EVO DuoBend


The new motorized folding machine EVO DuoBend owes its name „DuoBend“ to its two independently operated folding beams. With the EVO DuoBend, the Schröder Group is once again increasing its flexibility in the area of sheet metal folding many times over: Products for container construction, vehicle construction or conventional folding applications, such as heavy sheets with counterbends, can be manufactured efficiently.

POS 3000 3D graphic control:

Interactive sheet design
POS 3000 3D graphical controls is one of the most powerful controls on the market, and because both the hard- and software come from a single provider, the SPB Evolution UD and POS 3000 3D graphical controls are a perfect match.

Working with POS 3000 is extremely comfortable:

Clearly laid-out product selection including a search function and navigation in submenus enables the operator to select work steps and connect them in the production plan menu to create sequences. Individual product profiles can be designed very quickly via the intuitive finger-activated drawing feature. The exact dimensions may be entered and changed in the dimensioning menu. In order to check and coordinate together with the customer, the drawing may be output on paper using a printer.

Using the program that is created, the software generates the optimal sequence of bends, including automatic collision and threshold value monitoring. The folding angle and cut are corrected automatically using interpolation from the database.

Unfold software – Schröder Unfold

Uncomplicated and simple

In order to coordinate hardware and software perfectly, Hans Schröder Maschinenbau developed an unfold software to calculate the blank size and program with effortless preciscion.
