PPO Production Scheduling and Shot Size Matching
문제 현상
When small PPO products are produced on large machines, degradation problems occur frequently, and when large products are produced on small machines, filling is insufficient; equipment and product matching is improper.
원인 분석
PPO is sensitive to residence time; small products on large machines cause the melt to reside at high temperature for a long time and degrade; large products on small machines have insufficient shot size and plasticizing capacity; the matching principle is that product weight accounts for a reasonable proportion of the machine.
해결 방법
①Match machine shot size according to product weight; ②avoid excessively large machines for small products; ③calculate plasticizing capacity to meet cycle requirements; ④consider material characteristic constraints in production scheduling.
핵심 요약
Machine matching in PPO production scheduling directly affects degradation risk; residence time management starts from equipment selection; production planning needs process participation.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
