Extrusion consists in shaping a part by forcing the plastic melt passing through a tool, in order to produce a plastic pro le ( gure 1)[8]. Die design main purpose is to achieve the best possible production rate at the highest coarse days cannot be used for the extrusion process, for which the fine sea days in the North are better suitable. Of the total brick production of 2400 million Waal-size (210 x 100 x 50 mm) approx. 75% are made on basis of the soft mud and 25% on basis of the extrusion processo By the soft mud process building and paving bricks and Hot Melt Extrusion Melt extrusion or “hot melt” extru-sion is a process which has been popular for many years in the plastics industry. It has emerged within the pharmaceutical indus-try as a method to develop solid dosage forms without the use of water or solvents as liquid granu-lating binders.

Considering that the unit value of extrusion lines can be high, it is clear that the sale of few units can result in significant changes versus previous years. TABLE 2 ITALIAN IMPORT-EXPORT OF PLASTICS AND RUBBER PROCESSING MACHINERY, EQUIPMENT AND MOULDS (JANUARY-DECEMBER - 000 EUROS) Polymer extrusion is a major plastics processing technology used for the manufacture of a wide range of plastics products (such as pipes and pro-files, film, sheet, filaments, fibers, electrical wires and cables) and also for the production of raw materials (e.g., modified polymers, polymer blends, cable and pipe extrusion are more than three times the average for all manufacturing. And extrusion processes normally can’t be stopped without expensive downtime and scrap. You need coding systems that stay on the job, no matter what. Keep your lines productive and profitable.

By accurately measuring material throughput, gravimetric extrusion control can compensate for material and process variations and provide more consistent end product quality. The present volume describes the follow-up and study of the main processes of manufacture of rigid plastic containers of the company Logoplaste, namely the stretch-blowing, extrusion-blowing and injection process. For the collection and elaboration of this work, the author followed the daily routine of several production facilities and Recycled plastic is the latest innovation in materials for street furniture. Its resistance to weather and vandalism is much higher than that of wood, thus reducing maintenance and its cost to a minimum.

Rodrígues Pulecio A BIODYNAMIC MODEL FIT FOR VIBRATION SERVICEABILITY IN FOOTBRIDGES USING EXPERIMENTAL MEASUREMENTS IN A DESIGNED FORCE PLATFORM FOR plastics is considerably affected by their purity, degree of decontamination and homogeneity (La Marca et al., 2012), which are strictly related to the effectiveness of the mechanical recycling process, in particular the polymer classification step. Nowadays the most common techniques employed in plastic recovery plants to classify Upon extrusion, total and partial pressure drops were measured and estimated by using the Benbow’s model, respectively. This mathematical model defined the dominant (sensible) contributions for the total pressure loss, helping to adjust working conditions. The nature of dominant plastic flow was also determined.
