German biocompounder Tecnaro GmbH has doubled its production capacity, thanks to a new KraussMaffei Berstorff compounding line.
In 21 June statement, KraussMaffei Berstorff said the bioplastics specialist will use the new twin-screw extruder to meet the increasing demand for tailored alternative plastics compounds, cost-effectively and in large volumes.
Based in Ilsfeld-Auenstein, Germany, Tecnaro specialises in technologies for the industrial use of renewable raw materials in plastics processing.
The company offers lignin-based compounds, known as Arboform, for loudspeakers, musical instruments, toys, design objects or urns. It also supplies the bio-degradable raw materials of the Arboblend series for packaging, office supplies, household items, film and sheets.
A third Tecnaro product line is based on filled compounds made from renewable raw materials.
Tecnaro produces these biocompounds on twin-screw extruders.
"We started with second-hand machines, one of which was originally delivered by KraussMaffei Berstorff. This is one of the reasons why we opted again for a compounding line from Hannover," said Jürgen Pfitzer, chief executive officer of Tecnaro GmbH.
The recently installed new line is a ZE Basic 62 twin-screw extruder for a maximum output rate of 800 kg/h.
"The possible scale-up of our formulations for the production of larger quantities of specific compounds on the new extruder is of decisive importance to us," added Jürgen Pfitzer.
The twin-screw extruders of the ZE Basic series are versatile and suitable for about 80% of all plasticising, filling and reinforcing applications without requiring any major equipment modification, according to KM Berstorff.
The series comprises a total of four extruder sizes with diameters ranging between 42 and 77 mm and output rates of up to three tonnes/hour.
