Suction Cup Shapes
Contact Kontakt Suction cups from Schmalz can be divided into universal suction industries. They may be characterized by special properties, such

cups and suction cups for special applications. Universal suction as the handling of thin-walled and greasy body panels in the
cups cover a wide range of requirements. Suction cups for special sheet metal industry or of porous and structured workpieces in
applications were developed to meet the requirements of individual the wood industry.
