• 

  Full Automated Melt Flow Testing

  Capable of up to 12 sequential tests in a row*

  Simply set the sample-filled sample cup onto the carousel, set up the test conditions, and the actual testing will be done automatically. Not only the testing, but also cleaning after the test and calculation of results are performed automatically, allowing for up to 12 consecutive tests. This helps reduce variations in test results and saves the operator’s time spent on testing. We recommend this model for situations where a high frequency of daily tests and reproducibility of results are required.
  
  *Option of 24 tests and 50 tests are also available.

  Simple, Yet Robust

  Automatic mechanism with over 20 years of operational durability

  The full automatic and automatic models utilize a robot arm mechanism, offering a simple and space-saving design compared to similar products on the market. The mechanism, consisting of a robot arm and arm chuck, performs testing and cleaning with only rotational and vertical movements, minimizing complex actions and reducing error risks. Additionally, the core cylinder of the testing process is fixed in place, enhancing both safety and durability. Due to its simple design, the product is highly durable, and many units continue to operate reliably for over 20 years.

  Yasuda Seiki’s Unique Sample Cup

  Accommodates various sample shapes and material properties

  The specially developed sample cup used in the automatic and full automatic models allows for direct sample loading into the cylinder. It can handle a variety of sample shapes, including pellets, granules, flakes, sheets, and strips. Additionally, it can accommodate difficult-to-measure powdery samples. The standard sample cup is coated with Teflon on the inner wall, improving its sliding properties for easy loading. For gummy samples, there is an option to replace the inner lining with a Teflon tube.

  High-Performance Procedure A Cutter & Automatic Weighing Device

  Automates sample cutting and mass measurement

  This option automates everything from sample cutting to mass input and MFR calculation of procedure A testing. Yasuda Seiki’s uniquely designed Procedure A Cutter can handle a variety of resin types. After cutting, the sample is cooled by air blow, and the weighing device measures the cut sample’s mass, transfers the measurement value to the software and automatically calculates the MFR value.

  MVR Graphing During Testing

  Applicable for validating measurement data

  In melt flow testing, air bubbles mixed into the molten resin during extrusion can cause variability in flow characteristics and affect test results. Yasuda Seiki has developed software that records MVR changes over time along with the test results, using a high-resolution rotary encoder to precisely track piston movement during testing. If air bubbles (entrapped air) are present, this appears as an anomaly in the MVR graph, allowing operators to assess the validity of test results post-test.

  Powerful Extrusion Mechanism

  Extrudes residual material with a 30kW motor output

  For materials with a low flow rate, extruding residual samples after testing can be the most labor-intensive task in MFR testing. The vertical-axis motor, a design shared between the automatic and full automatic models, ensures complete extrusion of residual material, even with low flow rates materials. This feature enables safe and effective residual material removal and cylinder cleaning after measurement.

  Excellent Running Cost Efficiency

  Low running cost with only gauze being a primary consumable

  Under standard testing conditions, the only consumable needed to run the tester is gauze rolls for cleaning the cylinder and test piston, keeping running costs low.
  *In the long term, parts such as the die and piston may require replacement depending on wear.
