PARA Melt Temperature Actual Measurement
Problem Phenomenon
Difference between PARA melt temperature display and actual measurement; the 280°C standard is not met or exceeded, distorting the process benchmark.
Cause Analysis
PARA measured melt temperature should be about 280°C; difference between displayed and measured temperature; measurement method influence; melt uniformity; flame-retardant and impact-modified grades <270°C.
Solution
①Use a temperature probe moving in the melt for measurement; ②Standard grades about 280°C, modified grades <270°C; ③Standardize the measurement method; ④Melt uniformity verification.
Key Takeaway
Actual measurement of PARA melt temperature is the process benchmark; grade-differentiated settings; standardized measurement methods keep data credible.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
