An introduction to optimization in polymer processing based on extrusion. Described methods are universal and can be applied in other polymer processes. We start from definition than optimization methods, how we acquire input and output date and for the end input and output data in extrusion. Every task to do we can present as an answer. Optimization would be looking for the best (extremum) in the possible answers with assumed criteria, defined target function (e.g. max. output , min. power consumption ). For small area statistical methods like regression analysis when full area is scanned is applied. For large area artificial intelligence methods have to be applied, e.g. neural networks, genetic algorithms and hybrid methods (connect more than one). Extrusion optimization is complex. There are many optimization criteria, they can be conflicting like max. output and min. power consumption and many input data ( geometrical, process parameters ). We have two ways of collect...

After plastic cards it is time to polymer banknote. For hundreds of years, banknotes have been made from rag-based paper. Today, banknote issuers are faced with the challenge of increasingly sophisticated counterfeiting techniques and there are serious doubts that paper remains a viable material for secure banknotes. CSIRO’s expertise in polymer and synthetic chemistry was used to develop a non-fibrous and non-porous plastic film, which the banknotes are printed on. This substrate gives high tear initiation resistance, good fold characteristics and a longer lifetime than paper. The substrate and the specially-developed protective overcoat prevent the absorption of moisture, sweat and grime so that the polymer banknotes stay cleaner. CSIRO has also developed a variety of overt and covert security features for use on polymer banknotes. These security features are produced from a combination of spectroscopic techniques, synthetic chemistry, nanotechnology, surface science microstructu...

For full story please visit University of Waikato web site. There will be no comment this time. The new process, developed over two years by University of Waikato chemical engineer Dr Johan Verbeek and Masters student Lisa van den Berg, can turn animal protein waste like blood meal and feathers into a biodegradable plastic using industry-standard plastic extrusion and injection moulding machinery. A process developed at the University of Waikato will allow animal waste to be turned into useful and biodegradable plastic. "Proteins are polymers so we know they can be turned into plastics," Dr Verbeek said. "Plant proteins successfully been used to make bioplastics, but animal protein has always ended up gumming up the extruder. The process we've developed gets round that problem. People said it couldn't be done, but we did it!" It's a source of plastic that doesn't rely on petroleum, so we also see it potentially being blended with conventional plas...

Just few words about 12th International Fair of Plastics Processing Plastpol which took place in Kielce, Poland 27-30 May, 2008. Sorry but there will be no sum up and statistics and even my own consideration the next time I will be prepared better. There are only two pictures of extrusion machines. The picture below presents machines from polish plastics machine manufacturer ZMCh Metalchem Gliwice one of it with high torque synchronous motor . PS. Have you visited Plastpol ? Please share your impressions.
