Melt Flow Index Tester Working Principle
Melt index meter The flow rate meter uses a high-temperature heating furnace to make the measured object reach a molten state under a specified temperature condition. The test object in this molten state is subjected to an extrusion test through a small hole of a certain diameter under a prescribed weight load. In the research of plastic production and scientific research units of industrial enterprises, the “melt (mass) flow rate” is often used to express the fluidity, viscosity and [...]
