Product properties and process optimization in the battery industry
Deformation
Gentle handling of the electrodes and separators by reducing the dynamic and static forces on them by means of optimum dimensioning and distribution of the suction points. Proven lower surface pressure compared to other gripping principles such as elastomer suction cups or Bernoulli grippers.

Contamination
Suction surface made of special material PEEK (polyetherether ketone) minimizes mechanical abrasion and prevents chemical contamination. The high volume flow of gripper also removes particles from the electrode, which are then removed from the working area by exhausting the exhaust air.

Electrolyte Resistance
An important component in every battery is the electrolyte, which ensures the transport of ions between the electrodes. The complex system of solvent, conductive salt and additives can attack components that come into contact with it. Schmalz offers suction cups made of materials resistant to corrosion by electrolytes. Compared with suction cups made of other materials, it can be used for a long time, to improve the productivity and output of the line.
Cleanroom Suitability
Products of Schmalz can be used in mostly every cleanroom class. Together with high level institutes the products of Schmalz have been tested and certified. This certification is based on different regulations and official standards.
