Mfi Tester Manufacturer

Product Details

Digital Melt Flow Index Tester with Automatic Cutter | MFI & MFR Testing Machine Product Description The Digital Melt Flow Index Tester with Automatic Cutter by 4B Testing Equipments Pvt. Ltd. is a precision laboratory testing instrument designed to determine the Melt Flow Rate (MFR) or Melt Flow Index (MFI) of thermoplastic materials under controlled temperature and load conditions. The equipment is widely used for evaluating the flow characteristics, processing behavior, material consistency, and quality of plastic raw materials. This digital MFI tester is equipped with a high-accuracy digital temperature controller, digital timer, stable heating system, and motorized automatic cutter. The automatic cutter cuts the molten polymer extrudate at preset time intervals, helping achieve consistent sample lengths and improving test repeatability while reducing manual handling. The Melt Flow Index Tester is suitable for testing materials such as PP, PE, HDPE, LDPE, LLDPE, ABS, PS, PVC, Nylon, polymer compounds, masterbatch, plastic granules, and recycled plastic materials. Melt flow testing is commonly used for incoming raw-material inspection, production quality control, material comparison, and research applications. MFR/MVR testing is generally performed according to ASTM D1238 and ISO 1133 requirements. Key Features Digital Temperature Controller Digital Preset Timer Motorized Automatic Cutter Accurate and Stable Temperature Control PID-Based Temperature Control System Easy-to-Operate Control Panel Uniform Heating System High-Precision Test Barrel and Die Automatic Timed Extrudate Cutting Improved Test Repeatability Rugged and Compact Tabletop Design Suitable for Routine QC and Laboratory Testing Designed for MFI/MFR Testing ASTM D1238 and ISO 1133 Compliant Design Automatic Cutter Details The motorized automatic cutter is designed to cut the polymer extrudate automatically at a preset time interval. It helps maintain uniform test samples, reduces operator dependency, and supports accurate and repeatable Melt Flow Index calculations. Automatic cutting is a useful feature for routine quality-control testing where consistent sample collection is required.
