Extrusion 8-2017

80 kompakt Extrusion 8/2017 Promixon S.r.l. www.promixon.com testing and production, Guill built its own rheology lab in their facility in West Warwick, Rhode Island, USA. The lab features several key machines that en- sure optimum results, when testing ma- terials, especially new compounds to be extruded. The testing equipment in- Guill Tool, manufacturers of extrusion tooling for the global market, has opened an in-house rheology laboratory, making it the only extrusion tooling ma- nufacturer in the industry with such a ca- pability. Seeking to obtain better results and minimize the time it takes between In-House Rheology Lab launched cludes a Hybrid Rotational Rheometer, a Differential Scanning Calorimeter, and a Thermal Conductivity Meter. Right picture: TA Instruments Discovery HR-2 Hybrid Rotational Rheometer Left picture: TA Instruments DSC-25 Differential Scanning Calorimeter Main features and improvements: The hot/cold mixing combination got as beating heart a five stages high intensity mixing tool in stainless steel with tungs- ten carbide coating for wear protection. It also has inclined blades to ensure the best mixing vortex: 20° of inclination for the upper stage and 30° the lower stage. Both Heating Mixer and Cooler are with all surfaces in contact with the process material mirror polished in order to re- duce cleaning and maintenance times and to avoid residues at the end of mix- ing cycle in order to eliminate any conta- mination issues when changing formula- tion and process conditions batch to batch. Giving the mixing plant the neces- sary versatility, allowing our customer to develop new products and explore the use of new raw materials. Promixon improved also the water circuit in the cooling jacket, optimizing the flow of coolant water in the double jacket with a coil real and reducing by 30% the cooling times. Finally, the software has been customized to the specific request of the customer with a S.C.A.D.A. (Su- pervisory Control And data Acquisition) solution interfaced with the customer ERP system for data exchange, statistics, traceability of production lots, cost eva- luation and much more.
