Extrusion International 3-2022

48 Extrusion International 3/2022 Extrusion Technology T hermHex Waben installed their first MEAF ex- truder in 2015, the 75-H34. Impressing with its re- sults and durability, in November 2021 the company invested in a second MEAF extruder to work along- side their existing one, another 75-75 mm and a 34:1 L/D-ratio screw. Fitted with special features to connect the two ex- truders and by combining both production streams ThermHex Waben was able to double capacity and with most efficient energy usage. They have in- creased their theoretical capacity in production honeycomb cores from 500 kg to 1000 kg per hour, which is equivalent to 3,000 tonnes per year in two- shift production. MEAF extruders offer a significant sheet extrusion line energy efficiency over its competition, in a di- Reduced Energy Consumption in Honeycomb Production by up to 65 Percent and Double Capacity EconCore, the world leader in technologies for economic honeycomb sandwich production and ThermHex Waben, producer of polypropylene honeycomb cores for lightweight sandwich panels and composites, have doubled capacity in the production of honeycomb cores, with reduced energy consumption by up to 65% compared to alternative solutions. The two companies recently installed MEAF H-Series extruders within their state-of-the-art production facilities.
