APSOvib®: Customized elastomeric mounts for wind turbines
Alternative energy from wind has grown tremendously in recent years, with global
installed capacity growth of around 30% per annum. In 2008, the Angst + Pfister
Group decided to develop proprietary industrial components designed to specifically
meet the needs of this rapidly evolving market.

Accurate timing belts perfectly positioned for the packaging industry
Rychiger AG develops and manufactures machines for the production of coffee
and tea capsules. The prefabricated capsules must be moved into exact position
at individual processing stations such as filling and sealing stations. The use
of custom-made timing belts designed by Angst + Pfister makes it possible to meet
these precise positioning requirements.
