Semi-Automatic Melt Indexer - "Semi-Auto Melt Indexer 4A"
Catalog No. 521, Model 4A
Semi-automated melt indexer (MFR/MVR measurement device, melt flow tester) for load elevation, residual resin extrusion, and furnace cylinder cleaning, etc.
- 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. - The load of the test weights and the discharge of residual samples are performed automatically, contributing to reduced operator workload, improved safety, and shortened working time. - By arbitrarily setting the preheating conditions (preheating time, piston holding position, and holding time), the actual preheating time until measurement starts can be kept constant, enabling stable measurements. - With the furnace cleaning unit, the cleaning of the furnace cylinder can be done simply by setting a gauze.

Applications/Examples of results
This is a testing machine (Melt Indexer, MI meter, MFR tester, Melt Flow Index tester) that measures the indices MFR (Melt Mass Flow Rate) and MVR (Melt Volume Flow Rate), which represent the flowability of thermoplastic resin during melting. It is a semi-automatic model that automates and powers functions such as test load elevation and descent, residual resin extrusion, and cleaning of the furnace cylinder.
