Based on your previous focus on the graded repair and calibration control of wear and corrosion of temperature sensors in hot runner scenarios, the lifespan of a repaired temperature sensor is affected by the degree of damage and operating conditions. Here's a breakdown:
Minor Damage Repair: Temperature sensors with only the oxide layer polished and thermal grease applied can last 1-2 years under normal non-corrosive injection molding conditions, almost the same as a brand-new part.
Moderate Damage Repair: Temperature sensors with the sensing surface milled and alloy lining added have a lifespan of approximately 6-12 months. Temperature measurement accuracy needs to be calibrated every 3 months to prevent performance degradation.
High Corrosive Conditions: Under conditions containing glass fiber or corrosive engineering plastics, the lifespan after repair is only 3-6 months. Regular inspections are recommended to promptly identify and address any performance abnormalities.
If a brand-new temperature sensor element is replaced during repair, the lifespan under normal operating conditions can be restored to near-new parts.
