ASTM D 1238-1992 Standard Testing Instruments

ASTM D1238 1992 specifies the standard test method used for determining the melt flow rate and melt volume rate of thermoplastic materials through extrusion plastometer testing. The standard helps manufacturers study the flow behavior, processing characteristics, viscosity, and consistency of plastic resins under controlled temperature and load conditions. It is widely used in polymer, packaging, automotive, and plastic processing industries for raw material inspection and production quality control. ASTM International Presto Laboratories offers advanced melt flow index tester systems suitable for ASTM D1238 testing applications. These testing systems help industries examine polymer flow properties, material consistency, and processing performance under controlled laboratory testing conditions.

Melt Flow Index Tester - Deluxe

Melt Flow Index Tester - Deluxe

Presto Melt Flow Index Tester is used for evaluating the flow properties of molten plastics or resins. The Melt flow Index of thermoplastic materials is defined as the rate of flow (in grams per ten minutes) of extrudates of molten resins through a jet of a particular length and diameter.

Melt Flow Index Tester - NEO 2.0

If you are working in the plastics or polymer industry, then you should be aware that it is important for manufacturers to test the melt flow rate of these materials. The melt flow rate of the materials is considered to be the measure of the flow of polymers when it will be melted. The result of the melt flow rate will be reported as the weight of the polymer that will flow through the orifice in a certain period of time.
Melt Flow Index - Melt Volumetric Rate Model (Method - A & B)

Melt Flow Index - Melt Volumetric Rate Model (Method - A & B)

The new-design MFR - MVR Model can quickly extrude the flow rate of molten resins utilizing the advanced setup of load, piston, and a metallic barrel. The specimen, majorly in granule form is put inside the barrel and the piston is inserted. Loads, as per requirement are placed on the piston and the parameters are then selected from the touchscreen display.

Melt Flow Index - Junior

The melt flow rate of the polymers is one of the essential properties of the materials that will help the manufacturers in determining the rate at which it flows. This property of the material is important as it provides the necessary data on the mass flow rate of the polymer. Thus, to test the melt flow properties of the materials, we at Presto have recently designed a high-quality Melt Flow Index Junior model.
