Extrusion International 1-2022

21 Extrusion International 1/2022 „ KANSAI HELIOS Group has just expanded its production of coatings at two locations – Helios Coatings Italia and He- lios Coatings Deutschland – using a Coperion twin screw extruder at each site. Two ZSK Mv PLUS extruders with 43 mm screw diameters for powder coating production were installed practically concurrently, one at the Riese Pio X location in the Venice region of Italy and the other at the Buchholz, Germany site. KANSAI HELIOS speci fi cally decided upon Coperion’s twin screw extruder technology, due to its very high dispersion performance, and its suitability to a very broad range of recipes. KANSAI HELIOS values how Cope- rion ZSK extruders ful fi ll very high quality requirements, as well as their ef fi cient operation and fl exible options when manufacturing powder coatings. With these two ZSK twin screw extruders, KANSAI HELIOS is deliberately expanding its powder coating production around a technology that has built in fl exibility for fu- ture challenges. ZSK extruders’ speed, residence time and throughput can be modi fi ed quickly and individually for the requirements of new powder coating recipes. Coperion’s ZSK Mv PLUS twin screw extruders have already been used successfully for manufacturing high-quality powder coatings for many years. Extruders in this series stand out particularly for their deep cut screw channels with a 1.8 Do/Di (outer to inner) screw diameter ratio, re- sulting in a large free screw volume. Powders with low bulk density and poor intake behavior, often used in powder coating manufacturing, can be fed into the process in large quantities. At the same time, thanks to the ZSK Mv PLUS’s twin screws, even recipes with high fi ller content are inten- sively dispersed while still being gently handled. Distribution of individual raw materials in the powder coating premix proceeds reliably and homogeneously. The result is a high- quality powder coating. All of the ZSK extruders’ connections, water supply and ca- bles are protected by easy-to-clean casings and are still eas- ily accessible. The closely intermeshing twin screws ensure optimal self-cleaning in the process section, making recipe changes quick to execute. Coperion has equipped the ZSK 43 MV PLUS extruders for KANSAI HELIOS with a number of smart features to simplify machine operation; both twin screw extruders are oper- ated using the new, user-optimized CSpro control system. Complexity of its user interface is greatly reduced in com- parison to previous versions, without losing any well-known functionalities and it can be operated intuitively by touch. Information can be inserted on demand. The risk of possible operator error is markedly reduced. Additionally, both of KANSAI HELIOS’ ZSK extruders have been equipped with electronically secured maintenance doors at the gearbox lantern. As soon as the extruder’s screw shafts come to a complete stop, service personnel can open the gearbox lantern without tools. The screw shaft coupling can be accessed safely and quickly, leading, for example, to a clear reduction in downtime during machine maintenance and a resulting increase in the machine’s ef fi ciency.
