This is a device for measuring the indices MFR (Melt Mass Flow Rate, g/10 min) and MVR (Melt Volume Flow Rate, cm3/10 min), which represent the flowability of thermoplastic resins during melting. There are two testing methods: Method A (mass measurement method) and Method B (movement distance measurement method). With a modular design, you can freely add your preferred options such as the flow rate device for Method B measurement (piston movement distance measurement encoder), weight lifting device, cutting device, etc. By adopting a mechanism that allows for easy removal of the orifice die from the lower part of the furnace body, the workability and safety during cleaning have been improved. The load of residual resin extrusion has also been reduced. Testing conditions (preheating time, testing temperature, testing load, etc.) can be registered via a liquid crystal touch panel. Test results can be output to a computer* (a dedicated software option is required). Measurement data can be output in real-time to the dedicated software*. Trend graphs can be displayed, allowing for a visual understanding of the trends in MVR/MFR measurement values. (Optional, Method B only) An automatic cutting device (with a sliding mechanism) can be used in conjunction with a flow prevention clamp.

【Features】 ■ A load range of 0.325kg to 21.6kg is pre-installed in the device. By automatically selecting the weight, the operator's burden is reduced, and the safety of the operation is improved. ■ Up to three-step load increments and decrements (multi-weight measurement) can be performed automatically in a single test. This allows for the determination of the flow rate ratio (FRR), which is commonly used as an indicator of how the rheological properties of thermoplastic materials are affected by the molecular weight distribution. (ASTM D1238 Method D) ■ It can also be used as a standard single-weight measurement melt indexer (MFR/MVR measurement device, MFR meter, MI meter, melt flow rate testing machine).

● Fully automated from sample input to cleaning. Contributes to labor-saving, efficiency improvement, and reproducibility enhancement in measurement tasks. ● Continuous testing of 10 sample cups (optional 40 cups) is possible. ● Compact and space-saving desktop model (height 1060mm). ● A wide range of options available (automatic measurement by method A, dry air drying unit, load change mechanism, etc.).

When filling the sample into the melt indexer, depending on the shape and properties of the sample, it may not be possible to fill it within one minute (JIS K 7210). This device heats and compresses the sample at a temperature lower than its melting point within the furnace body, molding it into a stick shape. By molding it into a stick shape, filling the sample into the melt indexer becomes easier. Since filling can be performed under constant conditions, the test conditions are standardized, allowing for the acquisition of accurate data. Additionally, it is possible to reduce the effects of hydrolysis.

- Equipped with a measurement automation unit, it automatically performs a series of operations from the start of measurement after sample input to the end of measurement. - It automatically handles the load of test weights and the discharge of residual samples, contributing to reducing the operator's workload, improving safety, and shortening work time. - By arbitrarily setting the preheating conditions (preheating time, piston holding position, and holding time), it is possible to keep the actual preheating time constant until the start of measurement, enabling stable measurements. - With the furnace cleaning unit, the cleaning of the furnace cylinder can be done simply by setting a gauze.
