Instrument use：

It is used to analyze and study the melt flow rate of thermoplastics under certain conditions.

Standards compliant：

Comply with GB/T9643, GB/T3682.1, JB/T5456, ISO1133 and other standards.

Features：

1. Using PID intelligent temperature control, the temperature control accuracy is high, which can ensure that the temperature at the top 10 mm of the die in the barrel is within ±0.5℃

2. The key parts are nitrided, with high strength, hardness and small deformation characteristics, and ensure the accuracy and stability of the measurement data;

3. The heating speed is fast. The heater of the instrument adopts a special spring heating ring for hot runner. Its main material is imported nickel-chromium wire alloy, which is better than traditional dynamic heaters.

4. Stronger dry burning resistance, higher power, better heating uniformity and long service life, supporting the instrument to work for a long time at the highest temperature of 450 ℃;

5. The instrument heating adopts a voltage regulating module, which can adjust the voltage and power in a full range. Compared with the traditional solid-state relay on-off control, the heating is more stable and rapid, so that the constant temperature state can be quickly restored after filling;

6. The instrument adopts a customized armored platinum resistance temperature sensor with the highest accuracy class A, and the accuracy is within 0.1℃. Compared with traditional sensors, it has the characteristics of impact resistance, corrosion resistance, vibration resistance, and can be bent at will. Longer life, can ensure the long-term use of the instrument under the highest temperature of 450 ℃ environment.
