Melt flow index tester measuring MFR and MVR of thermoplastics such as PE, PP, ABS and PC, with PLC control. Request a quote.
Overview
This tester is designed per GB/T 3682 "Determination of the Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR) of Thermoplastics" to measure the flowability of thermoplastics such as PE, PP, ABS and PC at elevated temperature. PLC-controlled with a color touchscreen, it automatically controls temperature and supports both the mass method (MFR, g/10min) and the volume method (MVR, cm/10min). The specimen is loaded into a vertical barrel, melted, and extruded through a tungsten-carbide die under a standard weight load; cutting is available in manual, timer-controlled or automatic modes. A built-in micro printer outputs test reports on site.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Built-in thermal printer for immediate test record output
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Melt Flow Indexer (MFR/MVR Tester) comply with?
A1: The Melt Flow Indexer (MFR/MVR Tester) is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Melt Flow Indexer (MFR/MVR Tester) be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
