Temperature testing machine QC-661

for plasticsfor rubberindustrial

The specimen is given a fixed 10N force (or 50N) at the center with a standard Ø1 mm pin, and the temperature should increase by 50 degrees Celsius per hour. When the penetration depth of specimen reaches 1mm, the temperature is determined as the Vicat softening temperature(VST). The tester is equipped with touch screen that guides users step by step. During the process, the specimen holder and the weight frame automatically rise and descend to facilitate specimen’s installment and load calculation required by the test. A user-friendly interface and standardized process are designed to orientate users in the shortest possible and to reduce test errors. The display shows specimen temperature and LVDT displacement at each station. The temperature record stops when it reaches deflection value and the tester starts cooling down. Smart testing process is time-saving and requires only a minimum of testers. The test is suitable for material that is hard at room temperature. The specimen is 3 to 6.5 mm thick and the dimension is at least 10 x 10 mm or Ø10mm. Keywords: Heat Deflection Tester, Vicat Tester, Vicat Softening Point of plastic materials, H.D.T.
