摘要： An extrusion pelleting process and apparatus is disclosed wherein the outermost portion of an extrusion orifice is surrounded by a heat reservoir maintained at a temperature significantly higher than the softening temperature range of the polymer being extruded. The high temperature heat reservoir constitutes a heat source from which individual extrusion orifices may be heated above the polymer's softening range to assist in melting frozen plugs of polymer which may block the orifice from time to time.Also disclosed is a heat flow control mechanism, in effect, for slowing the heat release from the reservoir to the individual extrusion orifices for economy of operation while still making available such high temperature source for unfreezing such plugs.

摘要： A collimated hole structure formed by constricting a plurality of tubular elements each provided with a core for supporting the tubular element during the constricting operation. The bundle of elements is constricted to a point where the elements effectively fuse into a substantially monolithic body. The cores are then removed, leaving a plurality of extremely small diameter, generally parallel passages in a solid body. The tubular elements may be arranged in any desired array, and thus the passages may be provided similarly in any desired array. The passages may have high aspect ratios and may be closely juxtaposed. In one illustrative application, the collimated hole structure is provided with dielectric film and utilized as an anode portion of an electrolytic capacitor. In another illustrative application, the collimated hole structure is utilized as a tip for a drilling device.

摘要： A corrosion-resistant spinneret, suitable for spinning filaments of poly(p-phenylene terephthalamide) from a viscous solution of the polymer in 98-100 percent sulfuric acid, is prepared from a plate of tantalum alloy or stainless steel which is clad on one face with a layer of pure tantalum. A spinneret blank is formed, counterbores are drilled through the plate and partially into the tantalum layer, the blank is annealed, spinneret capillaries are formed from the counterbores through the tantalum layer to the exit face of the spinneret, the face is polished to remove protrusions, and the face is hardened by heat-treatment in nitrogen. Uniform capillaries having a diameter of about 0.002 inch (0.05 mm) and a length greater than about 0.005 inch (0.13 mm) can be formed in spinnerets without breaking tools used in their production.

摘要： An extrusion die for thermoplastic polymer is disclosed having a distributor which provides substantially constant residence time and pressure loss of polymer flowing through the die from the inlet to the extrusion aperture. Dies are disclosed for extrusion of sheet, film and discontinuous microfibers. The distributor has cross flow channels for conveying the polymer laterally and axially connected pressure loss and residence time control sections for independently compensating for the varying pressure loss and residence time characteristics of the polymer flow through the distribution channels. With a distributor so constructed, the overall height of the die remains substantially the same as the die width increases so that the distributor is particularly suitable for dies for wide extrusion lines.

摘要： Fibers that are formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density are provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. Fibers are thereafter formed and then stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”).

摘要： A processing system for producing starch based expanded products useful as packing material for shipping, packaging and insulating applications. In a first step, dense pellets or granules are formed from starch and a plasticizing agent such as polyvinyl alcohol. The starch in the pellets is generally formed, for example with an extruder, into a thermoplastic or thermosetting form for further processing. The pellets generally have an individual density of at least about 70 lbs./cubic foot and a small size for convenient delivery for the second processing step. The second process step is based on the expanding of the material from an extruder with water and using a dwell time. The process is designed such that a less expensive single screw extruder is suitable for extruding the expanded material. The starch based pellets are convenient for shipping closer to the end use location.

摘要： The machine includes an extrusion head having flow ducts, the inlet orifices of which are connected to the outlets of at least two extruders for supplying extruded strips made of elastomeric compounds. The outlet orifices lead into a die which is adjacent to a roller and is designed to cooperate with the latter to shape the profiled element strip. The roller has a central axis surrounded by an external surface intended to receive the profiled element strip and a means for driving the roller in rotation about its central axis. The flow ducts are mutually parallel and are perpendicular to the circumferential direction of the roller, and the profiled element strip is joined to the receiving surface of the roller along an equivalent length of at least 700 mm.

摘要： There is provided a die plate, a resin machine, and a method of heating nozzles of the die plate that can suppress temperature unevenness of the nozzles and increase the temperature rise performance of the nozzles. The die plate includes a nozzle group including a plurality of nozzles through which molten resin passes, and a heating medium guidance part that guides a heating medium for heating a nozzle wall of each nozzle. The heating medium guidance part includes an inlet that receives the heating medium, an outlet that discharges the heating medium from a heating medium channel, and a guidance wall that defines a heating channel that causes the inlet and the outlet to be in communication with each other together with an outer peripheral surface of the nozzle wall of each of the plurality of nozzles.
