Datasheet: Conical Twin Screw Extruder

The co-rotating and counter-rotating conical twin screw extruder is ideally suited for quality control, product development and research applications.

All the screws allow a uniform forward flow regardless to the degree of flight filling, feeding uniformity, polymer flow characteristics, or back pressure.

The co-rotating channel allows material to flow from one screw to the other in a constant wiping motion. In contrast, the counter rotating chamber produces a milling action between the screws similar to a calendering process.

Materials can be metered with precision feed units to exact specifications, while the barrel of the extruder is designed to allow additional materials such as liquid monomers, colors or plasticizers to be added at various stages of the testing process.
