#107 Melt Flow Rate (MFR) of Plastics | Technical Tutorial ...

The melt flow rate is measured by putting the plastic resin under test in a testing equipment called a melt low indexer, heating the plastic resin, making the molten plastic resin with a prescribed weight to flow, and measuring the weight of the plastic that flows out as an index of the melt flow rate. The method of this test has been stipulated in JIS and ISO standards.

Shrinkage Value of Plastics Material & Injection Molding - Chart

The shrinkage rate is strongly depending on the polymer composition & material properties (PVT, thermal properties…), itself but also on the processing conditions (temperature, pressure, flow rate etc.) applied and part design & geometry (Wall thickness, gate location, mold constraints).
