Why Injection Moulders Ask for MFI Before Buying Polymer? Melt Flow Index Explained | Presto

Why do injection moulders always ask for the Melt Flow Index (MFI) before purchasing a polymer? The answer lies in processability, product quality, and manufacturing efficiency. In this video, we explain why MFI (Melt Flow Index) is one of the most important properties of plastic raw materials. Learn how MFI indicates the flow behavior of molten polymers and why it directly impacts mould filling, cycle time, surface finish, dimensional stability, and mechanical properties. You'll also learn: What is Melt Flow Index (MFI)? Why polymer suppliers specify MFI values How MFI affects injection moulding performance High MFI vs Low MFI – Which is better? Selecting the right polymer grade for your application Common mistakes while choosing polymers based on MFI Importance of MFI testing in quality control Whether you're an injection moulder, plastic processor, quality engineer, or polymer manufacturer, this video will help you understand why MFI is a critical parameter before selecting any plastic raw material. #MeltFlowIndex #MFI #InjectionMoulding #PlasticTesting #PolymerTesting #QualityControl #PrestoStantest -- Presto Testing Instruments: Asia’s No.1 Lab Testing Instruments Manufacturer.
