Poland, Skawina, 30 July 2021

The secondments to ZAM that started in March 2020 have finally been completed.
The secondments were in line with the design solution plan according to the WP3 work plan: “Preparation of the automation and control system”. In collaboration with project implementers from Zamak Mercator sp. z o.o. and academics from the University of Minho and Technical University of Kosice, the objectives resulting from Task T3.2 were achieved, namely the automation system controlling the entire extrusion system of the new machine was developed and prepared, thus automating the process in real time.
The aim was to verify the functionality of the PLC system in the new machine, in order to check its hardware and software flexibility, i.e. the effectiveness of changes to the program during the process of using the machine. During the verification of the PLC system, various communication modules were tested to ensure communication with other systems, in particular with systems for visualisation and control of technological processes. It was therefore a question of verifying the input and output signals using the imaging process.
Various variants of correct operation of the automation system have also been designed and verified as regards detection of temperature indications in the melting chamber, obtaining correct material homogenisation, and others.
In cooperation with Zamak Mercator sp. z o.o. company, programmable logic controllers (PLC) and Human Machine Interface with touch panels, as well as software for control and visualisation of extrusion process parameters in combination with a security system have been developed. Thanks to the correctly set up PLC system, automation of the system was achieved, which is important for achieving maximum efficiency of the production process on the extruder.

As a result of the analysis and brief discussion, the vital extruder elements that will be made in the prototype were pre-selected. Then, Mr Lino Costa z UMI gave a lecture concerning „Multiobjective optimization”, in which he stated that the engineering problems often have several conflicting objectives. In particular, the optimization of an extrusion process or the design of an extruder is a hard task since it involves several important objectives to be optimized. The goal is to find the Pareto-optimal set, i.e., the optimal operating conditions and the geometrical parameters of extruders that yield the best performance for the manufacturing of a certain product.  This optimization problem involves a considerable number of objectives. Multiobjective optimization is a very challenging research endeavor. Advantages, drawbacks and limitations of the classic scalarization methods and evolutionary algorithms were discussed. The problem of handling many objectives and the decision-making process were also addressed. Multi-objective approaches are valuable tools to assist the decision maker to select, from the Pareto optimal set, the more suitable solutions for the screw extrusion process. Then, Mr Antonio Gaspar Cunha presented two lectures entitled “Modelling of the single screw extrusion process” and “Modelling and Optimization: Cases studies”. He showed that the most of the real optimization processes are multi-objective. This is also true when dealing with polymer processing technologies, where it is necessary to determine the operating conditions and/or the system geometry automatically. For that purpose it is necessary to couple modelling routines with optimization routines capable to deal with the multi-objective nature of the problems. In this lesson, multi-objective routines were used to optimize the process of scaling-up in the case of single screw extrusion and on the optimization of the operating conditions and/or screw configuration for the case of co-rotating twin-screw extruders. The results obtained show the validity of the approach proposed. All materials are available in the form of relevant reports and deliverables available from the Project Coordinator, on the Participant Portal website and on the Newex project website, and some of them in the form of quizzes.

On 13 April prof. E. Spisak from TUK talked about the field of transport phenomena as the basis of modeling in polymer processing. This workshop lecture presented the derivation of the balance equations and combined them with constitutive models to allow modeling of polymer processes. The chapter also presents ways to simplify the complex equations in order to model basic systems such as flow in a tube or Hagen- Poiseulle flow, pressure flow between parallel plates, flow between two rotating concentric cylinders or Couette flow, and many more. These simple systems, or combinations of them, can be used to model actual systems in order to gain insight into the processes, and predict pressures, flow rates, rates of deformation, etc. When solving flow and heat transfer problems in polymer processing, the conservation of mass, forces or momentum and energy must be satisfied. Momentum and energy balances, in combination with material properties through constitutive relations, sometimes result in governing equations that are highly non-linear. This chapter presents the balance equations, making use of constitutive relations presented in this lecture.

