MELT FLOW INDEXER
A new generation of Melt Index Test
The mi-2.x Melt Flow Index series can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures A, B and C. In addition it runs tests according to ASTM D 3364.
The mi-2.x easily performs melt-flow-rate (MFR), as well as melt-volume-rate (MVR) measurements. Due to the modular design of this system, it is possible to automate the measurement process step by step. The extrusion plastometer can be used either as a stand-alone instrument, or it can be run with a computer software for statistical analysis and data management. Depending on options, GOETTFERT Melt Flow Index machines offer additional benefits, besides from just running according to ISO and ASTM.
The melt flow indexer mi 2.1 shows fit for quality control (QC) where only one weight is used. In addition, it is useful when only a few measurements are made.
The Melt Flow Indexer mi2.2 is equipped with an automatic weight lifting system. This makes it much easier for the operator to handle weights of 5kg and more. As a time saving option, it also allows the automated start of the measurement right after the melt time is over. Weights can also be lifted at the end of the test, to allow an easy cleaning process.
The Melt Flow Indexer mi2.3 has a full weight handling system, whose cartridge holds up to 8 weights. There is no need anymore to lift or move weights manually.
A higher accuracy as well as a higher level of automazation are key advantages of the mi40.
The new mi40 can be operated via a flexible positionable touch panel which can be used directly at mi40 or can be moved flexibly and is therefore equally suited for a right and lefthanded person.
The mi40 can optionally be equipped with a semi-automated cleaning unit, with no use of compressed air, ensuring an efficient and reliable test barrel cleaning by means of up/down movements and rotating cleaning piston.
Operator comfort is increased additionally by the wellknown pre-compression function with test weights for more precise test results and by the ejection function at the end of the measurement.
As already known from the previous MI series, the test chamber is freely accessible to offer a large operating range for optimal material feeding and cleaning.
A link to the new miCONNECT is possible.
mi40 - automation
Our well established fully automated MI-Robo gets support by an ongoing development of fully automated melt flow index tests. We newly offer the possibility to operate our mi40 via an industrial robot, starting from automatic feeding of the test materials into the barrel, performing of the measurement and cleaning of the capillary fully automated. This solution enables a quality control with multiple Melt Flow Indexers (mi40) at the same time, with different materials and different testig conditions.
mi40 - viscosity
So far, our mi40 offers the possibility to carry out melt index tests with several weights (multi load measurements). An additional Add-on is the development of melt index multi weight measurements with the option of viscosity tests in an extended shear rate range.
The mi40 is also equipped with an OPC/UA Interface, which enables a bi-directional communication between various devices (machine-to-machine).
The world wide exclusive fully automated melt-index-instrument with automatic filling, measurement and cleaning.
By its high automation the Automatic Melt Indexer contributes to an even increased accuracy.
The reason for this high accuracy is the “operator factor” usually being an important issue, but here it is completely omitted during the fully automated melt flow tests of the MI-Robo contrary to manual and semi-manual operated MI devices.
The melt flow tests are according to the standards ISO 1133 and ASTM D1238.
The already well-established pre-compression function with test weights for more precise test procedure and test results and the ejection function for ejecting the test material at the end of the test contribute to a high user convenience.
The MI-Robo 89.16 is equipped with an integrated die cleaning function.
The die cleaning is automatically performed by the system and the die is directly available for
New features of the MI-Robo is the optimized replacement of the cleaning roll and the use of
electric motors instead of pneumatic motors. As a result, both, noise level and air consumption were reduced significantly
To complete the mentioned features we like to emphasize the accelerated weight selection and the optimized piston cleaning to provide fast availability of the weights and the test piston for subsequent test.
It is also possible to connect the MI-Robo 89.16 to an Online-Sampler for feeding test material directly from the production line.
The new Software Platform for Melt Flow Indexers.
With miCONNECT we start into the technological future of melt index measurements.
A server-based platform for comfortable service and evaluation of melt index test devices using a web browser-based user interface.
With OPC-UA, we rely on a common and secure industry standard for communication between device and software in order to keep smooth operation flexible and comfortable.
Measurement data can be stored and managed via Microsoft SQL Server or Microsoft Access and can therefore be scaled to meet any requirement.
Most important functions:
· Data transmission and data acquisition between PC and test device
· Location-independent operation
· Numerical and graphical display of the measured values with statistical evaluation
· Simple operation in a clearly designed graphical web interface
