XNR-400A Melt Flow Index Tester

Product Introduction
The XNR-400A Melt Flow Index Tester is designed to measure the melt mass-flow rate (MFR) of thermoplastic materials under specified temperature and load conditions. It features intelligent temperature control, a short temperature stabilization cycle, and minimal temperature overshoot to support reliable and repeatable testing.
With both manual and timed cutting modes, the XNR-400A allows users to set cutting intervals and cutting durations according to their testing requirements. Its wide temperature range and straightforward operation make it suitable for plastic manufacturers, quality inspection laboratories, research institutions, and universities.

Performance Features
•   Wide measurement range: MFR measurement from 0.1 to 400.00 g/10 min.
•   Precise temperature control: Temperature control accuracy of ±0.2°C.
•   Intelligent temperature regulation: AI-based instrument control helps reduce temperature overshoot and improve stability.
• Flexible cutting modes: Supports both manual and time-controlled sample cutting.
•    Adjustable timing: Configurable timing ranges for different test procedures.
•    Standardized test components: Precision barrel and tungsten carbide die.
•   Compact laboratory design: Suitable for routine plastic material testing and teaching applications.

Working Principle
The melt flow index tester heats a thermoplastic sample inside a barrel to a specified temperature. Under the prescribed load, the molten material flows through a standard die. The extrudate is collected by manual or timed cutting, and its mass is measured over a defined period to determine the melt mass-flow rate, expressed in g/10 min.
The XNR-400A uses an intelligent temperature-control system to maintain the test temperature and a timing control system to coordinate cutting intervals. Test conditions, including temperature and load, must be selected according to the applicable material test method.
