to protect the material;
- laser cutting on copper studs (instead of the steel supports used by most of our colleagues);
- clear internal tracking and materials management so no mistakes can be made when changing material qualities;
- avoidance of scratches and damage throughout the entire production process; we work with the right tools;
- the greatest care for your material.
