TPE Mold Temperature SBS/SEBS
Fenómeno do problema
Poor surface gloss and large internal stress of products, or prolonged cycle due to excessive mold temperature
Análise das causas
TPE mold temperature is graded by system: SBS system 10-40℃, SEBS system 35-65℃; higher mold temperature promotes flow and improves the surface, and low-pressure injection can also fill the mold
Solução
①SBS system mold temperature 10-40℃, SEBS system 35-65℃; ②Take the upper limit when surface requirements are high; ③Precise control by the mold temperature controller; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
TPE mold temperature is managed by system grading; SBS low temperature, SEBS medium temperature, balancing surface quality and cycle; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
