MFI Melt Flow index in production Issues such as unstable injection pressure, workpiece warpage, or inconsistent plastic quality between batches are often caused by variations in. Melt Flow Rate No.120-FWP (Melt Flow Index Tester) is a manual-operation instrument designed for determining MFR/MVR values. It utilizes an encoder-based displacement measurement system with a resolution of 0.0018 millimeters and supports data analysis via graphical plots.
Accurately measure melt Flow index: Determine the MFR (Melt Mass-Flow Rate) and MVR (Melt Volume-Flow Rate) to evaluate the quality and melting behavior of plastic pellets prior to the manufacturing process.
Easy to use and highly accurate: Designed for manual operation, the system ensures stable temperature control within the melting barrel and supports testing according to both Procedure A and Procedure B.
Fully compliant with international standards: Covers test methods in accordance with ISO 1133, ASTM D1238, JIS K7210, and other standards within the plastics industry.
Easily adjust the applied load and test conditions: Standard test weights and accessories for specimen cutting are available, selectable based on the type of plastic being tested.

Q: What does the MFR (Melt Mass-Flow Rate) value obtained from a testing machine indicate?
A: The MFR (Melt Flow Rate) value indicates how easily or difficultly a plastic material flows when heated. A high MFR value means the plastic flows easily, making it simpler to process via injection molding, though it may result in lower mechanical strength. Conversely, a low MFR value indicates that the plastic is more resistant to flow—often due to longer molecular chains—which necessitates specific adjustments to the temperature and pressure settings of the injection molding machine.
Q: How does the manual model No.120-FWP differ from the automatic models (such as No.120-SAS or No.120-LABOT)?
A: รุ่น No.The 120-FWP model is operated manually, requiring the user to perform tasks such as cutting the plastic strand, weighing the sample, and cleaning the melt barrel; it is well-suited for moderate testing workloads. In contrast, the automated version utilizes a computer-controlled system to handle both the cutting of the extrudate and the cleaning of the barrel, making it ideal for high-volume testing and helping to eliminate operator-related variability.
