BC Extrusion: Operator support is becoming increasingly important

In this interview with VDMA for the upcoming K 2025, Dr. Henning Stieglitz, CEO and CTO at BC Extrusion Holding GmbH, discussed about recycled materials, artificial intelligence, and circular economy in the plastics industry.

Dr. Henning Stieglitz, CEO and CTO at BC Extrusion.

 

Dr. Stieglitz, where can efficiencies still be improved in plastics extrusion?

 

Dr. Stieglitz: There are four key factors for us: the use of materials, the line speed, the use of energy and the use of recyclates. The biggest driver is the use of materials. The aim is to keep the tolerances as low as possible so that the customer can go to the lowest limit, and at the same time achieve the highest savings in terms of materials. The ideal scenario would be to get 100 kg of pipe or window profile from 100 kg of material. 


As a rule, you always have to use a little more. The use of recyclate is a comparatively recent topic and depends heavily on the type of application. It is slowly gaining momentum in the pipe sector, and the use of recyclate has also been increasing in the packaging sector for years.

 

Is it difficult to minimize the use of materials and at the same time use recycled materials?

 

Dr. Stieglitz: Yes, because the properties of recycled materials are generally not as consistent as those of virgin material. This is an issue we have been increasingly addressing in recent years: how customers can manufacture the best possible product from post-consumer material – using as little material as possible and, of course, with as little energy as possible. This is a challenge that we are increasingly focusing on in our machine concepts.

 

Are you already using artificial intelligence?

 

Dr. Stieglitz: Battenfeld-cincinnati would like to use AI in particular to support operators and make their daily operations easier. For instance, an AI that tells the operator when an error occurs, what the cause is, and how it can be rectified – or that shows that the operational energy consumption is not optimal, and makes suggestions on how to improve it. 


To do this, you have to record certain error types, and store corrective measures that can then be retrieved from the system. This operator support is becoming increasingly important. We are endeavoring to provide systems that are very easy to use and very supportive. To do this, we will need to utilize AI.

 

Is this a step towards the "unmanned machine"?

 

Dr. Stieglitz: Absolutely. Our Fast Dimension Change (FDC) system, for example, makes it possible to adjust the dimension of a pipe during operation with the help of the control unit and its built-in components. In principle, there are memorized recipes: you press a button, and the system changes the wall thickness and pipe diameter. Only one person is needed to make the change on the control unit. The machine does the rest. There is something similar for simple tasks in production. 


I can't say whether there will ever be a fully automated line. There will certainly always have to be a supervisor, but many other tasks will be automated.

 

Has the circular economy taken a back seat in the face of economic problems?

 

Dr. Stieglitz: It is still the case that using post-consumer materials generally costs more than using new materials. You have to ask yourself who is going to pay the additional costs in the end. There are already very good solutions for recycling. 


For PET bottles, the cycle in Germany is almost closed. In some respects, however, we have overshot the mark. Coated paper has recently been heavily promoted as a packaging material in some areas. The paper used here is extremely highly processed, and the composite is almost impossible to recycle.

 

Could the circular economy become an export hit?

 

Dr. Stieglitz: Well, it won’t be everywhere, it's simply a matter of cost. If it is already difficult to pass on the higher costs of recycling to the products here, then how would that be possible in developing countries? The priorities there are different. The aim in those countries is to ensure that all people have access to food, and that food does not go to waste during transportation. However, it will be possible to tackle individual aspects of the circular economy, such as collection systems for example.

 

What do you expect from the upcoming K?

 

Dr. Stieglitz: I am sure that K will be very well attended. I expect more clarity on the future tariff agreements with the US by October. I think that once the uncertainty has subsided, visitors will want to see new things again, innovations that people will want to invest in. In addition to digitalization in general, I expect topics such as operator support via the control system to be a focus, plus of course the efficient use of resources.
