The basic versions of the Mflow extrusion plastometers are used to determine the melt mass flow rate (MFR). Use of the displacement transucer expands their function to include determination of melt volume flow rate (MVR) and a unique automatic adaptive parameter configuration. Typical uses are in quality control and goods inwards.

• Zwick's unique automatic adaptive parameter configuration is a 'world's first' system which automatically sets test parameters in accordance with material being tested to minimize measuring errors.
• Special heating elements ensure precise temperature levels in the extrusion barrel.
• Operator comfort and convenience thanks to the pneumatic weight-lifting system - weights can be raised and lowered automatically.
• Automatic bubble detection identifies air bubbles in the plastic melted mass and immediately excludes them from MVR calculation.
• Precision displacement transducer ensures exact measurement of piston travel when determining MVR. The contact point is very close to the piston, minimizing possible angle errors from the outset.
• The Mflow extrusion plastometer can either be used as a stand-alone unit or operated via testXpert^® II software as required.
• Mflow extrusion plastometers come with a generous standard package backed by a comprehensive range of accessories.
• The Mflow weight selector option combines the advantages of pneumatic weight raising with the convenience of simple, safe and reliable changing of test weights, ensuring secure storage and an operator-friendly test sequence.
