Built to meet rigid manufacturing standards
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.
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.

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.
