TRICO-Ram

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.

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

 

Highlights
  • Three independently speed controlled pistons extrude products within a speed range from 0.00004 - 40 mm/sec.
  • 200 ml reservoirs in all three barrels provide sample volume for batch extrusion processes
  • Due to independent piston drive control, different volume rates in all three barrels can be maintained
  • Extrusion process is monitored and controlled by three extrusion pressure transducers, three product temperature sensors and applied triple piston force control up 40 kN
  • Temperature control between 30°C – 250°C
  • Design approved to clean room condition according to class A
