MS High Melt Temperature and Mold Temperature
Problem Phenomenon
MS melt temperature and mold temperature need to be set high to improve flowability and reduce internal stress, temperature management.
Cause Analysis
MS melt temperature and mold temperature need to be set high to improve flowability, reduce internal stress, and improve transparency and mechanical strength; melt temperature 200-230℃, middle 215-235℃, rear 140-160℃; mold temperature 30-70℃; temperature uniformity.
Solution
①Melt temperature 200-230℃ in sections; ②mold temperature 30-70℃; ③high temperature improves flow; ④uniformity management; ⑤actual measurement verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
MS high-temperature strategy is a balance of flowability and stress; sectional control is fine management; actual measurement ensures accuracy.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
