Compounding extruder meets stringent clean room requirements

Published: 1-Apr-2009

Tampere-based ConMed Linvatec Biomaterials is using a KraussMaffei Berstorff Ultra Glide laboratory extruder to produce biodegradable compounds based on lactic acid.

For the production of implants used in the human body cleanroom conditions are essential. The KraussMaffei Berstorff extruder was designed in strict compliance with the Good Automated Manufacturing Practice (GAMP). The leading Finnish manufacturer of medical products opted for the extruder from Hanover as it meets the most stringent requirements of this special field of industry.

Implants based on polylactide plastics fix the bones in position just like conventional implants offering at the same time the decisive advantage that they need not be removed in a second surgery after the fracture has healed. Experience has proven that the KraussMaffei Berstorff extruder is perfectly suited for producing PLA compounds.

The Ultra Torque model in the ZE series is characterised by high drive power for screw speeds of up to 1,200 rpm and outstanding material output rates. At the same time, the machine ensures rapid and careful processing, which is of particular importance with these demanding compounds.

With the special Ultra Glide version, the extruder screw is extracted within a minute from the processing section, which facilitates access to the screw and substantially reduces the cleaning time in the case of a recipe change.
