Applicable Standard : JIS K6300-2, ISO 6502
(Oscillating Sealed Flat Die Cavity Rotorless Curemeter）FDR (Flat Die Rheometer), manufactured by Ueshima Seisakusho Co., Ltd., is a high precision rubber vulcanization tester in conformity to Japanese Industrial Standard (JIS) and International Organization for Standardization (ISO). It gives small sinusoidal vibration that does not destroy the compounded rubber and expresses the torque that changes with the progress of vulcanization as a function of time (vulcanization curve), and shows the physical properties like minimum torque, the maximum torque, the scorch time, the vulcanization time and viscoelastic properties.
Application
●Measurement of vulcanization characteristics of compounded rubber along with the vulcanization process.
●Measurement of viscosity of raw and compounded rubber
Outstanding Features
●Excellent Temperature Control by 4HD (4 Heater Drive)
(Film Heaters are adopted and each of them is controlled by PID.)
・Shortened warm-up time.
・Shortened temperature recovery time after placing a sample.
・Excellent repeatability of test results.
●Compact and Lightweight (Minimized installation space)
●Conical drive, which adopts conical rotary movement, realizes an accurate sinusoidal oscillation.
●Simple Calibration System
・ Automatic Calibration of Load Cell by Electric Calibration System
・ Automatic Calibration of Phase and Torque by a Dynamic Calibrator
●Easy Operation and Data Management by PC
・ The measurement results can be easily exported to spreadsheet software like EXCEL, enabling easy preparation of reports, histograms and control charts.
●Unitization of Each Unit for Easy Maintenance
・ Heater, load cell and other input / output related amplifiers are unitized into a PCB in the machine.
・ Supply of units such as heater and temperature sensor
Measurement Principle
By placing compounded rubber between the upper and lower dies at a specified temperature, it measures torque which varies with rubber vulcanization while being subjected to sinusoidal torsional vibration. The vulcanization characteristics can be obtained while tracing changes in viscoelasticity during vulcanization process.
