New dimensions in extrusion / Christoph Dohm in KUNSTSTOFFE INTERNATIONAL, Vol. 109, N° 12 (12/2019)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 109, N° 12 (12/2019) . - p. 19-22 Titre : New dimensions in extrusion : New and further developments focus on quality and efficiency Type de document : texte imprimé Auteurs : Christoph Dohm, Auteur Année de publication : 2019 Article en page(s) : p. 19-22 Langues : Anglais (eng) Catégories : Extrudeuses Innovations Matières plastiques -- Extrusion -- Appareils et matériels Salons professionnels Index. décimale : 668.4 Plastiques, vinyles Résumé : The highly diverse offering at K 2019 ranged from ingenious detailed applications to complete solutions that encompass the entire process. In the extrusion sector, the topic of the circular economy was very much in the shadow of developments relating to Industry 4.0, although some exhibitors still managed to demonstrate impressive dimensions and production speeds. There were also advances in metrology that will allow progress to be made in quality assurance. Note de contenu : - Bigger and faster - Digitalized across the board - Inline quality measurement - Fig. 1 : PowerCast XL : faster product changes lead to higher productivity - Fig. 2 : Digi.Line : an example of networking and automation in the field of extrusion - Fig. 3 : First steps toward automated optimization : simulations can improve the speed distribution in the melt even before the mold - Fig. 4 : Inline measurement witht the Centerwave 6000 Next "to the pipe head" - Fig. 5 : Novel inline quality control for compounding dyed recycled material En ligne : https://drive.google.com/file/d/1W9vpXhDS3ty5YwYo7A_Xrv9vF5WxKnyt/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=33713 [article]

When less is more / Christoph Dohm in KUNSTSTOFFE INTERNATIONAL, Vol. 111, N° 8 (2021)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 111, N° 8 (2021) . - p. 24-29 Titre : When less is more : Blow film and flat sheet film extrusion trend report Type de document : texte imprimé Auteurs : Christoph Dohm, Auteur Année de publication : 2021 Article en page(s) : p. 24-29 Langues : Anglais (eng) Catégories : Films plastiques Matières plastiques -- Extrusion Matières plastiques -- Recyclage Polyéthylène Index. décimale : 668.4 Plastiques, vinyles Résumé : In the interest of sustainability, film extrusion plants have to process recycled materials and also produce recyclable products. Monomaterial products and a plant layout optimized for the products are the current trends. A multilayer structure as such does not pose a problem for recycling as long as all layers are made from the same class of plastic. Digitization continues to be an important driving force as digital tools contribute to solving the problems that need to be overcome. Note de contenu : - Topics that Gained Importance in Recent Years - Current Product Highlights - Support for Rapid Material Changeovers - Digital Platforms Are in Demand - Composite Film versus Recyclability - What matters in systems engineering - What will gain importance in the future - The race to the first full PE film with barrier function - Figure : In the Reifenhäuser EVO Ultra Stretch line, the PET layer is replaced by stretched PE. The stretching unit is positioned directly in the outfeed En ligne : https://drive.google.com/file/d/1YvCd-9wHa1P7_Z2o_5rS5V2yEvB-mC9s/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=36731 [article]
