Germany-based Gneuss Kunststofftechnik GmbH — a manufacturer of filtration, measurement and
processing technologies for plastic melts — is celebrating its 25th anniversary.
Gneuss began operating in 1983 with the idea of inventing a new type of screen changer, using
rotary melt filtration technology. To date, there are more than 4,000 melt filtration systems in
operation, for raw materials, film and sheet production; compounding; and other polymer processing
applications; as well as recycling of contaminated polymers.
The latest technological development from Gneuss is the MRS extruder, a special multiple
screw extruder, which can be used to process polyethylene terephthalate (PET) without predrying.
The MRS system features a rotating single-screw drum with eight to 10 integrated satellite screws,
providing a large devolatilising capacity; a large melt surface area in the degassing zone; and a
20-millibar vacuum. The MRS35 extruder can be used in the production of chalk-filled low-density
