New for Blown Film: Water-Cooled Bubble, High-Output Air Ring

摘要

W&H also displayed a more conventional means to cool blown film with the Opticool air ring. At the K 2007 show, W&H ran a three-layer line with a stacked (one atop another) air-ring configuration to boost output. This new dual-lip unit optimizes air-flow volume - said to exceed that of a tornado - to provide output rates exceeding that of the stacked units. At the open house, W&M ran the Opticool on a three-layer line with a 16-in. Maxicone C die at 2200 Ib/hr, holding gauge to ±2.5%.
