Zw/ck / Roell Materials Testing Product Information Cflow Extrusion Plastometer Applicational range The Cflow is a compact instrument that allows rapid determination of the Melt mass flow rate of plastics. It is specifically designed for the processors of plastics that are less subject to extrusion tests and which do not The temperature control of the heating elements, the heating chamber and the extrusion barrel are perfectly matched to each other. The temperature is generated where it is needed. That ensures an excellent distribution of temperature across the full height of the barrel from the outset. Rapid device control is facilitated by the test granulate contained in the scope of delivery. Addition control options are available for the temperature in the extrusion barrel, for the diameter of orifices and barrels with plug An automatic or manual extrudate cutter, a separating door and a die plug are optionally available for the • The extrusion behavior of plastics is tested safely and quickly according to Method A • You hold the test weight in the pre-heating position with the optionally available spacer • Extensive accessories, such as the automatic or manual extrudate cutter, are also available All data at ambient temperature.

Zw/ck / Roell Materials Testing Product Information Cflow Extrusion Plastometer Protective shields For catching individual extrudates. Description Item number Protective shield, for automatically operated extrudate cutter 001379 Protective shield, for manually operated extrudate cutter 004996 Extrudate cutters and orifice plug For short cutting intervals the automatic extrudate cutter would be the right solution to get a precisely timed cut. The orifice plug prevents the early flow of the plastic material when testing with high flow rates (> 10 cm3 / 10 min at a load of 0.375 kg). If the...
