I. Scenario of Batch Calibration of 16-Cavity Precision Medical Component Hot Runner System
Application Background: A precision injection molding factory's 16-cavity medical consumable mold hot runner system was experiencing issues. Calibrating each of the 16 temperature control channels sequentially took over 2 hours, and time reference deviations existed between channels calibrated at different times, resulting in poor channel temperature consistency and a product yield of only 92%.
Synchronization Solution: Eight 2-channel hot runner signal generators were used to achieve multi-channel synchronous cascading, outputting 16 synchronized K-type thermocouple standard temperature analog signals at once, covering the entire operating range of the hot runner from 0 to 300℃.
Implementation Results: Synchronization deviation across all channels ≤0.01s; total batch calibration time reduced from 2 hours to 20 minutes; channel calibration consistency improved by 90%; product yield increased to 98.5%.
II. Verification Scenario for Filling Timing of Needle Valve-Type Multi-Cavity Hot Runner Automotive Components
Application Background: Needle valve-type hot runner multi-cavity automotive structural component molds have long suffered from slow filling in local cavities and product weight deviations exceeding 3%. Conventional troubleshooting methods cannot pinpoint the hidden timing deviations.
Synchronization Solution: A multi-channel synchronization signal generator is used to synchronously output 12 pulse trigger signals to 12 needle valve drive modules, simulating gate opening actions under different timing offsets.
Implementation Results: Two needle valve channels with a lag of 0.08s were accurately located. After fine-tuning the timing parameters, the weight deviation of filling in all cavities decreased from 3.2% to 1.2%, completely resolving the slow filling fault in local cavities.
III. Batch Testing Scenario for Anti-interference Performance of 24-Cavity Hot Runner Systems in Consumer Electronics
Application Background: Strong electromagnetic interference sources such as frequency converters and servo motors exist around the hot runner production line. During mass production, occasional temperature control channel signal drift leads to batch product appearance defects.
Synchronization Solution: A multi-channel synchronization signal generator synchronously injects in-phase simulated interference pulse signals into all 24 temperature control channels to simulate signal interference scenarios under complex electromagnetic environments.
Implementation Results: The system successfully completed full-channel anti-interference testing in one go, quickly identifying three channels with substandard anti-interference capabilities. Hardware modifications were completed ahead of schedule, and no further issues caused by signal drift occurred during subsequent mass production.
IV. Data Synchronization Interaction Scenario between Hot Runner Temperature Control System and MES System
Application Background: When interfacing the hot runner temperature control system with the MES system, occasional data corruption and timing misalignment issues occurred, making it impossible to trace the consistency of channel temperature data upload times.
Synchronization Solution: A multi-channel synchronization signal generator synchronously outputs stepped standard temperature signals to all temperature control channels, synchronously collecting the data upload timestamps of each channel on the MES system.
Implementation Results: Two channels with data upload delays exceeding 0.5 seconds were accurately identified. After optimizing the communication configuration, the data upload time consistency across all channels reached 99%, completely resolving the occasional data corruption issues that previously occurred during interfacing.
