Frequently Asked Questions

What is a challenge?

It is our goal to increase the exchange of knowledge among engineers of our portal PARTcommunity. As a benefit for our active community members we have created several challenges together with the support of numerous component manufacturers, which are awarded with interesting prizes.

How does it work?

Follow the description and tasks of the respective engineering challenge. Post your contribution together with a photo or screenshot to the defined section within the PARTcommunity portal. After the process is finished an independent jury will figure out the winner and notify him.


We'd be more than happy to answer any questions you have per email under Marketing@cadenas.de or via telephone under +49 (0)821 2 58 58 0 - 0.
