Melting Index Meter (CEAST MF50 Multi Weight)

Instron ® The CEAST MF50 multi weight testing machine conducts melt index testing in accordance with ASTM D1238 procedures A, B, C, D and ISO 1133 A and B MFR and MVR procedures, and performs single weight and multi weight measurements in one test. The multi weight test can include up to 5 weights arranged in ascending, descending, or any order, and its preheating and measurement steps are fully customizable.

I. Overview

Instron® CEAST MF50The multi weight testing machine fully complies withASTM D1238programA, B, C, DandISO 1133 AandBofMFRandMVRThe program conducts a melt index test, with single weight and multi weight measurements conducted in one experiment. The multi weight test can at most include those arranged in ascending, descending, or any order5The preheating and measurement steps of a weight are completely customizable. The machine pre installs and manages all weights without any operator intervention, without considering any safety issues. High resolution direct contact encoder measures piston displacement and maintains stable and accurate temperature distribution inside the cylinder. Additional advanced features include a large touch screen for testing programming, management, and diagnostic functions, with features based onWindows CEThe Embedded SystemPC, able to store and pass throughUSBOr directly connect to Ethernet to easily export the entire set of parameters and test results. The tilted cylinder is easy to clean and inspect, and the unique load sensor (maximum load)750 N）Provide support for compaction and blowing functions. Automatic cutting, automatic cleaning, and mold expansion accessories can also be provided.

2、 Characteristics

• ●The inclined bracket installed on the furnace allows operators to easily clean and inspect the material cylinder after the experiment
• ●Equipped with a fully automatic system for loading weight blocks onto pistons, it can load individual weight blocks or any combination of weight blocks for multiple tests
• ●including0.325 - 21.6 kgEight different weight blocks (selected from the recommended mass blocks in international standards)
• ●Can be used in the same experiment in ascending, descending, or any order at most5Multiple measurements using a single weight
• ●High resolution CNC lifting, quickly and accurately applying weights
• ●High precision encoder ensures the accuracy of the results and is used in a single experiment50A measurement point
• ●A powerful fully integrated semi-automatic cleaning system can be added to the instrument for fast, convenient, and effective cleaning
• ●A mold insertion device can be provided for testing high fluidity materials to prevent material from flowing out before the start of the test, controlled by a micro switch to prevent safety issues
• ●A unique load sensor used for material compaction ensures high repeatability of results, effectively eliminates bubbles generated during the preheating stage, and drives the material at the end of the experiment.
• ●Can provide special molds that comply with specific procedures (such as forPVC，ASTM D 3364）
