Conclusão principal
LCP high-speed filling has extremely high venting requirements; venting design must be sufficient.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
