A mounting element, i.e., a retaining element or clip, for mounting a terminal element at a component housing of a component body by extrusion-coating the component body at least in part with a coating material, which is designed (i) for holding and positioning a terminal element at a component housing of a component body while the component body is being extrusion-coated with a coating material, and (ii) for accommodating at least in part in the interior of a molding tool during the coating, (iii) which includes at least two support elements, and (iv) in which the at least two support elements are designed so that they are supported at an inner surface of the molding tool when the mounting element is held at the component housing of the component body while the component body and the mounting element are accommodated in the interior of the molding tool.

A vehicle light assembly includes a housing. A light source is positioned within the housing. A lens is coupled with the housing. The lens defines a first surface and a second surface. A plurality of optical gratings is integrally defined in at least one of the first and second surfaces. The plurality of optical gratings is arranged in a spaced apart configuration.

The present invention addresses the problem of manufacturing first and second members with different materials when molding injection molding body one after another using first to third molds disposed at 120 degrees from each other on a turntable that performs reciprocating motion at 120 degrees and using fourth to sixth molds provided opposite to the first to third molds, respectively. According to the solution, first to third injection devices are disposed on the sides of fourth to sixth molds, respectively, the first injection device is caused to perform primary injection to mold a first member, and the second and third injection devices are caused to perform primary injection to mold a second member and secondary injection to integrate the first and second members with each other, whereby the first and second members can be manufactured with different materials one after another.

A method for insert molding a product which includes providing an insert having a plurality of elements that are loosely linked together; applying a bonding agent to at least two of the elements to temporarily link those to elements in substantially locked mutually fixed relationship; supporting the at least two elements within a mold; injecting molding material within the mold whereby a molded part surrounding the at least two elements is formed; and flexing the molded part to substantially unlock the elements disposed in substantially locked mutually fixed relationship.

A plastic, internally hollow body has a cavity for containing liquid, solid or gaseous material and comprises a shaped main body and a closure body joined together by a joining element, overmolded to the main body and to the closure body. A method for producing the internally hollow body provides for joining the main body and the closure body in the same step wherein a second closure body and/or of a second main body to be used in a subsequent union step are molded to obtain a second internally hollow body. The internally hollow body is molded by means of a mold comprising punch impressions and die impressions and a movable shaped element which engages with the punch or with the die and which is movable to transfer the first main body from a main die or a punch impression to a union impression of a die or punch.

A method of manufacturing a liquid ejecting method includes: a first step of injection molding passage members collectively constituting a passage for a liquid in the liquid ejecting head; a second step of moving the passage members to bring the passage members into contact with each other; and a third step of injecting a sealing material into a space between the passage members held in contact with each other, and filling the space with the sealing material. The sealing material is injected and filled, from a gate on a longitudinal side of the passage members, in a direction intersecting with a longitudinal direction of the passage members.

A method of manufacturing a liquid ejecting head has a first molding step, a step of performing positioning and a second molding step. In the first molding step, a first member, a second member, and a third member are molded by injecting a resin at different locations inside of a set of a fixed mold, an intermediate movable mold, and a movable mold. In the step of performing positioning, the set is detached in a first direction and the intermediate movable mold and the movable mold are moved in a second direction. In the second molding step, a resin is injected to the inside of the set that is clamped to bond. During a period from the first molding step to completion of the second molding step, the first member, the second member, and the third member are held by insert mold pieces used for molding the members, respectively, in the first molding step.
