There is provided a manufacturing method for molding a liquid supply member by using a first mold and a second mold. The method includes a first molding step of performing injection molding to form a first component part of the liquid supply member and a plurality of component parts of the liquid supply member other than the first component part at different positions from each other, with the first and the second mold closed relative to each other, a contacting step of moving each of the formed plurality of component parts relatively to the first component part to bring the formed first component part into contact with the formed plurality of component parts, with the first and the second mold opened relative to each other, and a second molding step of performing injection molding to join the first component part and the plurality of component parts.

The present teachings generally relate to a flexible, structural carrier for reinforcement of hollow tubes, cavities, and the like. The structural carrier comprises two or more reinforcing member segments; a foamable material disposed along a portion of the two or more reinforcing member segments; and at least one insert that connects the two or more reinforcing member segments in a manner that enables flexible movement of the segments relative to each other. The carrier is adapted for the structural reinforcement of a hollow tube or cavity featuring complex curvatures.

The invention is directed to an overmolded two-component friction element in a plastic pallet and to a method for forming the pallet. The friction element includes a rigid outer carrier member and an elastomeric material that is exposed at one or more ends. The friction element is first formed in an injection mold, and then is placed in a pallet mold. Resin is injected into the pallet mold around the sides of the friction element leaving the exposed elastomeric material form part of the pallet surface.

A method for producing a thermoplastic container (1) for gases or liquids. First, in an injection mould having a first (28) and a second mould (29), in a first position providing each a cavity (34) for an upper (2) and a lower shell (3), producing the shells in parallel. Next, opening the mould, the shells (2, 3) remaining in a respective mould. Then, turning or shifting at least one of the two moulds such that the concave interior sides of the shells are aligned against each other and closing the mould, so that the edge regions (7, 8) of the shells come into face-to-face contact. Injection material is injected into a cavity (49) between or adjacent to the edge areas (7, 8), forming an all-round welded seam (11) between the upper part (2) and the lower part (3). Finally the mould is opened and the at least one container is removed.

Provided in this disclosure is a method for manufacturing a customizable holster. Steps are provided of molding inner holster components, including molding internal surfaces that conform to shapes of respective portions of a desired firearm design. Other substeps include molding external surfaces that conform to the shape of portions of an external mating surface of an inner holster. The inner holster components are mated to form an inner holster having an internal contact surface that conforms to the firearm design, to securely receive and retain a respective firearm within the inner holster. An outer holster is molded having an interior defined by an internal mating surface that conforms with the external mating surface of the inner holster. The inner holster is then mated to the outer holster such that the external mating surface of the inner holster is received within the internal mating surface of the outer holster.

The present invention provides a method for producing molded articles by joining primary molded parts by injection welding, by which a molded article composed of primary molded parts that are joined with high weld strength can be produced. The present invention relates to a method for producing molded articles including a welding step of injecting an injection welding material containing a polyamide around or between butt weld portions of primary molded parts disposed in face-to-face contact, so as to weld the primary molded parts together to form a molded article. The polyamide contains dicarboxylic acid units and diamine units. This polyamide further contains triamine units in an amount of 0.05 to 1 mol % with respect to the total dicarboxylic acid units.

A passive horn integrally formed by using liquid silicone rubber, includes a first outer casing, a second outer casing, an inner casing and an iron piece. The first outer casing includes a sealing ring, a folding ring and a vibrating membrane, and the sealing ring, the folding ring and the vibrating membrane are integrally injection molded into the first outer casing. A groove is disposed in the second outer casing, and the first outer casing is disposed in the groove. The back surface of the vibrating membrane is provided with a casing groove, which is sequentially embedded with the inner casing and the iron piece. A preparation method of a passive horn integrally formed by using liquid silicone rubber, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

In order to provide a bonded part capable of reducing deformation caused by injection pressure of bonding resin and preventing an increase in cost, the bonded part includes a first part, a second part, and a third part, wherein the first part includes a wall portion and a hollow portion surrounded by the wall portion, wherein a first shape portion formed of bonding resin is arranged at a position between the second part and the wall portion, wherein a second shape portion formed of the bonding resin is arranged at a position between the wall portion and the third part, and wherein a third shape portion formed of the bonding resin which connects the first shape portion and the second shape portion is arranged on the wall portion.
