Based on your previous focus on temperature sensor block wear and corrosion assessment and calibration accuracy control in hot runner scenarios, you can accurately select the appropriate hot runner temperature sensor block based on three core dimensions:
Matching Temperature Measurement Accuracy Requirements: For conventional injection molding, a standard K-type thermocouple temperature sensor block with an accuracy of ±1℃ is sufficient. For precision injection molding, choose a platinum resistance thermocouple temperature sensor block with high thermal conductivity and an accuracy of ±0.3℃ to meet high-precision temperature control requirements.
Matching Operating Environments: For injection molding of special engineering plastics with high wear and high corrosion, select a temperature sensor block with a wear-resistant alloy protective coating to avoid probe corrosion and wear due to prolonged contact with high-temperature melt.
Matching Installation Structure: Select a temperature sensor block with the corresponding installation size according to the hot runner layout, ensuring that the sensing surface is in close contact with the outer wall of the runner to avoid thermal lag caused by installation gaps, while also reserving sufficient wiring space.
When selecting a temperature sensor block, prioritize matching the core requirements of your specific injection molding scenario; there is no need to excessively pursue high parameters and waste costs.
