A manufacturing method for a trim element, which includes the following steps: supplying a mold in an open configuration which has a first mold part and a second mold part; positioning a first pre-formed decoration against the first mold part; positioning a wedge in contact with an edge of the first decoration; positioning a second flexible décor; closing the mold in a closed configuration, where the second decoration sits between the two mold parts; and back-injecting a substrate into the molding cavity, where the second decoration is pushed by the substrate against the first decoration. Also provided is an associated manufacturing device.

An electrical assembly may include an electrically conductive first member, a magnetic second member, and/or a housing molded on the first member and the second member. A method of assembling an electrical assembly may include disposing the first member in contact with a first mold, disposing the second member in contact with the first mold, moving a second mold into contact with the first mold, and/or inserting a housing material (e.g., liquid plastic) into the first mold and the second mold to form the housing.

An injection molding method for a product with a connection elastic sheet, a loudspeaker and an electronic device are provided. The method comprises: providing a blank material comprising at least one connection piece and a material connection strip, and each connection piece comprising an elastic arm portion and a wire portion; positioning the blank material as an insert in a first injection mold by means of the material connection strip; injecting a first injection plastic part into the first injection cavity to obtain a first injection product; processing the first injection product for bending up the elastic arm portion toward an outer surface of the first injection plastic part; placing the processed first injection product into a second injection cavity of a second injection mold, and sealing the elastic arm portion; and injecting a second injection plastic part into the second injection cavity.

According to an embodiment of the present disclosure, provided is a method for manufacturing a bus bar in which a frame including a sensing part and a body part connected to the sensing part is prepared, the frame is inserted into and fixed to an injection molding mold, and an enhanced part enhancing the strength at a position where fatigue is concentrated by an enhancing injection material injected into the injection molding mold is formed in the frame.

Performed are an accommodation step of accommodating a pair of conductive members in a die, a sealing step of injecting a resin to seal the conductive members, and an extraction step of extracting a conductive member module. In the sealing step, the conductive members are sealed while a force is applied by the resin injected into the die to the individual conductive members in directions away from each other, and the individual conductive members are supported by support members disposed outside.

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.

A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the accommodation step, the two individual conductive members are sandwiched in the facing orientation thereof by outer support members abutting outer surfaces of the conductive members, and inner support members abutting inner surfaces of the conductive members. Outer recesses are formed in the outer surfaces by the outer support members, and inner recesses are formed in the inner surfaces by the inner support members. The outer recesses are deeper in the Z direction than the inner recesses.

A battery pack according to an embodiment of the present disclosure includes a plurality of battery cells, and a pack case in which the plurality of battery cells are accommodated, wherein the pack case includes a potting resin which covers all sides of the plurality of battery cells and is filled to a predetermined height between the plurality of battery cells.

An injection molding one-piece cutting board (2) comprises two pre-molding wear-resistant chopping plates (21) spaced apart from each other in parallel. Two holding holes (211) of the two chopping plates (21) are respectively press-fitted at an upper side and a lower side of a positioning block (31) arranged inside an injection molding mold (3). Two open groove portions (32) of the mold (3) are respectively arranged corresponding to an upper side of one chopping plate (21) and a lower side of the other chopping plate (21). A cover groove portion (33) of the mold (3) is surrounded the peripherals of the two chopping plates (21). A plastic material is injected into a space defined between the two chopping plates (21) and then filled with the plastic material to form a middle thickness support (22) and the cover groove portion (33) to form a frame (23).

The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.
