Production logistics for aluminium profiles

Intra logistics in the pressing plant

The company, apt Hiller GmbH, is a manufacturer of aluminium profiles, as are used in respect of windows and doors, football goalposts and trade fair stands.

For the manufacture of these profiles a 480° C hot press bar with up to 4,000 tons of pressure is pressed into a mould.The approximately 50 m long profiles are then subsequently stretched, sawn to lengths of 8 meters and placed correspondingly into the transport containers. Depending on the requirements the transport containers run through the further operations of manufacturing: hardening ovens, anodisation, subsequent processing, packing and dispatch.

These are combined flexibly through automatic conveyor technology, crane facilities and a shuttle vehicle.

3 storage spaces of different sizes serve as buffer zones in which the transport containers are stacked.

A particular requirement for the transport system is the coordination between the pressing plant and the anodising plant, which are at 100 m distance from each other.
