TPE Mold Temperature SBS/SEBS
Problem Phenomenon
Poor surface gloss and large internal stress of products, or prolonged cycle due to excessive mold temperature
Cause Analysis
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
Solution
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
Key Takeaway
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
