Extrusion International 5-2019

52 Extrusion International 5/2019 FILM EXTRUSION Company ALEKOMachinery – the Russianmanufacturer of equipment for polymers processing –will take part for the third time in the biggest industry showK 2019 inDusseldorf, Germany. In the booth the companywill present the newest inventions created in the linewith the recent trends in the plastic industry The design of this machine lead not to just an adaptation of existing tech- nical solutions of ALEKO company in PE film blowing extrusion, but to a complex modernization of the most parts of the machine. Absolutely new structure screw and die have been de- signed and built. In K 2019 show booth an extrusion line built specially for these tasks will be presented. Visitors could see the line working in four types of Biodegradable materials including Ecovio (BASF), BIO COMP (Microtec), Gemabio (Gema). And they can personally value samples of ready film. The machine is capable to produce film made from different Bio- degradablematerials with the thickness starting from 8 to10 micron. High Speed HDPE film blowing line The design of Extrusion lines working with traditional HDPE also does not stand still and keep on evolving. In addi- tion to thequality of producedfilmmore and more attention is devoted to pro- duction capacity. It means that the task to produce more volume of ready prod- uct in a fixed time becoming to be criti- cal. Existing models of ALEKO extruders are popular in themarket thanks in large part to their high production capacity even in standard specification. But there’s no limit to perfection. In the exhibition visitors will be able to see one more invention of the company – High Speed HDPE film blowing line specially for thin films. The line speed up to 200m / min, and the film thickness from 5 mcm. In the booth visitors could see the extrusion line in work and to see re- sults and parameters online. Automatic Film Thickness Control System ALEKO company is presenting in K 2019 show exhibition the first designed and created in Russia Film Thickness Control High Speed film blowing line working with Biodegradable raw material The production of packaging materials is following the ecology trends. Chang- es influence the wholemarket and now many countries newrestrictions of using of polyethylene shopping bags or even a complete ban of PE bags are impos- ing. This fact is pushing the industry to react and to adapt the packaging ma- terials production by using new biode- gradable rawmaterials ALEKO meeting the market demand have offered a decision by creating a blown film line capable to process modern biodegradable polymers on the base of polylactic acid (PLA) and polymerized corn and potato starch. System. Devise is developed for continu- ous measurement and on-line correc- tion of sleeve type film thickness during extrusion in a real time. Thickness control is made synchro- nously by temperature correction and by correction of airflow rate. Complex approach helps to reduce film thickness tolerance to 70%. Circular system of continuous measure- ment of film thickness made on the base of Kündig (Switzerland) capacitive sen- sor is fixing thickness deflection from set figure. Received by the sensor data is transmitted to controller and special software calculate appropriate algo- rithm of system reaction and needed segment of the film get treatment. Air flow actuators are regularly distributed Highlights in the Film Blowing Technology from Russia High Speed HDPE blown film line ALEKO TURBO Automatic Film Thickness Control System Gravimetric dosing system
