Cflow - the Compact One

The compact Cflow extrusion plastometers were designed as stand-alone instruments for rapid inspection of the melt mass flow rates (MFR). They are mainly used for incoming goods inspections by plastics processing companies, where extrusion tests are performed sporadically.

Advantages

  • Temperature control of the heating elements, heating chamber and barrel are all perfectly co-ordinated. The temperature is generated at the location where it is utilized, ensuring excellent temperature distribution over the whole barrel height from the outset.
  • Simplified cleaning, with rapid expulsion of residual specimen material.
    - The die plug is located on the underside of the extrusion barrel. Removing the die plug frees the die to move downwards, allowing it to be removed easily.
    - Expelling the die plus residual material after the test is similarly fast and easy. The barrel is now accessible throughout., simplifying cleaning.
  • The optionally available test weight support allows you to retain the test weight in the pre-heating position.
  • Comprehensive accessory range including automatic or manual extrudate cutter, separating pane and die plug is optionally available.

Applications

Cflow is a compact instrument for rapid checking of the melt mass flow rate of plastics as per Method A.

It is primarily designed for plastics processors with a less frequent need for extrusion tests and no requirement for connection to a PC.

Cflow is intended for MFR tests to Method A. Tests can be performed in accordance with the following standards:

  • Method A as per ISO 1133, ASTM D1238, ASTM D3364, JIS K 7210.

The instrument can quickly be checked using the test granulate included in delivery. It is also possible to check the temperature in the extrusion barrel and the diameter of dies and barrels using plug gauges.

Cleaning

Simplified cleaning, with rapid expulsion of residual specimen material

The die plug is located on the underside of the extrusion barrel. Removing the die plug frees the die to move downwards, allowing it to be removed easily. Expelling the die plus residual material after the test is similarly quick and easy. Cleaning is simplified because the barrel is now accessible throughout. The Pneumatic Weight-lifting with Cleaning Function option also enables simple, convenient cleaning of the extrusion barrel at the touch of a button.

Technical Overview

The Cflow is designed for MFR tests to Method A. Tests can be performed to the following standards: Method A to ISO 1133, ASTM D1238, ASTM D3364, JIS K 7210.
