PBT mold temperature 50-75℃
Fenómeno del problema
Uneven product crystallization, poor surface gloss, or bending deformation caused by uneven cooling
Análisis de la causa
PBT crystallizes fast and cooling time is short, mold temperature 50-75℃ is appropriate; too low mold temperature causes insufficient crystallization and uneven cooling easily causes bending; high mold temperature improves crystallization and surface quality
Solución
①Control mold temperature at 50-75℃; ②appropriately increase mold temperature for warpage-sensitive parts; ③uniform control by mold temperature controller to prevent temperature difference; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PBT's fast crystallization determines the short cycle advantage; the 50-75℃ mold temperature range is the balance between crystallization quality and deformation control; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
