Thermocouple

I. Immediate Inspection After Installation (Within 1 Hour of Cooling to Room Temperature): After the nozzle has naturally cooled to room temperature and thermal stress has fully released, immediately

I. Key Advantages of This Timing: At this point, the nozzle has completely cooled from its 280℃ hot-fit temperature, the internal stress caused by thermal expansion and contraction has been fully rele

I. Key Advantages of This Timing: At this point, the nozzle's overall thermal expansion is complete, and the interference fit between the lining and the H13 steel substrate reaches a stable high-t

I. High-Temperature Operation Safety Precautions Wear thickened heat-resistant gloves with a temperature resistance of 350℃ or higher. Do not touch the metal casing of the nozzle with bare hands to av

I. Preparation Time (1 hour) Heating the hot runner from room temperature to its rated operating temperature of 320℃ at a safe rate of 50℃/h takes approximately 1 hour. After heating, maintain the tem

The installation quality of hot runner thermocouples directly determines temperature measurement accuracy and service life. However, many on-site operators often make various irregular installation mi

The thermocouple is the core sensing element of the hot runner system, and its selection directly determines temperature control accuracy, system stability, and service life. Choosing a suitable therm

Regular calibration is essential for maintaining temperature measurement accuracy in hot runner systems. Calibration should be performed every 3 to 6 months to correct gradual drift errors and restore

The connection between the thermocouple and the temperature controller is not a trivial matter. Using incorrect extension wire is one of the most common yet frequently overlooked errors in hot runner

Industrial injection molding environments are filled with electrical noise that can disrupt thermocouple signals and cause unstable temperature control. Heater elements, servo motors, and variable fre

Ground loop interference is one of the most common difficult-to-eliminate signal faults in multi-cavity hot runner molds. It occurs when different components in the mold and temperature controller sha

Regular maintenance extends thermocouple probe service life by 2 to 3 times compared to unmaintained systems. A systematic maintenance program covering daily visual checks, weekly cleaning, monthly ca
