The Melt Flow Index (MFI) Tester is designed to determine the flow rate and melting temperature of thermoplastic polymers. This test helps in evaluating the viscosity and process ability of plastic materials.

1. Heating & Control System

✔ Temperature Range: 190°C to 375°C (Adjustable as per material requirements)
✔ PID Digital Temperature Controller for precise heat regulation
✔ Uniform Heating System for stable test conditions

2. Standard Weights & Load Mechanism

✔ Interchangeable Test Weights (as per ASTM, ISO, and IS Standards)
✔ Load range: As per test material specifications
✔ Pneumatic or manual weight application system (optional)

3. Automatic Cutting & Timing Mechanism

✔ Auto Cut-Off Knife for precise sample shearing at pre-set intervals
✔ Digital Timer & Stopwatch for accurate measurement of flow rate
✔ Weight-based extrusion measurement for repeatable results

Scope & Applications

The Melt Flow Index (MFI) test is widely used in the polymer and plastics industry to measure the ease of flow of molten plastic materials. It is an essential parameter for:

✔ Material selection & quality control in polymer manufacturing
✔ Plastic moulding & extrusion process optimization
✔ Comparative analysis of different thermoplastic materials
