The MAK 4 Evolution UD is our solution for complex tasks involving industrial sheet metal working – powerful, precise, and extremely efficient.

The Evolution series combines the Schröder groups‘ many years of experience in sheet metal folding with pioneering innovations: precise linear drive, graphical programming, and an automatic tool changer.

With the MAK 4 Evolution UD you are able to work more productively thanks to the „up-and-down“ technology. All of this opens up new opportunities to your company for processing sheet metal – for faster, more flexible production and reduced costs per unit.

The MAK 4 Evolution UD enables you to turn your customer‘s increasing demands in quality, flexibility, and speed into competitive advantages for your company. No matter whether complex sheet metal forming needs to be particularly precise, short-notice individual orders need to be managed reliably, or pieces of sheet metal need to be processed quickly and efficiently for standard products, the MAK 4 Evolution UD makes it all possible.

Up-and-down technology reduces processing times

Minimize handling costs at the machine and trust Schröder‘s proven “up-and-down” technology. More processing steps in shorter times.

The POS 3000 3D-graphic control Only the right software turns hardware into a flexible, easy to operate solution. With the POS 3000 3D graphics control, sheet metal working specialist Schröder has developed one of the most powerful controls on the market, and because both the hard and software come from a single provider, the MAK 4 Evolution UD and POS 3000 3D graphical control are a perfect match.

From the drawing straight into production The POS 3000 software control allows you to import DXF, BPX and GEO-files. Hence the most important product- and folding parameters can be imported automatically and without any intervention of the operator. Using this function, all shapes of a sheet can get displayed and the operator can choose between additional gauge options. This means substantial time savings and has the additional advantage that the operator does not have to program the workpiece that has to be bend.

Special feature: POS 3000 allows graphical programming. Machine, tools and workpiece – everything is displayed clearly. As we know: Operating staff and planning engineers are experienced in products and not for IT programming. That‘s why your employees simulate the bending process visually beforehand, check the result in the 3D bending simulator and ensure that the workpiece will be processed accurately from the fi rst bend. Once a bending program has been generated it can be displayed quickly, checked visually, and adjusted according to material requirements.
