Steel tubes can be drawn effortlessly with the old but well-maintained machines at P+P’s original plant. The systems now work in a mechatronic network. This allows for continuous monitoring and optimization of processes.

Optimized processes in tube production

Poppe + Potthoff Präzisionsstahlrohre is an active partner in the technology network 'it's owl' (Intelligent Technical Systems OstWestfalen-Lippe). Gradually, the "old treasures" of the historically grown machine park are now being prepared for industry 4.0 – with success.

Poppe + Potthoff's original plant, which was founded in 1928, produces seamless as well as welded and refined precision steel tubes in the tightest tolerances. Customers from the automotive industry, measurement and control technology, conveyor technology as well as tool and machine building have high and diverse requirements.

"The tubing plant has always been designed for multi-variant production," explains Bengt-Henning Maas, Head of the Tubular Components Division at P+P. "However, the potential of networked manufacturing can only be exploited by means of modern measuring and control technology. It helps us to become even better, more flexible and more efficient."

Within the framework of the transfer project ‘it's owl-TT-InveRse', Poppe + Potthoff worked with the Fraunhofer IEM to develop a mechatronization concept. The focus lay on the detection and prevention of instable process conditions, which could lead to damage to the tools or the product.

Critical process states were eliminated on the prototypically converted pilot machines. Poppe + Potthoff expects annual savings in the five-digit range through these optimizations. The developed process and automation knowledge is now being transferred successively to other systems.

For more information, please see the "it's owl Annual Report 2016" and the presentation from the “it’s owl Best Practice Day” (in German only).

Systematic: At first, all processes were analyzed, interdependencies determined and potentials evaluated. On this basis, the measuring and control technology at Poppe + Potthoff’s tubing facility is now being modernized step by step.
