What has become of the manus winners?

The manus award is a joint initiative which the plastics specialist igus announces every two years. More than 3,000 contestants from across the globe have entered the competition in recent years, which honours the creative use of polymer plain bearings in industrial applications. This year, the manus award celebrates its tenth anniversary. A good reason to look back: what has become of the last nine winners and their projects? The Industrieanzeiger made enquiries.

To make sure bottles are cleaned, Krones AG makes bottle cleaning machines for the beverage industry. In the machines, conveyor chains transport the bottle carriers. The bottle carriers go through different treatment areas. The main cleaning takes place in 80°C soda lye. To design the conveyor chains as a smooth running chain even under challenging conditions, Krones AG used plain bearings made from a customised high-performance polymer. Today, the materials iglidur J and iglidur X6 are the best choice to take on all challenges in practice. The lubrication-free and dirt-resistant polymer plain bearings were produced by igus in Cologne with special geometries via injection moulding. They minimise the coefficient of friction of the washing chain significantly and hence increase the energy efficiency and durability of the system. These important criteria led to Krones AG winning the first gold manus award in 2003. We discussed the project with Mr. Michael Siegmund, Head of Cleaning Technology at Krones AG.

Mr. Siegmund, what has happened since you won the manus award?

What is the current situation of the project?

Basically, the machine that won the manus award in 2003 is still being produced today, but in an improved version. The main functions and elements are still the same. We sold more than 500 of this machine type around the world. There are between 400 and 3,000 plain bearings in one machine. The number depends on the size of the system. The service life of a machine is between 5 and 20 years, depending on the operation. We also used proven elements of the bottle cleaning machine for the development of new systems.

Have you worked on new applications with igus since you won the manus award? If so, which ones?

In the area of pasteurisers, i.e. in machines for preserving bottles and cans, rollers made of an iglidur material specifically developed for this application have been used very successfully in the conveyor belts for several years. We also realised further projects with igus plain and spherical bearings in the insertion area of the bottle cleaning machine.

Thank you for the interview.

This year, too, the jury under Werner Götz's patronage will be looking for unique applications with polymer plain bearings. The winner will receive prize money of up to 5,000 euros. For the first time, the contestants have the chance to win a green manus award for the use of plain bearings in a sustainable project. You can find more information at: www.manus-award.com
