Rheology equipment given boost

Material testing equipment manufacturer Instron has developed a series of Rheology systems to determine the melt flow rates of materials.

Its Ceast MF30 is a single-weight system, designed to determine the melt mass-flow rate (MFR) and melt volume rate (MVR) in accordance with ISO 1133-1/-2 and ASTM D1238. A unique and versatile feature of the machine is its high-resolution digital encoder and controlled weight lifter. The lifter is equipped with an integrated load cell for controlled compacting and purging operations, a significant improvement for repeatability and time savings.

The Manual Mass Selector – a newly integrated option – simplifies configuration and testing, and ensures outstanding operator safety. With minimal physical effort, there is no heavy mass handling required and the configuration of the machine always remains the same.

The CEAST MF50 is the premiere Melt Flow Tester for single-weight and multi-weight tests. With outstanding features and a higher level of automation, it is compliant with the latest international standard requirements. During multi-weight tests, the system automatically applies up to five of the eight pre-installed test masses, ranging from 0.325 - 21.6kg, in any desired sequence. During the measurement, the temperature profile in the barrel is extremely stable and accurate according to ISO 1133-2.
