Melt flow tests are a simple method of characterizing the flow properties of a plastic melted mass. This test method is widely used, especially in quality assurance and goods inwards testing. The demands placed on the extrusion plastometer vary according to which processing stage in the plastics industry is involved.

Aflow was developed especially for laboratories with high testing volumes, as reflected in its robust design and convenient operation. It supports all established worldwide standards, including ISO 1133 and ASTM D1238. Aflow can be used to determine melt mass flow rate (MFR) and melt volume flow rate (MVR) to Methods A, B, C and D.

The basic version of the Mflow extrusion plastometers can be used to determine the melt mass flow rate (MFR). The plastometer features modular design. Using the piston transducer expands Mflow's capabilities to include determination of melt volume flow rate (MVR) plus automatic adaptive parameter configuration. Typical uses are in quality assurance and goods inwards checks.

The compact Cflow extrusion plastometers are designed as a stand-alone instrument for rapid monitoring of melt mass flow rate. They are primarily used for goods inwards checks at plastics processing plants where extrusion tests are performed on an irregular basis.
