The document discusses how plastic industries can maximize machine utilization through quick changeover and setup techniques. It notes that with increasing customer demand for more product variants and shorter delivery times, having short lead times in production is necessary. This requires reducing changeover times between production runs. The document then lists benefits realized from reducing setup times, such as a 50% reduction in changeover time, 30% reduction in work-in-progress and finished goods inventory, and ability to manufacture 20 more new product varieties from existing equipment. Overall, quick changeover techniques can improve production flexibility and help companies face changing market demands and global competition.
