At K 2013, Instron will be showcasing, on stand J18 in Hall 10, measuring and testing systems for determination of the rheological properties of plastics and evaluation of the behaviour of materials and components under static and dynamic loads. Amongst the exhibits will be the CEAST MF50 melt flow tester, and the new CEAST MF30 with manual mass selector, a CEAST 9050 pendulum impact tester, and a CEAST 9350 drop weight tester.
The group will also be presenting automated testing systems, accessories, and software for the laboratory and the shop floor. This includes the new AutoX750 Automatic Contacting Extensometer, the TrendTracker software package, and an automated carousel system for tensile testing that features a precision measuring system for determining specimen thickness.
The CEAST MF30 and MF50 are part of Instron’s new melt flow tester series. The CEAST MF30 is a single-weight system, designed to determine melt mass-flow rate (MFR) and melt volume rate (MVR) in accordance with ISO 1133-1 and -2 Procedures A, B, C, and ASTM D1238. It features a high-resolution digital encoder and a N/C-controlled weight lifter. The lifter is equipped with an integrated load cell for controlled compacting and purging operations.
The CEAST MF50 is a melt flow tester for single-weight and multi-weight tests. It is claimed to be compliant with the latest international standard requirements for temperature accuracy and stability. During multi-weight tests, the system automatically applies up to five of the eight pre-installed test masses, ranging from 0.325 - 21.6 kg, in any desired sequence. During the measurement, the temperature profile in the barrel is accurate to ISO 1133-2. The CEAST VisualMELT Software controls all functions of the tester during single-weight and multi-weight tests.
The CEAST 9350 is a floor-standing impact system designed to deliver high impact energies from 0.59 -750 J. The system can be used to test a variety of specimens and is suitable for a range of impact applications including tensile impact tests, puncture tests, or tests to Izod and Charpy.
The new AutoX750 is a high-resolution automatic contacting extensometer which meets the requirements for ISO 9513, ASTM E83, and ISO 527-1 (2011). Features include automatic gauge length positioning, adjustable contact force with a reference label, and multiple knife-edge options to accommodate different materials.
Also on display will be TrendTracker, a new software package for Bluehill Software, which accelerates the data analysis workflow of a lab by allowing the user to search and analyze test results across multiple samples tested over time and on various test frames. The results are automatically exported to a robust and scalable database.
Finally, the group will discuss its automatic carousel feeding system, which it claims may reduce the time and effort required for performing standardised tests on tabletop tensile testers from the Instron 5960 Series. An optional digital measuring system is now available to capture the thickness of all specimens at several points over the length of the specimen with an accuracy of 1 µm. It then transmits the values through an RS 232 interface to the Bluehill 3 Materials Testing Software.
