PARA Mold Temperature Actual Measurement
Problem Phenomenon
Difference between PARA mold temperature display and actual measurement; the 120°C requirement is not truly met, with insufficient crystallization batches.
Cause Analysis
PARA requires cavity surface temperature of at least 120°C; difference between displayed and measured temperature; mold heating capacity; representativeness of measurement points; insulation loss.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Use a temperature probe to measure the actual cavity surface temperature; ②Verify reaching above 120°C; ③Evaluate mold heating capacity; ④Multi-point measurement representativeness.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Actual measurement verification of PARA mold temperature is the crystallization guarantee; displayed values are not trustworthy; multi-point measurement covers uniformity.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
