Powerful force just where you need it The clamping head with driving force

PowerStroke – operating principle Fast stroke and power stroke: 2 features, 2 drives Clamping head with integrated short stroke cylinder The PowerStroke mold closing device has been designed to hold and pull a clamping rod in one direction - the closing direction. It can be used in all applications that require powerful forces in a short working stroke. A single unit can apply forces of up to 180 metric tons; with the force being proportional to the applied pressure. This can be hydraulic (FSK series) or pneumatic (FSKP series). Split functionality is superior! Generate fast and powerful...

PowerStroke - advantages Advantages at a glance Press with PowerStroke The PowerStroke is the smarter and better solution! It generates the short power stroke rigth there where it is needed. As a consequence, the opening and closing strokes can be carried out by a compact, specialized drive system. Quickly and efficiently. Due to its intelligent design, the PowerStroke closes the mold by pulling instead of pressing as a press cylinder would do. Therefore the closing force only affects the mold not the complete machine frame. The press can be designed in a more compact way. The compact...

PowerStroke - products The operating principle: ingeniously simple or simply ingenious PowerStroke FSK hydraulic ■ SiForce Technology ■ Working forces of up to 180 metric tons with one unit ■ Rod diameters of up to 200 mm ■ The PowerStroke clamps a smooth, round rod and pushes it with great force at a defined rate of travel (short stroke). ■ During the opening and closing of the mold, the PowerStroke is open (pressure at port L) and does not interfere with the movements. ■ When the mold halves are in contact, the PowerStroke locks onto the rod using the proven principle of self-intensifying...

PowerStroke - applications Generate horizontal force? No problem! The PowerStroke can operate vertically as well as horizontally. In both cases, at first a relatively big stroke has to generated with small forces. Then, for the last millimeters, great force has to be applied. After presenting the PowerStroke to our customers, we often hear: "If only I had known about this earlier!" Now you know. From now on, using the PowerStroke, you can design your machines in a more creative way. Testing On one test rig, components of different sizes can be tested, for example: ■ Leak testing ■ Load test...
