Laboratory Compounder with Downstream Equipment

The twin-screw kneader with co-rotating screws is suitable for continuous melting, mixing, homogenizing, alloying and discharging of plastic materials.
Various downstream equipment is available with which granules, foils and polymer strings can be produced.
