Screw-type rubber extruders (GS) manufactured by TROESTER and used by the leading rubber processing companies in Europe and abroad have, for over a century, been recognised as setting the benchmarks in output and production quality.Depending on the application, TROESTER can supply the right GS extruder: cold feed (GS/k), hot-feed (GS/w) and vertical (GSV) Extruders. The GS series also includes vacuum (GS Vak) and pin-type extruders (QSM).

A QSM (cross-flow mixing) extruder is of a similar design to a cold-feed conventional extruder. The marked difference lies in the combination of screw and barrel which depending on the application, is equipped with up to 12 rows of pins.
