This device plays a key role in determining how thermoplastic materials behave under specific processing conditions — offering insights that directly influence manufacturing efficiency and product performance.
At Pacorr Testing Instruments, we specialize in developing high-precision testing equipment that meets global standards. Our Melt Flow Index Tester is specifically designed to help manufacturers evaluate the flow properties of plastic materials with confidence and ease.
What is a Melt Flow Index Tester?
A Melt Flow Index Tester (MFI Tester) is a laboratory device used to measure the melt flow rate (MFR) of thermoplastics. This value indicates the rate at which a polymer melts and flows through a standard-sized die under controlled temperature and pressure conditions. The result is typically expressed in grams per 10 minutes, representing how much material passes through during the test duration.
The method is governed by international standards such as ASTM D1238 and ISO 1133, making MFI testing an essential practice for material validation and process control.
Why is MFI Testing Important?
Understanding how a plastic material flows when heated is fundamental to many applications. The Melt Flow Index reveals important characteristics about a polymer’s viscosity and processing behavior. Here’s why MFI testing is so valuable:
Batch Consistency: Ensures raw materials maintain consistent flow properties, reducing defects in finished products.
Material Selection: Helps engineers choose the right type of polymer for specific molding or extrusion processes.
Quality Control: Detects contamination, degradation, or formulation errors early in the production line.
Cost Efficiency: Reduces waste and processing time by optimizing production parameters.
Regulatory Compliance: Required by many industry and international standards for product certification.
