Abstract: An extrusion-coated metal article is prepared by applying a mixture which comprises an organosilane composition to a metal surface, and then extruding a melt of a polyamide molding composition onto the coated surface thus treated and dried.

Abstract: The present invention generally is directed to compositions, products and methods that utilize superabsorbent polymers for flame-retarding. A preferred method includes improving flame-retarding characteristics in products by adding SAPs to the product. Prior to the step of adding the SAPs, the product exhibits a first limiting oxygen index and after the step of adding the SAPs, the product exhibits a second limiting oxygen index, with the second limiting oxygen index being higher than the first limiting oxygen index. Preferably, the SAPs can be pre-loaded with moisture, thereby potentially further increasing the flame-retarding characteristics of the product. In a preferred embodiment, the product is configured as a cable, with the outer jacket of the cable incorporating the SAPs.

Abstract: A pre-twisted cable pair and a method for processing such pairs into an electrical cable having improved electrical and mechanical properties is disclosed. At least one insulated wire for transmitting electrical signals is pre-twisted prior to pairing with another insulated wire. As the pre-twisted wires are paired by a conventional double-twist machine which imparts back-twist, the detrimental electrical effects caused by irregularities in the individual wires are cycled over a very short distance, resulting in a cable pair having lower structural return loss, near-end crosstalk, and insertion loss than wires paired without any pre-twist. These pre-twisted wires may be united into a jacketed electrical cable by a continuous-extrusion jacketing process in which an optimal dielectric constant is maintained around each individual cable pair.

Abstract: A producing method of a hose including, using a mold assembly constituted by a pair of semicylindrical molds each having a large number of intrusion grooves formed along the axial direction in the cylindrical surface of each of the semicylindrical molds substantially at regular intervals and supplying electrically conductive wire into the hose molding mold assembly substantially linearly along the axial direction of the mold assembly; extruding a molten resin tubularly to supply the molten resin into the mold assembly after the supply of the electrically conductive wire; supplying high-pressure air into the inside of the thus extruded molten resin tube to thereby expand the molten resin tube along the corrugated surface of the mold assembly to bring the molten resin tube into contact with the corrugated surface of the mold assembly and, at the same time, making a part of the tube go around to the outer circumferential surface side of the electrically conductive wire along the intrusion grooves of the mold ass

Abstract: A molding for automobile includes a molding body (1, 25) comprising a vertical supporting portion (2, 26) made of a synthetic resin, a decorative portion (3, 27) made from synthetic resin and integrally connected to the vertical supporting portion (2, 26), and a metal piece (5, 28) embedded in the vertical supporting portion (2, 26) and decorative portion (3, 27), wherein the metal piece (5, 28) is rigidly and integrally joined to the molding body (1, 25) via an adhesive resin layer (6, 29) of a polar group containing thermoplastic resin composition.

Abstract: In a method for working the end portion of a roof molding for use in an automobile, at desired position on the molding surface 32 of a pressing mold 31 that faces a cut-away portion 21 formed on the back surface of the end portion 12 of the roof molding, there is formed a pressing projecting portion 33 which extends along the width direction of the end portion 12. In a pressing operation after the end portion 12 is heated and softened, the cut-away portion 21 of the back surface of the end portion 12 is pressed and deformed by the pressing projecting portion 33 of the pressing mold 31 to thereby form a mounting and fixing projection portion 22 which projects toward at least one side in the width direction of the end portion 12.

Abstract: A method and apparatus for covering a roll core with a polymeric material, preferably a high performance thermoplastic material, is disclosed. The method includes first providing a cylindrical roll core having two ends, a length, and an outer surface. A spacer assembly is attached proximate one end of the roll core, the spacer assembly having a circumference greater than that of the roll core. After preheating to a desired temperature, the roll core is then placed within an apparatus in a substantially vertical orientation and held therein by suitable fixtures, e.g., opposed universal chucks. A length of mold tape is helically wound over the length of the roll core in a spaced-apart relationship therewith to define an application zone between the mold tape and the roll core outer surface. A filament formed of the polymeric material is extruded within the application zone and helically wound over the roll core outer surface so that the roll core is covered with the material.

Abstract: A method of manufacturing the molding 1 comprising a forming process of preparing a molded material 100 which is used as a core metal 10 and has a uniform sectional configuration by forming a material of the core metal 10 into a predetermined configuration; a cut-off process of cutting off a part of the molded material 100 to prepare the core metal 10 whose sectional configuration is varied; and an extrusion process of variably extruding the synthetic resin 19 onto a surface of the core metal 10 by moving a movable die 41 according to the sectional configuration of the core metal 10, using an extruding die body 40 and the movable die 41 installed on the die body 40. According to this method, the adherence of the synthetic resin to the core metal can be reliably accomplished, and thus the molding-manufacturing method having a high productivity can be provided.
