Our product range includes a variety of suction cups with various shapes, sizes and materials, providing the right suction cup for every application. Suction cups consist of a elastomer part and a connection nipple.
Special grippers can be used for applications in which regular suction pads cannot generate a vacuum. Schmalz offers a variety of special grippers with various shapes, sizes and principles of operation.
Area gripping systems and end effectors are gripping systems that can be attached directly on the robot. Area grippers are universal and are used in a huge range of robot applications. Vacuum end effectors are easy to configure from the modular system. They are particularly suitable for processes in the packaging industry.
Schmalz offers a wide range of mounting possibilities for integrating suction pads or special grippers into a vacuum system.
Vacuum generators provide the required vacuum. The vacuum is generated either pneumatically (ejectors) or electrically (pumps, blowers). Pneumatic vacuum generators implement short cycle times and can be integrated directly into the system due to their compact and lightweight design. Ejectors offer intelligent functions for energy and process control. Electrical vacuum generators are used in applications when compressed air is not available or if very high suction capacities are required.
Valves are used to control the vacuum as well as the compressed air. The right valves can increase both the process reliability and the cost-effectiveness of the vacuum system.
Devices for system monitoring are crucial to ensure the safe operation of a vacuum system. Schmalz offers a wide range of switches, measuring and control devices, as well as warning devices.
Filters protect the vacuum generator from contamination. Vacuum distributors, hose lines and connections complete the vacuum system and connect suction pads to vacuum generators.
With certified courses, seminars and customer-specific training sessions on all topics within vacuum technology and efficiency, Schmalz provides expertise that is tailored to the exact requirements of your company.

Clamping Solutions for CNC Machining Centers
Vacuum clamping technology for wood processing is essential for efficiently setting up console table, grid table and flat table systems. Existing machining centers can be easily modernized with the Innospann clamping system. The Schmalz clamping equipment lets you clamp both narrow workpieces and workpieces made from solid wood. The Multi-Clamp is the perfect tool for manual fixing of small and medium-sized workpieces.
Schmalz clamping solutions enable the quick and uncomplicated setup of CNC machining centers with flat table. First the vacuum blocks and then the workpiece are fixed for machine processing via two independent vacuum circuits. Schmalz provides vacuum blocks with a hose connection for universal flat tables and a hose-free version for flat aluminum tables with an integrated vacuum distribution.
The vacuum clamping system Multi-Clamp is the perfect tool for quick and flexible clamping of small and medium-sized workpieces. They can be fixed in any position and processed all-round. The Multi-Clamp is portable and can be used in a variety of industrial, workshop and building-site contexts.
Very narrow and curved parts can be clamped easily and reliably with mechanical clamps and Adapter-Plates from Schmalz. Narrow suction surfaces enable the precise positioning of the vacuum block along the workpiece contours, holding the workpiece in place. The workpiece is mechanically clamped firmly in place using the clamp.
Schmalz vacuum clamping technology provides an efficient solution for clamping workpieces made from solid wood. The clamping equipment lets you process workpieces on consoles with single and two-circuit vacuum systems quickly and safely.
Replacement suction plates for vacuum blocks in different sizes for various machine table systems. The top and bottom suction plates can be replaced quickly and easily.
Schmalz clamping solutions ensure flexible and efficient production processes in glass working. Suction cups with special friction pads are wear resistant and guarantee precise results, even in challenging operating conditions. Schmalz developed the Quick-Change System SQC especially for machine tables with screw-attachment suction cups. The quick-change suction cups offer minimal setup times and maximum flexibility.
The Schmalz Matrix-Plate guarantees minimal set-up times when clamping flat workpieces with flat undersides on CNC machining centers. Using the vacuum clamping system, even components that are difficult to clamp mechanically can be secured precisely, quickly and without distortion. Flexibility is increased again when combined with the Innospann Steel-Plate. Productivity and set-up times can be further optimized, particularly when workpieces are changed frequently.
Workpieces with uneven, rounded or curved contours present a new challenge for clamping technology. With the Schmalz Basic Holding Fixture, complex components for CNC machining and measurement processes can be clamped without a problem. With the Suction Cup Balance SSCB, Schmalz has developed both a clamping system with precise positioning for 3D free-form surfaces and a gripping system equipped for automatic setup and simultaneous gripping.
The vacuum generation contributes significantly to process reliability when clamping workpieces on CNC machining centers. Schmalz has developed vacuum generators specially to meet the demands in the metal and glass working industry. These systems not only prepare the material, but also monitor and separate liquids or chips that have been sucked in.

The calculated theoretical holding force corresponds to the force that the suction cups must create in order to handle the workpiece safely. To select the suction cups, one must also take the ambient conditions and the application into consideration. The selection of the suction cups usually takes place based on the following criteria:
Application: Multi-shift operation, service life, chemically aggressive environment, temperature, etc.
Material: Suction cups made of different materials are available to meet the requirements, such as those particularly suited for smooth or rough surfaces, oily or very fragile workpieces, anti- static suction cups for electronic components, suction cups leaving few marks for fragile plastic parts, etc.
Surface: Depending on the condition of the surface, we recommend suction cups in specific shapes. You can select from flat or bellows suction cups with different sealing lips and sealing edges in different shapes and geometries.
This suction cup is a cost-efficient solution for handling smooth, level workpieces.
To solve the example, the calculated theoretical holding force can be applied by one suction cup or distributed among several suction cups. The number of suctions cups used depends on the respective application.
For the steel sheet (2,500 x 1,250 mm) from the present case, one would usually use six or eight suction cups. The most important criterion for the number of suction cups in this example, is the flexing of the steel sheet during transport. Depending on the number of used suction cups, the required diameter of these suction cups changes.
Calculation of suction force FS [N] for individual suction cup
FS = FTH /n
FS = Suction force
FTH = Theoretical holding force
n = Number of suction cups
FSc = 1,822 N / 6
FS = 304 N
According to the technical data for the suction cup PFYN, one needs 6 x PFYN 95 NBR with a diameter of 95 mm and a suction force of 350 N each.
FS = 1,822 N / 8
FS = 228 N
According to the technical data for the suction cup PFYN, one needs 8 x PFYN 80 NBR with a diameter of 80 mm and a suction force of 260 N each.
Six suction cups of type PFYN 95 NBR
With a sheet thickness of 2.5 mm, six suction cups ensure a secure sheet pick
