Melt Flow Index Tester for Injection Molding Grades

Extrusion plastometer that measures melt mass-flow rate and melt volume-flow rate of thermoplastic molding compounds. Used by injection molders and resin QC labs to verify batch consistency before production runs.

Specification

This melt flow index tester gives molders a quick check of incoming pellets and regrind. A PID-controlled barrel holds temperature within a narrow band while a calibrated weight pushes the melt through a standard die. Results are used to set injection pressure and cycle time.

Features

• PID controlled barrel up to 400 deg C
• Interchangeable dead weights from 0.325 to 21.6 kg
• Automatic cut-off timer with digital display
• Stainless steel barrel with hardened die
• Suitable for PP, PE, PS, ABS, PA and PC
