PCL mold temperature selection
Problem Phenomenon
PCL mold temperature high or low affects crystallization and surface, and selection lacks basis.
Cause Analysis
PCL mold temperature affects cooling rate and crystallization; high temperature gives good surface but long cycle; low temperature gives high efficiency but performance differences; product requirements; energy consumption.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Select mold temperature according to product requirements; ②Balance of crystallinity and surface; ③Cycle efficiency assessment; ④Temperature uniformity.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PCL mold temperature selection is a trade-off between performance and efficiency; requirement-oriented decision; uniformity ensures quality.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
