A lab instrument called a Melt Flow Index Tester is used to measure the flow of molten plastic under controlled weight and temperature conditions. It helps manufacturers in understanding the behavior of materials and selecting suitable plastics for processing. Consistent product quality and consistent molding are supported by this test. In order to maintain material consistency, reduce defects, and support reliable manufacturing processes, Perfect Group India Flow Index Testers are widely used in the plastic, polymer, and packaging industries.
