Qinsun Melt Flow Index Tester & MFI tester User Guide

1. Product Overview The Melt Flow Index Tester is designed in accordance with ISO 1133 and ASTM D1238 for the determination of melt mass-flow rate (MFR) of thermoplastic materials. The instrument measures melt flow rate using an automatic sampling and weighing method, and calculates the final melt flow index based on standard formulas. Test results are displayed on the LCD screen and can be printed via the built-in micro-printer. The tester provides stable temperature control, accurate load application, and reliable measurement performance. It is suitable for testing engineering plastics and general-purpose plastics with relatively low melting temperatures. 2. Application The instrument is used for melt flow rate testing of thermoplastic materials, including but not limited to: Polyethylene (PE) Polypropylene (PP) Polyacetal (POM) Polystyrene (PS) ABS resin Polycarbonate (PC) Nylon (PA) Fluoroplastics 3. Standards The Melt Flow Index Tester complies with the following standards: ISO 1133 — Plastics — Determination of the Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR) ASTM D1238 — Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer 4. Parameters Parameter Specification Test Method Melt Mass-Flow Rate (MFR) Index Range 0.1–400.00 g/10 min Temperature Range Ambient to 400 °C Temperature Accuracy ±0.2 °C Temperature Resolution 0.1 °C Timing Accuracy 1 s Test Load Relative Error ≤ ±0.5 % Display LCD Printer Built-in micro printer Scraper Mode Automatic / Manual Power Supply 220 V ±10 %, 50 Hz Power Consumption 0.45 kW Instrument Dimensions 510 × 370 × 600 mm Host Weight 25 kg Standard Weights Total Mass 21.6 kg 5. Features (1) PLC-controlled system with LCD display for real-time indication of temperature, test time, and sampling cycles. (2) Automatic melt mass-flow rate measurement with high measurement accuracy and good data repeatability. (3) Eight standard test loads available to meet different material testing requirements. (4) Built-in micro-printer allows test reports to be printed at any time for data archiving. (5) Automatic or manual cutting modes selectable according to test requirements. (6) Stable temperature control and uniform heating ensure reliable test results. 6. Test Procedures (1) Install the die, piston, and barrel according to the test standard and select the appropriate test load. (2) Set the test temperature and allow the barrel to reach thermal equilibrium. (3) Charge the test material into the barrel and install the piston and selected weights. (4) Start the test and perform automatic or time-controlled cutting as configured. (5) The instrument automatically measures and calculates the melt mass-flow rate. (6) Test results are displayed on the LCD screen and can be printed if required.
