Why using a Ram Extruder instead of continuous working screw extruder?
A Ram Extruder uses the platform of a capillary rheometer, a well proven testing instrument in the polymer industry. High precision temperature control guaranties stable condition within the reservoir.
The heating process in the reservoir is very gentle, compared to undefined mixing in a continuous extruder which might lead to unwanted shear heating. The linear speed driven ram guaranties a constant and stable diameter of the extrudate, which can not be reached with the pulsating flow in a screw driven extruder.
The batch process of a ram extruder guaranties minimum off spec material and product waste. High cost products, quantities can be processed with less than 100 ml per extrusion cycle
Advantages of the discrete, discontinuous RAM extrusion compared to the conventional screw extrusion in the clean room production.
