Melt Flow Index Tester – Accurate Polymer Testing for Quality Assurance
Pacorr’s Melt Flow Index Tester (MFI Tester) is an advanced testing instrument designed to evaluate the flow properties of thermoplastic polymers. In the plastics industry, maintaining the right melt flow rate is essential for ensuring consistency, durability, and processing efficiency. With global standards like ASTM D1238 and ISO 1133, Pacorr’s MFI Tester offers manufacturers precise data to maintain product quality, compliance, and process optimization.
What is a Melt Flow Index Tester?
A Melt Flow Index Tester is a specialized testing machine used to measure the rate of extrusion of molten thermoplastic materials through a standardized die under controlled temperature and pressure conditions. The result, known as the Melt Flow Index (MFI), is expressed in grams per 10 minutes.
This property helps manufacturers determine:
Polymer viscosity and flowability
Suitability for injection molding, extrusion, and blow molding
Batch-to-batch consistency
Material selection for specific applications
Why is MFI Testing Important?
In polymer industries, slight variations in raw material properties can cause defects in final products such as weak mechanical strength, poor surface finish, or inconsistent dimensions. The MFI Tester helps prevent these issues by:
Ensuring raw material quality control
Providing reliable data for research & development
Reducing manufacturing defects and rejections
Complying with international testing standards
Supporting cost-effective production

Applications Across Industries
The Melt Flow Index Tester is widely used in industries such as:
Plastic raw material manufacturers – For resin and granule testing
Automotive industry – Ensuring durability of polymer parts
Packaging industry – Testing polymers for bottles, films, containers
Electronics & electrical – Verifying polymer strength and insulation properties
Medical devices – Guaranteeing safety and reliability of polymer components
How Pacorr MFI Tester Works
A polymer sample is heated to the required temperature inside the barrel.
A specified load weight is applied on the piston.
The molten polymer flows through a standard die.
The amount of material collected in 10 minutes is weighed.
The result (in grams/10 min) defines the Melt Flow Index.
Higher MFI → Lower viscosity → Suitable for thin-wall molding
Lower MFI → Higher viscosity → Suitable for structural components
