Production logistics for intelligent sheet metal
Earliest possible production start
The company, ThyssenKrupp Tailored Blanks, manufactures tailor-made sheets for the automobile industry. Different sheet strengths or steel qualities are used in these sheets. The connections through laser welding are so precise that the transformation is almost possible in the same way as with non-welded sheets.
The priority target for the new production plant was a swift start-up of the production. It was therefore decided that the production logistics should be developed in stages. First of all the cutting press and the welding machines were equipped with conveyor technology for the transfer of materials.
In the second step the materials flow became completely automatic, whereby the 120 m long high bay warehouse serves as an intermediary store. In the last phase the WMS was connected with the company’s own SAP/R3 system. The development of the automation in several steps also made major requirements on security technology
