This is an automatic 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.
- This is an automatic 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. This tester automates the entire process – from running the test to the troublesome task of cleaning the cylinder – as a single full cycle. This significantly reduces the operator’s workload and enables more consistent and stable testing.

- Automatic Weight Loading Device
- In melt flow testing, test loads over 10 kg are required depending on the material, and manually changing the weights can be both burdensome and hazardous. The Automatic Weight Loading Device automates load changes, reducing the physical strain and risk for operators. Additionally, it automatically switches loads based on registered test conditions, allowing continuous testing of samples under different test parameters.
