Advanced Melt Flow Testing for Plastics and Polymer Materials
The Ray-Ran MFR300 Microprocessor Melt Flow Indexer is an advanced, fully featured melt flow testing system designed to provide fast, accurate and repeatable measurement of plastic and polymer material properties. Combining intuitive touchscreen operation, intelligent software and precision temperature control, the MFR300 is ideal for quality control, quality assurance and research laboratories requiring reliable material characterisation.
Manufactured by Ray-Ran, a globally recognised specialist in plastics testing equipment with decades of experience in melt flow analysis, the MFR300 delivers the accuracy and flexibility required by industries including plastics manufacturing, packaging, automotive, aerospace, medical devices and polymer research.
Comprehensive Melt Flow Testing Capability
The MFR300 provides a complete analysis of polymer flow behaviour, measuring:
- Melt Flow Rate (MFR)
- Melt Volume Rate (MVR)
- Density at Test Temperature
- Shear Stress
- Shear Rate
- Viscosity
- Apparent Intrinsic Viscosity (PET)
- Flow Rate Ratio (FRR)
This broad testing capability allows manufacturers to evaluate material consistency, optimise processing conditions, reduce production defects and improve product quality across extrusion and moulding applications.
Precision Melt Flow Analysis
The MFR300 incorporates advanced measurement technology, including an optical rotary encoder for highly accurate piston displacement measurement when performing Method B and Method C testing.
An integrated automatic cutting system provides consistent and repeatable sample cuts for Method A testing, Method B testing (where required), and density measurement at test temperature. This ensures reliable data collection, improved traceability and confident quality control decisions.
Intuitive Touchscreen Operation
Designed for simplicity and efficiency, the MFR300 features a clear 4.3-inch touchscreen display with intuitive icon-based menus and guided test instructions.
Users can quickly select and perform testing methods including:
- Method A
- Method B
- Method C
- Method D
- Density at test temperature
The user-friendly interface reduces operator training time while minimising the risk of setup errors in busy laboratory and production environments.
Advanced Software and Data Management
The MFR300 is supplied with Ray-Ran Techni-Test™ software, providing advanced results management and reporting capabilities.
With built-in Wi-Fi connectivity, USB and Ethernet communication, test results can be easily transferred, analysed and stored.
Techni-Test™ enables users to:
- Display results in graphical and tabular formats
- Generate and print test reports
- Export CSV files for Microsoft Excel analysis
- Recall previous test results for comparison
- Monitor material trends and process performance
Multi Data Point (Multi-Slice) Testing
A key feature of the MFR300 is its advanced multi-slice testing capability. Instead of relying solely on physical sample cuts, the system captures multiple measurement points throughout the extrusion process.
This provides:
- Improved test accuracy
- Faster testing procedures
- Identification and removal of abnormal data points
- Automatic recalculation of final results
- Greater confidence in material evaluation
Accurate Temperature Control
The MFR300 uses an innovative dual-zone heating system to maintain exceptional temperature stability and comply with international melt flow testing standards.
Temperature accuracy is maintained to ±0.10°C, ensuring repeatable results across all testing conditions.
An integrated eco mode reduces power consumption during idle periods, helping laboratories lower operating costs while supporting sustainability initiatives.
Robust Design and Flexible Configuration
The MFR300 is supplied with high-quality testing components designed for long-term reliability, including:
- Hardened steel replaceable cylinder liner
- Tungsten carbide test die
- Piston assembly
- 2.16 kg standard test weight
- Automatic cutting blade
- Cleaning tools and accessories
For challenging materials such as PVC and fluoropolymers, optional Hastelloy components are available to improve corrosion resistance and minimise maintenance requirements.
Standards Compliance
The Ray-Ran MFR300 is pre-programmed for testing in accordance with major international standards, including:
- ASTM D1238
- ASTM D3364
- ISO 1133
- DIN 53735
The system supports Methods A, B, C and D, including Flow Rate Ratio (FRR) testing.
