An imaging lens assembly includes a dual molded optical element, a plurality of imaging lens elements and a light blocking element. The dual molded optical element has an object-side surface and an image-side surface and includes a light transmitting portion and a light absorbing portion. The light transmitting portion includes an optical effective section. The light absorbing portion is located on at least one of the object-side surface and the image-side surface of the dual molded optical element, and a plastic material of the light absorbing portion and a plastic material of the light transmitting portion are different colors. The imaging lens elements are disposed in the inner space of the imaging lens assembly. The light blocking element is disposed adjacent to the light transmitting portion of the dual molded optical element.

A molding unit has a first molding station having a first mold having a first mold cavity, a second molding station having a second mold having a second mold cavity, a transfer unit having a support and at least a first core extending from the support. The transfer unit is arranged for moving the first core into a first molding position at the first molding station and into a second molding position at the second molding station. The first core extends into the first mold cavity when the first core is in the first molding position and into the second mold cavity when the first core is in the second molding position. A core actuation unit is arranged so that at least at the first molding station the first core is moved relative to the support from a first core position into a second core position when the first core is moved into the first molding position.

There is provided a liquid supply member capable of suppressing deformation of a liquid supply path and decrease in sealing property of a liquid supply path, during molding, and a manufacturing method of the liquid supply member. For that purpose, in die-slide injection molding that combines two components, a protection portion that protects a part of one component easily affected by heat and pressure, is provided on the other component.

A method for producing a vehicle rear module that includes: a clear member monolithically including a lamp section and a window section; and a colored member for shielding at least part of a vehicle interior from the exterior. The method for producing the vehicle rear module comprises: a step for injecting a transparent resin from a single resin injection hole into a first cavity to form the clear member; and a step for injecting a colored resin from a plurality of resin injection holes into a second cavity to form the colored member.

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

A method of manufacturing a real material product having a composite layer and using a liquid-phase reactive curing method according to the present invention can precisely and beautifully manufacture a real material product through a double injection process, and can implement various patterns. The bottom of a real material layer is coated with a plastic resin layer, and the top of the real material layer is coated with a PUA or PUR layer.

A sealing member, that is a resin molded product to be joined to a flow path forming member through which a fluid flows, has a surface including an opening constituting or including a portion of the flow path, a protrusion surrounding the circumference of the opening and a rib having one of its opposite ends connected to a part of the protrusion and the other end located inside or outside of the protrusion. The protrusion has at the top thereof a contact region to be pressed against and held in contact with the flow path forming member.

A resin fan includes a semi-molded article in which a first circular plate and blades are integrated. While the semi-molded article is retained, a composite mold is moved to a secondary molding side, a second mold is put in a first position and a third mold is moved to the first position and inserted into the first mold. An intermediate part extends over the inner surface-side of a large-bend part, and causes the end of the third mold to engage with the first mold. Next, resin is poured into a secondary forming mold, and a second circular plate is integrally molded continuous with the blades of the semi-molded article, and a fan is molded. Together with the opening of the second mold and the composite mold, the third mold and the composite mold are opened, each of the molds is moved to a second position.

A method of manufacturing a liquid ejection head including a first step of having a molten resin becoming a first portion flow in between a first position in a first mold and a first position in a second mold and the molten resin becoming a second portion flow in between a second position in the first mold and a second position in the second mold; a second step of relatively moving the first and second molds, after opening the molds; a third step of closing the molds; a fourth step of joining the first and second portions, a fifth step of taking out the first and second portions and the sealing portion from the molds and mounting a recording element substrate; and a step of forming a space portion between a liquid supply path surface and a mounting surface.
