Evaluating melt flow rate (MFR) of plastics | MELT FLOW INDEX TESTER (MANUAL) / No.120-FWP

Overview of MELT FLOW INDEX TESTER (MANUAL)

This is a manual melt flow index tester designed to measure the “Melt Flow Rate (MFR),” which serves as an indicator of fluidity during the molding process of thermoplastics. The fluidity is evaluated by charging and melting the resin inside a preheated cylinder, applying a constant load, and measuring the amount (mass or volume) of the resin extruded from the bottom die. A key feature of this tester is its highly visible 5.7-inch full-color touchscreen. It eliminates complicated procedures and allows anyone to intuitively and easily perform tasks from setting test conditions to processing data.

Features

Rotary Encoder Standard-Equipped

Supports both Procedure A and Procedure B Testing in Standard Configuration

The rotary encoder is standard-equipped, allowing Procedure A and Procedure B testing in the standard configuration. Additionally, during Procedure A testing, the rotary encoder precisely tracks the piston position, ensuring accurate measurements between standard markings as required by respective test standards, regardless of the operator’s skill level.

Automated Sample Cutting

Pneumatic Procedure A Cutter

During Procedure A testing, molten samples are automatically cut. In melt flow testing, handling high-temperature samples is potentially hazardous as hands may come near heated areas, and sample temperatures are also high. Operator experience may also lead to variations in test results. The adoption of this automated cutter enhances safety and reduces human error.

Large Full-Color Touchscreen

Applicable for Validating Data Quality

Manual MFR testing requires precise timing. This model features a large, full-color touchscreen with high visibility, helping prevent operational mistakes during testing. Preheating and testing times (cutting intervals) are visualized with a progress bar, and the buzzer signals the cut timing, making operation easier. After testing, simply input the sample mass to automatically calculate, display, and save the MFR value. The device supports four languages: Japanese, English, Chinese, and Korean.
