Following ASTM D1238, Instron's CEAST MF50 tester with a piston holding device can be used to test high fluidity of molten thermoplastics.
A CEAST Capillary Rheometer has been used to test the flow behavior of plastic cap liners of bottle cap to prevent leaks with a tight mold and quality seal.
Melt Flow Testers with load cells increase repeatability of testing Melt Flow Rate and Melt Volume Flow Rate in accordance with ISO 1133-2 and ASTM D1238.
Testing with CEAST Capillary Rheometers and Visual RHEO Software allows manufacturers to understand the change in polymer viscosity related to time.
With a CEAST SR50 Capillary Rheometer, Instron was able to test silicone materials to determine which can undergo extrusion at room temperature, observing ISO 11443.
Low viscosity fluid with a high-shear environment for spray application can be tested with an Instron CEAST SR20 capillary rheometer.
A controller can test how much a mold will shrink by placing it in a high-pressure chamber with controlled temperature, volume, and pressure, following ISO 17744.
Instead of manual cleaning methods, the Integrated Barrel Cleaning Device is used to easily clean Melt Flow Testers after every test to ensure accuracy.
