PROCONE BLOWN FILM DIES OVERVIEW Davis-Standard ProCone Series of Blown Film Dies are designed for versatility, gauge uniformity and high rates. The stackable design uses spiral channels fed from a binary network that results in a unique, versatile arrangement with the ability to change structures. The spirals are designed to provide a balance between minimum residence time, pressure, reduced sensitivity to resin changes and uniform polymer flow. KEY FEATURES ■ Conical mandrel flow surfaces for all polymer distribution in a stacked mandrel configuration. ■ Two-piece mandrel and binary plate gives full angular and vertical position arrangement options. The layers are totally independent and can be moved. ■ Fully round distribution network from binary network to spiral start reduces traditional flow issues and associated feedport inserts. ■ Round flow passages are specifically designed to eliminate traditional degradation areas promoting fast purge and quick product change over. ■ High shear rates and low surface energy keep die surfaces clean. ■ Open center through die for high volume IBC or liquid insertion in water quench arrangement. ■ Excellent thermal isolation from IBC, preventing "cold"spots in die. ■ Die components to be fabricated from AISI 4140 steel, stress relieved, pre hardened forgings. ■ Minimum number of components offering uniform thermal expansion and symmetrical heat transfer, ensuring even properties for tightest possible gauge distribution and control. ■ All flow surfaces to be polished with the lips chrome plated, body and mandrel electroless nickel plated. ■ Additional mandrels can be supplied for specific polymers and rates for increased versatility.
