A manufacturing method for manufacturing a pipe joint including a circular tube-shaped housing and an elastically deformable circular tube-shaped seal member provided at an inner peripheral side of the housing. The pipe joint manufacturing method includes a process of placing the seal member inside a mold in a state in which the seal member is fitted to an outer periphery of a retaining pin, and a process of causing a molten resin to flow into the mold so as to mold the housing in a state in which the seal member is cooled through the retaining pin.

The present invention relates to a multi-component gear (1) with an axis of rotation (X) and a first end face (11) and a second end face (12), having an inner part (20) and an outer part (30) made of a plastic with at least one injection-molding section (32), wherein the outer part (30) is arranged on an outer lateral surface (24) of the inner part (20) in a form-fitting and/or integral manner on the inner part (20), and wherein the outer part (30) on the first and/or the second end face (11, 12) has at least one tab (40) which is free-standing in the circumferential direction around the axis of rotation (X) and which protrudes over the relevant end face (11, 12) of the inner part (20). The present invention also relates to a gear (2) and a planetary gearset (3).

An injector for introducing a fluid includes a main body designed as an insert and including a first tool contact surface for an injection-molding tool and a second tool contact surface for the injection-molding tool; and an injection-molded housing that completely encloses the main body on at least one portion of the main body, the injection-molded housing including at least one first opening that extends linearly towards the main body.

Thermoplastic synthetic resin flowing through both gates 173, 173 into lug part flanges 16, 16 collides with a confronting wall 161, converts direction of flow by 90°, changing velocity of flow, and thus fills the lug part flanges 16, 16 and flanges 15,15 on the long side. After this, as thermoplastic synthetic resin flows into thin outer peripheral walls 131, 132 and partition walls 133 at an optimum velocity of flow, thermoplastic synthetic resin flows smoothly and it is possible to form a smooth molded article. The lug part flanges 16,16 and the flanges 15, 15 on the long side serve as runners, so that thermoplastic synthetic resin flows smoothly into the thin outer peripheral walls 131,132 and partition wall 133.

A process for manufacturing a watch dial including at least one pattern on a visible face of the dial, the process including: a step of designing a support plate including a dial blank, this step including producing several through holes in the thickness of the body of a support plate, the holes delimiting in such a plate the edge of the dial blank, and a step of producing at least one pattern on a visible face of the dial blank during which step the following is performed: an arrangement of this support plate including the external part element in a mould, and a construction of a blank of each pattern on the visible face of the dial blank, as well as a finalisation of the blank of the pattern.

A system for producing at least one three-dimensional element on a visible face of an external part element of a timepiece implementing this process, the system including a mould formed by the reversible assembly of a first part and a second part configured to receive a support plate of the external part element, the mould including at least one cavity formed by associating the first part including at least one impression with the visible face of the external part element, each cavity helping produce a blank of the three-dimensional element from an over-moulding by injecting injectable material onto the visible face, and a device for applying a coating onto the blank over-moulded on the visible face of the external part element helping finalise this blank of the three-dimensional element.

A plug-in connector produced by injection molding a plastic material and having an internal channel for a fluid and having three main sections situated axially one behind the other. The plug-in connector has a gate point on its outer circumference solely on one side and a mass distribution of the plastic material that is radially asymmetrical with respect to the circumference and which is present in at least one of the main sections of the shaped part. A method for the production of the plug-in connector is likewise disclosed.

Provided is a resin molded article which makes it possible to prevent breakage of a resin and collar loss at joint sections. A resin molded article (1) is formed by resin injection, and comprises a main body (2) and a joint section (3) integrally formed at an outer wall surface (4) of the main body (2) and having a cylindrical section (11) configured to insert therethrough the joint member for attaching the main body (2) to a mating member (6). The joint section (3) is formed to be asymmetric about a perpendicular plane (19) which passes through the central axis (18) of the cylindrical sections (11), and is perpendicular to the outer wall surface (4) of the main body (2).

A molding method for a synthetic resin molding reduces a disturbed flow of molten resin at a side edge of a molding body during injection molding, and allows the design surface of the molding body to have aesthetic appearance. The synthetic resin molding includes a bend arranged on a side edge of the molding body and bending toward its back surface, and a flange protruding laterally from the bend and including a notch. The molding method includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction and performing injection molding using a colored resin material containing a luster agent kneaded in the material, and forming a thin portion of the bend in a longitudinal direction of the bend to form a groove on a back surface of the bend.

A pipe connection comprises a connecting piece, a pipe and a clamping ring. The pipe and the clamping ring are made of a material having memory properties. An end of the pipe and the clamping ring have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece by back shrinkage. Preferably the clamping ring is made from a cross-linked polyolefin by injection molding.
