Abstract: A device is constructed for adjusting the concentricity of a die within an extrusion die assembly. The adjustment mechanism involves a series of compound screws having multiple operating threads that employ different pitches to generate a fine adjustment motion. The compound screws are coupled to opposing spring loaded plungers that move against a bias spring in reaction to movement of the compound screws.

Abstract: A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.

Abstract: A manifold is connected between an extruder and the associated die assembly to supply plastic flow to the die. The output from the extruder is split into multiple passages in which each manifold passage supplies plastic flow to an extrusion passage within the die assembly. An adjustable throttle valve is positioned within each manifold passage to regulate the flow volume through the manifold passage, thereby controlling the output of the die assembly. An adjustment mechanism is constructed having a lever arm actuated by a screw to provide movement of a spring biased part of the valve to open and close a valve seat against a valve stem.

Abstract: A die module is constructed for an extrusion die which provides for the adjustment of the concentricity of the exit configuration by allowing relative movement of the die within the extrusion die assembly. The die is mounted on a die holder through a pair of mounting rings which fit into a recess in the die body. The rings are constructed with interface surfaces having a curvature with a center upstream. The interface surfaces form a seat within which the die holder is contained with mating surfaces engaging the interface surfaces to allow pivot motion about the center of curvature of the interface surfaces. The engaging surfaces are in the shape of a partial hemisphere to simulate a universal motion. Adjustment bolts are located in the extrusion die assembly downstream of the interface. Bolts, which secure the rings to the die holder, are constructed to provide a fixed spatial relation of the engaging surfaces.
Abstract: A die is mounted within an extrusion die assembly to pivot with respect to the die body and thereby adjust the concentric position of the die with respect to the tip and the product to be coated. Spherical surfaces are formed in an intermediate support module to engage mating surfaces formed on the die holder. The spherical surface surround the die holder and are clamped together by screws which are limited in tightening, to avoid binding the pivotal movement between the spherical surfaces and the die holder.
Abstract: Using a balanced flow path, multiple layers of extruded plastic are supplied to a chamber having independently rotating surfaces. Said rotating surfaces apply a shear force to at least the inner and outer layers of said extruded plastic to orient said materials in said layers in different helical patterns, thereby forming a multi-layer tubular product in which at least inner and outer layers have different helical patterns to strengthen the product.

Abstract: The invention relates to an extrusion die assembly having a balanced flow path in which the die and tip modules cooperate to form an extended exit channel which communicates with an extrusion channel. The die is rotatably mounted on the die holder and the tip module is rotatably mounted within the axial bore. Each of the rotatably mounted components is independently driven by a motor. The motors are controlled to provide an infinite variation in relative rotational motion between the rotating components.

Abstract: In an extrusion die flow channels supply molten plastic to a pair of distribution grooves constructed in the upstream face of the die component adjacent to the die body. The die body becomes more universal and can be used for a variety of applications by replacing the die component with alternate designs of distribution grooves.
