Along with mineral water, a whole series of different types of beverage are manufactured industrially and filled in vessels such as bottles, cans or barrels.
After consumption, the majority of empty bottles are returned for reuse. Technical plastics such as POM-C are available in a range of colours and are ideally suited for use as bottle holders and grippers. After sorting, the bottles are cleaned inside and out. Cleaning plants offer a range of application possibilities for plastics: From mechanical parts at the infeed and outfeed to the bottle slide. These can be manufactured from plastics such as PA+MOS, in order to prevent unnecessary scratches on the glass.
When selecting materials for the production of cleaning plant components, the application conditions have to be taken into account (hot water, high water pressure and use of chemicals). PEEK natural and the modified types comply with the stringent demands involved. In the actual filling plants, plastics are used due to their low specific weight and their good sliding properties. Whether quick-change devices, worm conveyors or slide rails, the lightweight materials help save energy and reduce maintenance costs due to low wear. Cast nylon PA6+MOS with its molybdenum disulphide filler combines good damping properties and high strength. In addition, this material offers improved surface hardness and good slide friction properties even in dry running operations. Plastic components are even used for the final process stages. Typical components
include star conveyors in labelling and packaging machines.
