A process of manufacturing a pulp molded cup lid includes making a pulp slurry; distributing the pulp onto a continuous screen wherein the pulp slurry is converted into a blank; feeding the blank and the continuous screen onto a first blanking die; moving a first blanking punch onto the first blanking die to dry the blank at a temperature of 160-180� C. for 2-5 seconds; causing the first blanking punch to exert pressure of 27-40 N/cm2 on the blank for 8-20 seconds; conveying the blank onto a second blanking die which is disposed under a second blanking punch; drying the blank, the second blanking punch, and the second blanking die at a temperature of 160-180� C.; moving the second blanking punch onto the second blanking die in 2-8 seconds; and causing the second blanking punch to exert pressure of 80-120 N/cm2 on the blank for 30-45 seconds. |
