Extrusion International 2-2019

31 Extrusion International 2/2019 planning process, prepares the spec- ification, monitors the construction and attends assembly and launch. Fabrication and assembly is done by my Turkish partner enterprise. There we also test the equipment before shipment. The main components are obtained from Europe to ensure quality. Therefore is my catchphrase, “Developed and engineered in Aus- tria, manufactured and assembled in Turkey”. That sounds like you have direct contact to the processor. Is that your main customer base? Dobrowsky: Yes, I transact approxi- mately 80 % of my projects directly with the pipe producer, who ap- proaches me with his individual task. Often being small and medium-sized companies, who approach me with various questionings. I, for example, designed a four-layer cross head to apply a spiral color stripe inside a three-layer pipe, found a space-sav- ing solution to convert a single to a three layer pipe extrusion line and engineered a moveable cross head that is able to be used instead of three single heads with an extreme- ly high range of pipe diameters. But you also work for the big play- ers? Dobrowsky: Yes, of course. Big pipe producers like Simona und Wavin are part of my client base. I signed non-disclosure-agreements with all of my clients. The diversity of projects and clients is what makes my work exciting for me. All the projects I complete make me keep refining my technical know-how, and stay up to date with technology, which is very important for perfect counseling. In the beginning years of your engi- neering office the majority of your projects were done for mechanical engineering companies, weren’t they? Dobrowsky: That is true. In the first years my work consisted up to 80 % of projects with and for pipe extrusion manufacturing compa- nies. Today they only make up 20%. Nonetheless they still are interest- ing projects I enjoy. In the last years I’ve worked with major pipe ex- truder manufacturers like Windsor, Cincinnati Milacron USA, Liansu, Tecnomatic, Mikrosan or Rollepaal reworking upgrading extruder and pipe head series. In addition to that I advised the companies concerning optimal installation configurations. What is the client’s main advantage in commissioning you? Dobrowsky: The main advantage is the holistic consultation. I take care of every detail like space require- ment to shipment and I’m highly focused on the client’s individual question. A workwise like this is only possible as a sole entrepreneur. An- other advantage is my cost-effective business structure. The clients re- ceive special solution at an attractive price. Industry 4.0 is one of the omnipres- ent topics of the plastic sector. Do you notice that? Dobrowsky: Yes, I do notice it. Al- though I honestly have to say that industry 4.0 in the pipe sector is still a topic of the future. Neverthe- less, even now, all of the extruders of the Conextru series are industry 4.0-ready. I am working with ABB control, which is network compat- ible. The special feature of our con- trol systems is the ease of operation. The operator needs no training. What are your future career plans? Dobrowsky: I would like to work in the plastic sector for another ten years. The challenges of difficult questionings and finding innova- tive ways are very enjoyable for me. With my network of European com- ponent suppliers it is possible to re- alize almost every mechanical engi- neered solution. We wish you all the best for your way!
