Melt Flow Index Tester for HDPE Blow Moulding Grades

Extrusion plastometer that measures melt flow rate of HDPE resin at 190 deg C and 2.16 or 5 kg load. Used by bottle makers and resin suppliers to verify blow moulding grades before use in extrusion blow machines.

Specification

Granules are melted in a heated barrel and forced through a standard die by a dead weight, and the extrudate is cut and weighed over timed intervals. The result is reported as g/10 min. It helps confirm that incoming HDPE lots suit the bottle process window.
