No. 533 HDT Testing Device (Load Deflection Temperature Testing Machine)
This is a testing machine for evaluating the heat resistance of plastic materials (load deflection temperature / DTUL, Vicat softening temperature, ball pressure).
■It is safe because there are no cooling pipes installed in the oil tank. (※Water-cooled heat exchanger method) ■By adopting the heat exchanger method, the cooling speed is fast, allowing for a reduction in test cycle time. ■With the use of a chiller (※optional), rapid cooling is possible even in summer when the temperature of tap water is high.
