FDR Rheometer

FDR (Flat Die Rheometer) is a testing machine that measures torque that changes as rubber is vulcanized when sinusoidal torsional vibration is applied by putting blended rubber between the upper and lower dies of a flat plate at a specified temperature, and requires vulcanization characteristics from changes in maximum torque, minimum torque, scorch time, vulcanization time, viscoelasticity, etc., and uses a cone drive to obtain accurate sine wave vibration and the adoption of a 4Heater Drive, which has excellent accuracy and reproducibility of test results It has been realized.

Furthermore, it is a state-of-the-art vulcanization tester that has been assembled into a compact shape regardless of the installation location due to a thorough layout design of each component.

Furthermore, foam pressure measurement specifications and program heating specifications that can analyze the foaming pressure of foam rubber and the foaming reaction and vulcanization reaction have also been prepared as options.

The flat dirheometer (FDR) is designed to analyze the behavior of rubber during the vulcanization process in detail, and accurately measures changes in maximum torque, minimum torque, scorch time, vulcanization time, and viscoelasticity. This makes it possible to clearly grasp vulcanization characteristics, which are essential for product quality control. By adopting a cone drive and 4Heater Drive, the reproducibility and accuracy of test results have been dramatically improved.

The flat dirheometer (FDR) is a testing machine developed to strictly monitor the vulcanization process of rubber products, and specializes in vibratory torque measurement. This device measures torque fluctuations during vulcanization in real time by inserting compound rubber between heating dies arranged one above the other and applying sinusoidal torsional vibrations. This quantifies maximum torque, minimum torque, scorch time, and vulcanization time, which are important rubber characteristics, and also evaluates dynamic changes in viscoelasticity. Users can acquire extremely high accuracy data using cone drive and 4Heater Drive technology.

The test temperature can be set in a wide range from 50℃ to 230℃, and the installation space required by the equipment can also be stored compactly, making it suitable for factory environments under any conditions. Also, with optional functions, it is possible to measure the foaming pressure of foam rubber and mutual analysis of the foaming reaction and vulcanization reaction.

This device meets test standards in accordance with JIS K 6300-2 and ISO6502, and is equipped with an overload function of 22 N·m or more. The dimensions are 333 mm (width) x 520 mm (depth) x 780 mm (height), and the design emphasizes ease of handling while being highly robust.
