    Abstract: Apparatus and methods for extruding plastic materials are disclosed. An exemplary apparatus comprises: a feeding portion; a melting portion in communication with the feeding portion and configured to transmit heat into material received from the feeding portion; and an output die in communication with the melting portion to permit extrusion of the material. The melting portion comprises: a melting barrel having an inner surface defining a melting chamber in communication with the feeding portion; and a melting insert inside the melting chamber. The melting insert comprises an outer surface in contact with the inner surface of the melting barrel where the outer surface comprises one or more open-ended channels formed therein. In some embodiments, the feeding portion and the melting portion may be thermally insulated from each other and a propeller of the feeding portion may be disposed entirely outside of the melting portion.

    Abstract: An annular die has a mandrel having a spiral groove formed in a surface of the mandrel that distributes a flow of liquid across the mandrel surface and directs the flow of liquid in a flow direction across the spiral groove and across the mandrel surface. At least a portion of the spiral groove has a cross-section configuration where an interior surface of the spiral groove portion is oriented toward the flow direction as the interior surface extends to and intersects with the mandrel surface. The annular die has particular, but not limited, application as a blown film die.

    Abstract: The invention relates to a film extrusion die (1) for producing a single-layer or multilayer blown film. Said film extrusion die (1) comprises at least one melt gap (4) for forming a film layer, said melt gap (4) being formed between two boundary walls (5, 6). At least one melt line (22) opens into the melt gap (4) and becomes a first melt duct (4) within the melt gap (4), said melt duct (4) being formed by recesses (3, 7) in the two boundary walls (5, 6) of the melt gap (4) in at least one sub-section (11, 12, 13, 14) of the extension of the at least one first melt duct (10). The melt duct (10) distributes the melt in the melt gap (4) while tapering in the direction of travel of the melt (4) and merging entirely with the melt gap (4) in the end region (14) thereof (10). The novelty and inventiveness is considered to lie in the fact that in one of its sections (11, 12, 13, 14), the at least one first melt duct (10) is formed exclusively by recesses (3, 7) in one of its two boundary walls (5, 6).
