Single Screw Extruder

Intended Use

Product development, inspection, quality control during production and small-scale production of hoses, tubes, films, and other profiles


Built to me rigid manufacturing standards

  • Sixteen standard models include L/D ratios of 10:1, 15:1, 20:1, 25:1, and 30:1.
  • Different models provide alternate methods of heating and cooling.
  • Temperature regulation on each is performed by a corresponding Brabender Control Console or Circulator System.

Screw sizes .5", .75" and 1.25" available - Various L/D ratios available

C.W. Brabender Laboratory Extruders are built to meet rigid manufacturing standards. They must provide close test reproducibility in order to act as measuring heads to the Plasti-Corder torque rheometer, a precision instrument. Their output depends on testing variables such as, melt temperature, extrusion material, screw and die design, rpm, pressure and feeding.

  • Extrusion Profiles
  • Small Scale Production Processing


The 416 stainless steel, honed and nitrided barrels are manufactured in various L/D ratios. The extruders are equipped with two ports near the screw tip for either a transducer or a stock temperature thermocouple, and a rupture safety plug. Barrels can be supplied with grooves for improved shearing and positive transport of material in the extruder. Other designs and alloys can be provided for special applications.
