All Plastiblow blow molding machines are highly customizable, and this willingness to create tailor-made products has proved essential to penetrate highly specialized markets, such as the production of technical items. The extrusion-blow molding technology is spreading among the production methods of technical articles, under the pressure of at least 3 determining factors: the reduction in the cost of the piece produced; the flexibility of the production process; recyclability. For technical blowing, the parison transfer models are interesting where instead of having a mold that moves from the extrusion station to the blowing station, a gripper is used to transport the parison from the extrusion head into the mold. The elimination of the translation of the mold holder carriage involves some significant advantages, such as lower energy consumption, the absence of vibrations and the reduction of the cycle time when empty; furthermore, the arrangement of the closing unit allows to place blowing nozzles from several parts of the mold and to mount particularly high molds. These characteristics make these blow molding machines particularly suitable not only for elongated technical items (tubular or bellows sheaths for shock absorbers, air or water ducts for cars), but also for production with multiple cavity molds arranged vertically along the parison axis. An interesting field of application of technical blow molding is that of household appliances, where suppliers of the main manufacturers increasingly prefer Plastiblow blow molding machines . With the PB10000 / CF blow molding machines with parison transfer, for example, polypropylene spheres with a diameter of 50 mm are made with molds with 15 cavities, thus achieving very high productions. All the programming and control functions are managed by a PLC through an operator panel: the sequence times of the machine, the thermoregulation temperatures, the thickness profiles of the parison and other functions can therefore be displayed and programmed, through various dedicated pages. ; also available are synoptic panels in videography, diagnostic pages and statistical control functions of the production. Always using a model of blow molding machine with parison transfer equipped with upper and lower cutting groups, pipes for the building industry with a length of up to 500 mm and diameters of the order of 130 mm are produced. Un altro tipico campo di applicazione del soffiaggio di articoli tecnici dove Plastiblow vanta una interessante competenza è quello dei componenti in TPE per l’industria automobilistica, dove coprigiunti e parapolvere per ammortizzatori, originariamente in gomma, vengono sempre più spesso realizzati con elastomeri termoplastici di varia provenienza. Ancora per il settore automotive Plastiblow ha fornito interessanti soluzioni per la realizzazione di tubi parapolvere in HDPE o PP. In questi casi il rapporto fra lunghezza e diametro del tubo è elevato e se gli spessori del parison non sono costanti può risultare problematico il taglio per la finitura del pezzo in macchina. La qualità delle teste di estrusione in questi casi si è dimostrata molto importante per garantire una produzione costante e senza inceppamenti. Recently, blow molding machines have also been supplied for the production of silicone cartridges, an article that requires in addition to the cut for the opening of the tube at one end, a particular finish at the other end with the creation of a hole inside which the spout is inserted. .
