Lab scale Co-kneader
The barrel and screw could also be segmented according to application. The optimization of screw configuration is also needed. Too much kneading elements rapidly increase stock temperature; on the other side too less kneading element is not enough for high quality kneading. The co-kneader use many types of screw elements; basically fast and slow conveying, short kneading and kneading elements for restriction ring. Additionally elements with increased core diameter, kneading element with backward flowing characteristic and others are also usable. The restriction ring is special bore element with lower core diameter which increase melt pressure for high quality mixing. The diameter of restriction ring also need to be optimized for reducing shear rate and stock temperature.

Unique Working Principle
The optimization of production technology is the main goal of all companies. The main reason of this process is increasing production quality, capacity and decreasing the cost. In same cases of lab compounding, there is some limitation for temperature sensitive and shearing sensitive application due to extremely high shear rate of co-rotating Twin Screw Extruder. In such case, the priority shall be given to the Co-kneader. Co-kneader has low intensive mixing properties but without any pressure and temperature peak compared to co-rotating twin screw extruder. Also Co-kneader has stable shear rate independent on screw size. This is very useful for up scaling from laboratory data.
