Melt Flow Index Tester Manufacturer – Presto Group

Presto Group is a well-known manufacturer and supplier of melt flow index tester machines in India. Melt flow index tester machines are used to test the flow properties of molten plastics or resins. The melt flow index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures. MFI is an indication of the average molecular weight and viscosity of the polymer. A higher MFI value indicates a lower viscosity and a lower molecular weight, while a lower MFI value indicates a higher viscosity and a higher molecular weight.

Presto Group offers two models of melt flow index tester machines: Melt Flow Index Tester – NEO 2.0 and Melt Flow Index Tester – Deluxe. Both models are based on the test standards ASTM D 1238-1992, IS 2267-1972, IS 2530-1963, IS 10810-1984. Both models use a microprocessor-based PID controller that helps in automatic sample cutting. They also have a digital preset timer that provides highly accurate and precise testing results. They also have a digital steel barrel for uniform and consistent heating of the barrel/test cylinder.

Presto Group has more than 40 years of experience in providing quality testing instruments and solutions to customers across India and abroad. Presto Group has branches in Mumbai, Kolkata, Chennai and Delhi, and also exports its products to various countries. Presto Group is committed to delivering high-quality products and services at competitive prices.
