Also known as a Melt Flow Index Tester or Melt Index Plastometer — available in manual and computerized (KayJay 2006 AC) models.
The Melt Flow Indexer is one of the most widely used instruments in plastic and polymer quality control. It determines the melt flow rate of a thermoplastic by extruding the molten material through a precision die under a specified load and temperature. The mass of polymer extruded in a fixed time (usually 10 minutes) is reported as the Melt Flow Index in grams per 10 minutes (g/10 min), giving a quick, reliable indication of a material’s molecular weight and flow behaviour.
Because melt flow rate directly affects how a polymer processes during injection moulding, extrusion and blow moulding, MFI testing is essential for incoming raw-material inspection, batch-to-batch consistency, compound and resin development, and the evaluation of recycled material. International Equipments manufactures the Melt Flow Indexer in both a robust manual model and a fully computerized model (KayJay 2006 AC) that automatically calculates MFR and MVR, stores results and improves repeatability.
