MELT FLOW INDEX TESTER 
MFI tester is designed to calculate accurate rate of extrusion of molten resin through an orifice of specified diameter and length under prescribed condition of temperature and pressure. It consists of electrically heated barrel where the linear temperature is kept constant at the present temperature by electronic control circuit. Normally temperature range is upto 300° c. The equipment works on single phase 230 volt power supply with wattage of 0.75KW. The temperature is precisely controlled within 0.1c. by PID temperature controller
