Packing industry

A world full of possibilities!

Packaging with a demand for form and design

Everthing is possible. Whether round, oval or angular, whether large, medium or small. The special is versatile. Packaging for a wide variety of foods must be user-friendly to handle, have an interesting feel or an unique surface. The design language in terms of look and feel often determines consumer acceptance in just a few secons. No matter whether the contents are pasta salad, ice cream, yoghurt or magarine.

The customer of KAESER Kompressoren is a manufacturer of plastic packaging for the food industry. Here, the complete range of the production chain is handled from a single source: from development and design to prototyping and toolmaking, right through to series production and logistics. In three state-of-the-art production plants, 120 automated injection moulding machines are used to produce state-of-the-art packaging systems for a wide range of applications using the IML (in-mould-labelling) process. This is an innovative labelling technique for plastic packaging. Pre-printed labels are inserted into the injection mould. This means that the labelling process takes place during the production of the packaging, not afterwards. This means there is no need for a seperate adhesive layer. This is because the labels bond directly with the molten plastic when the liquid plastic is injected. After cooling, the label is bonded to the packaging as an inseparable unit. This processing technology creates a 1-substance package that can be recycled.

Challenge

Due to the construction of an additional production plant, which among other things will also house a state-of-the-art high-bay warehouse with a capacity of 19,500 pallet spaces, a new compressed air station must be installed. The new station must meet the high quality standards common in the food industry and be able to reliably and cleanly deliver the compressed air required for production.

The compressed air is used for valve control on the injection moulding machines, for demoulding and for needle control on the injection moulds on the handling robot, at the camera station and during labelling as control air for valves and cylinders and for transporting and ejecting the parts.

Solution statement

  • KAESER Kompressoren installed two KAESER CSD 104 screw compressors, one KAESER CSD 125 screw compressor and one KAESER DSDX 305 screw compressor for this project
  • Three KAESER SECOTEC TF 280 refrigeration dryers provide compressed air drying.
  • The compressed air quality is ensured by the use of two KAESER activated carbon adsorbers and various KAESER filters.
  • The KAESER SIGMA AIR MANAGER 4.0 takes care of the cross-machine control.
  • All KAESER compressors are equipped with a heat recovery system

Customer value

  • The four 12-bar units installed effortlessly ensure are pressure level of 6.4 bar and also offer additional potential for future changes in compressed air requirements.
  • The compressor waste heat is used to heat the entire new plant
