Melt Flow Indexer

Melt Flow Indexer | MFI452A FunctionThis type of melt flow indexer is a high precise melt testing instrument for the measurement of melt flow rate (MFR)/(MI) or melt volume rate (MVR) in quality control and research applications. The testing result can distinguish the viscous flow performance of thermoplastic material by the model MFI452 showing its advantage in the following industries: factories, products quality testing station, scientific and research institutes, and concerned industries.
Standards
ISO1133, ASTM D1238, ASTM D3364, BS2782, DIN53735, JIS K7210
FeaturesFriendly operation interface, switching display in Chinese and English, reducing test difficulty.Free switching between the mass method and the volume method, the test interface is intuitive, greatly reducing the difficulty of operation.Material barrel and piston rod and other key parts are made of high temperature resistant, low expansion coefficient alloy material, and special surface heat treatment, in the case of high temperature deformation is not easy, and high hardness, not easy to wear, can be used for a long time.Optical high precision displacement measuring device, small additional force measurement, ensure accurate data.Equipped with an automatic cutting device driven by a miniature motor, the cutting time can be set, and the rotating electric machine can be cut at a fixed time according to the set cutting time, with accurate time control and small error. The cutting device can also be manually driven. Simple and convenient operation.Equipped with microcomputer controller, it can control the whole process of the test process, data processing, data printing, etc., and can print out the test results through the equipped microprinter.Equipped with special weight box, groove one by one to avoid the loss of accessories.StructureThe main body of the equipment is made of 1.5mm thick high-quality alloy, equipped with 7-inch color display. The operation interface can be switched between Chinese and English, and the friendly interface can display the test parameters in real time.Good temperature uniformity: and the furnace barrel is one-body red copper casting, which can effectively ensure the temperature stability and uniformity of the test area.The displacement measurement is simple with good reliability and high measurement accuracy.Equipped with different cleaning solutions according to different operating conditions. The cleaning process is simple, rapid and thorough, which can effectively avoid the influence of incomplete cleaning on test results.The cutting motor has a high repeatability. At the same time, the self-locking function is set on the program to avoid the influence of external interference on the test results.Newly equipped with a sample tray, which can be rotated to avoid the adhesion of high-temperature samples and ensure the accuracy of test results to the greatest extent.The base structure is wide and the equipment is stable.Equipped with a micro printer, the test results can be archived for easy traceability.SpecificationsModelMFI452ATemperature rangeºC100~450Temperature accuracyºC±0.5Temperature variation in 4 hoursºC≤0.5Temperature variation with distance at between
