Applications:

　　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 melt flow index tester / extrusion plastometer vary according to which processing stage in the plastics industry is involved.

Product Information:

　　Aflow extrusion plastometer

　　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.

　　Advantages of Aflow testing machines

　　· optimized, operator-independent test sequence

　　· Automatic Parameter Control (APC) during test

　　· steplessly adjustable test loads up to 50kg

　　· rapid residual material extrusion after test under up to 80kg force

　　· uniform pre-compacting and labor-saving cleaning at the push of a button

　　· time-saving multi-stage tests

　　· intelligent testXpert II connection via USB

　　· space-saving multiple instrument operation with up to 6 Aflow/Mflow instruments on one PC

　　· precise temperature control to ISO/DIS 1133-2

　　· convenient stand-alone operation

　　Cflow extrusion plastometers

　　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.

　　Features of Cflow extrusion plastometers

　　· Temperature control of the heating elements, heating chamber and barrel are all perfectly co-ordinated. The temperature is generated where it is applied, ensuring excellent temperature distribution over the whole barrel height from the outset.

　　· Ergonomic design allows swift, effortless operation

　　· Cflow extrusion plastometers feature a generous standard package backed by a comprehensive range of accessories.

　　Mflow extrusion plastometers

　　The basic version of the Mflow extrusion plastometers can be used to determine the melt mass flow rate (MFR). The plastometer features modular design and can be expanded by using the piston transducer to enable determination of melt volume flow rate (MVR) and for automatic adaptive parameter configuration. Typical uses are in quality assurance and goods inwards checks.

　　Advantages of Mflow extrusion plastometers

　　· Zwick's automatic adaptive parameter configuration automatically sets test parameters in accordance with the material being tested to minimize measuring errors automatically.

　　· Special heating elements ensure very high temperature accuracy in the extrusion barrel.

　　· Pneumatic weight-lifting system ensures operator comfort and convenience - weights can be raised and lowered effortlessly.

　　· Automatic bubble detection identifies air bubbles in the plastic melted mass and immediately excludes them from the MVR calculation.

　　· Precision piston-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.

　　· Mflow extrusion plastometers can 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.
