PEI Mold Temperature Uniformity
Fenómeno del problema
Uneven PEI mold temperature causes warpage and surface differences; temperature difference exceeds the standard; high-temperature mold management is difficult.
Análisis de la causa
PEI mold temperature is 140~180℃ and requires uniformity, with temperature difference ≤10℃; high-temperature mold thermal balance is a challenge; heating and cooling system matching; representativeness of temperature measurement.
Solución
①Set mold temperature at 140~180℃; ②control temperature difference ≤10%; ③configure high-temperature oil temperature machines; ④verify by actual measurement of the mold cavity surface.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
Uniformity management of PEI high-temperature molds is meticulous work; the 10℃ temperature difference standard is quantified; actual measurement verification is more reliable than settings.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
