Applications
Melt Flow Index Tester is used to test the flowability of thermoplastic polymer under high temperature, such as polyethylene, polypropylene, pom, ABS resin, polycarbonate, nylon fluorine and other plastic polymers. The automatic temperature control methods of the machine three kinds of blanking ways, manual, timing and automatic control according to operation method, which can realize melt-mass flow rate (MFR) and melt-volume flow rate (MVR) two test methods.
Advanced Features for Precise TestingEquipped with a digital control system, microprocessor-based technology, and a LED digital display, the Melt Flow Index Tester ensures pinpoint accuracy with 0.5% reading. Integrated components like a corrosion-resistant stainless steel die and a hard chrome plated piston increase durability, while features such as an automatic cut-off device and overload protection support safe and consistent operation.
Flexible and User-Friendly OperationDesigned for a range of operational conditions (10C to 40C and up to 80% RH), the tester incorporates a passive cooling system and drawer-type sample collection for convenient testing. A standard set of 8 weights and digital single-point calibration allow for flexible and easy adjustments, making it suitable for various thermoplastic materials. The automatic motorized cut-off streamlines workflow, ensuring repeatable results.
FAQs of Melt Flow Index Tester:
Q: How does the Melt Flow Index Tester ensure accurate measurement of thermoplastic materials?
A: The tester utilizes a high-resolution temperature control (up to 400C, 0.1C resolution) and a microprocessor-based system to provide precise and repeatable melt flow readings. The digital single-point calibration and LED digital display further support measurement reliability.
Q: What is the process for operating the Melt Flow Index Tester?
A: Operation involves loading the sample into the stainless steel barrel, setting the required test parameters on the digital controller, and initiating the test. The integrated barrel heater and automatic cut-off mechanism simplify and automate most steps. Sample collection is made easy with a drawer-type system.
Q: When should I use the Melt Flow Index Tester in plastic processing workflows?
A: This tester is most beneficial during quality control and research phases, whenever you need to measure the melt flow characteristics of thermoplastics to ensure product consistency and performance standards are met.
Q: Where is the Melt Flow Index Tester typically used?
A: It is widely employed in laboratories, manufacturing units, research and development facilities, and quality assurance departments within the polymer industry. Its design is also suitable for environments with ambient conditions between 10C and 40C.
Q: What advantages does the motorized automatic cut-off mechanism offer?
A: The motorized automatic cut-off ensures that each measurement is stopped precisely according to preset parameters, reducing operator error and ensuring consistent, accurate results for every test.
Q: How do the overload protection and alarm system improve usage safety?
A: These features monitor the devices operating status, preventing damage from excessive weight or temperature, and alert the user immediately if unsafe conditions are detected, helping maintain a secure testing environment.