Ing. Ivan Gajdos from TUK, during his presentation on 13.04.2017, talked about CAx solutions for polymer processing technologies. While the extrusion process has been utilized for commercial products since the mid-1800s, designing, modeling and computer simulation is merely in its infancy. However, the advantages offered by CAx technologies make it well suited to further advance the extrusion process through the next decades. Simulation and CAE of the extrusion process and equipment permits a systematic design rather than ad hoc designs based solely on experience. While traditional experimental design of the extrusion process is focused on producing an acceptable product, oftentimes there is no explicit understanding of how process variables interrelate with one another and affect the final extrudate.  Simulation also offers significant advantages in the design of extruder screws and mixing devices. Computer simulation allows an engineer the possibility to x201C;try out x201D; numerous new designs on the computer rather than expend time and costs associated with developing and testing a prototype. With the increasing requirements to decrease costs, improve product quality, and increase productivity, CAx solutions provides an important tool to improve quality and throughput and, thus, profitability.

Prof. František Greškovič from Technical University of Košice during the seminar which was held on 13.04.2017, entitled “Mechanical properties of PA6/MMT polymer nanocomposites and predictions based on the content ofnanofiller” and dedicated to the members of NEWEX project, presented standard methods for material testing. Creating new polymers with desired properties is now more difficult, so there is great place for the modification of known thermoplastics with the addition of fillers. With conventionally used fillers such as talc, calcium carbonate or glass fibers the normal degree of filling is up to 40%. New nanocomposite fillers can improve all kinds of properties with a small degree of filling. This study is aimed at the improvement of basic mechanical properties of well-known polyamide 6 (PA6) thermoplastic with the addition of three different types of nanofillers based on montmorillonite clay. Two fillers Cloisite 30B and Cloisite 93A were organically modified, while filler Cloisite Na+ was in its pure form.

The theory that underlies the discussion of business perspective is the open innovation model by Henry Chesbrough. According to the model, companies both license out the solutions they developed to other businesses (e.g. by setting up spin-off companies or licencing technologies) and licence in technologies when they need solutions they have not developed within their facilities. During the training the basic legal frameworks of technology transfer are discussed and presented.
One of the most important aspects of technology commercialisation is managing intellectual property rights. The training provides the most important characteristics of copyrights, patent regulation and registration procedures for trademarks and designs. Basic regulations concerning UE and national regulations are presented and specific examples based on case studies are discussed.

Lublin: 14 February 2017

On 14.02.2017 Ms Karolina Głogowska gave a talk on Micro-extrusion process at the Lublin University of Technology. Constant progress in science leads to developmental changes in technology. One manifestation of those changes is the introduction of new, improved machinery, equipment, tools and technologies into the production process which can be used to manufacture better quality products with new, hitherto unknown functionalities. This progress has not left unaffected the polymer processing technology, in which one of the trends is to miniaturize both equipment and products. Examples of miniaturization include processing procedures such as micro-injection moulding or micro-extrusion performed using micro-injection moulding machines and micro-extruders.
Micro-extrusion is the process of obtaining microtubes of a simple or complex cross section which are used for high-precision transfer and protection of different kinds of media. In this process, it is possible to obtain tubing of interior diameters and wall thicknesses as small as 0.1 mm and 0.05 mm, respectively. Micro-extruded tubing such as micro catheters and peripheral intravenous cannulas are applied in micro-fluidics, pediatrics and micro-analytics. The present work reports the results of granulometric tests of micropellets produced by micro-extrusion with cold pelletizing as well as strength tests of microrods of different diameters. The experiments were performed using a standard twin-screw extruder and low-density polyethylene.

During the Workshoop on 14.02.2017 within T 5.1a, Mr Łukasz Majewski from Lublin University of Technology gave a lecture Kinematic activation of the barrel. During his presentation he showed that there are currently many modern methods of polymer processing and also a lot of unconventional construction designs of polymer processing machines. One of the many aspects of designers’ interest is the construction of the barrel of the plasticizing system. Łukasz Majewski showed the possibility of the kinematic activation of the barrel by placement of the rotary sleeve in selected heating zones of the plasticizing system. The outline of the rotating sleeve structure was described, including known construction variations such as grooves geometry and rotation direction. On the basis of the conducted research, the influence of the counter-rotating sleeve location and rotational speed on the extrusion process efficiency was shown. He also discussed the changes of the selected process parameters such as temperature of the barrel wall, polymer pressure, mass flow rate of the polymer and specific total energy consumption. Studies of the selected properties of the extrudates were also presented, to determine the influence of the rotating barrel sleeve on the polymer basic properties.
