Archers hit the bull’s eye with Covestro polycarbonate nocks

Archery has undergone a transformation from one of the oldest hunting methods in human history to a precision sport that is also frequently an element of major sporting events.

For more than 30 years, Werner Beiter has manufactured nocks, the notched tip of an arrow, with Makrolon® 2805 polycarbonate from Covestro.

Task

In archery, bow and arrow technology is continuously evolving. That also applies to the nock of an arrow – the notched tip that briefly clasps the bowstring before the tension of the drawn bow is released and the arrow takes flight.

Challenge

Werner Beiter is considered a pioneer in precision injection molding and has gained an international reputation as a manufacturer of premium archery accessories and parts. For its nocks, the company required a polycarbonate material that provided durability and a range of color options.

Solution

Since 1985, the company has been using Makrolon® 2805 polycarbonate from Covestro for its nocks. With its mechanical strength and specialty colors developed for this application, the polycarbonate is the key to the nocks’ outstanding quality. These products are very highly regarded around the world, which is ultimately due to their remarkable durability, coupled with a visual effect that enables an archer to see the arrow’s point of impact, even from considerable distances.
