The present disclosure provides a metal resin composite. The metal resin composite includes a metal substrate. The upper surface of the metal substrate is provided with at least one upper surface slit, the lower surface of the metal substrate is provided with at least one lower surface groove in a position corresponding to the upper surface slit, and the upper surface slit is connected with the lower surface groove. A first injection molding resin is formed in the upper surface slit by injection molding, and a second injection molding resin is formed in the lower surface groove by injection molding. The present disclosure also provides a preparation method of the metal resin composite, a personal electronic device shell including the metal resin composite, a personal electronic device, and a metal resin composite processing component.

First and second constituting components are injection-molded and joined within one pair of molds. In order to join the first and second constituting components, one of the respective regions of the first and second constituting components abutted to each other is pushed into the other.

A rotor includes a yoke that is formed annularly and a resin magnet integrated with the yoke. The yoke includes a first inner circumferential surface, a second inner circumferential surface, and a third inner circumferential surface. The second inner circumferential surface is adjacent to the first inner circumferential surface, and has a radius larger than a radius of the first inner circumferential surface. The third inner circumferential surface is adjacent to the second inner circumferential surface, and has a radius larger than both of the radius of the first inner circumferential surface and the radius of the second inner circumferential surface.

A film material insert molding method, includes an intermediate part forming step of forming a first intermediate part having an edge extending radially outward, the edge being disposed at and near an outer peripheral end of a final shape of a film material, a transparent resin layer forming step of forming a second intermediate part including a transparent resin layer, by injection molding, on a front surface of the first intermediate part, with the edge of the first intermediate part being fixed, and a substrate resin layer forming step of forming an insert-molded article including a substrate resin layer, by injection molding, on a back surface of the second intermediate part, the substrate resin layer covering a surface of a radially outer end of the edge.

An injection molding method includes providing a molding device including a first mold, a second mold over the first mold and a first mold cavity defined by the first mold and the second mold; injecting a first material into the first mold cavity; forming a first layer from the first material; replacing the second mold by a third mold; injecting a second material into a second mold cavity defined by the first mold and the third mold; and forming a second layer from the second material disposed over the first layer, wherein the first material is different from the second material.

The present invention comprises: a base layer molding step that injection-fills a mold cavity with a base layer resin to mold a base layer; a first expansion step that causes the volume of the mold cavity to expand to a specified quantity such that a certain space is formed between an outer surface of the base layer molded by the base layer molding step and an inner surface of the mold; a first injection-filling step that injection-fills the space formed by the first expansion step with a first resin; a second expansion step that, after the start of the first injection-filling step, causes the mold cavity to expand to a specified quantity such that the space is expanded; and a second injection-filling step that, after completion of the first injection-filling step and after the start of the second expansion step, injection-fills a second resin into the first resin.

Provided is a vehicle interior material comprising coating layers formed on both surfaces of a veneer layer; a back layer on the coating layer of one surface of the veneer layer; and a front layer on the coating layer of the other surface of the veneer layer. Provided is a method of manufacturing a vehicle interior material comprising steps of: providing a veneer layer; forming coating layers on both surfaces of the veneer layer by applying and drying water-dispersible polyurethane dispersion or water-dispersible acrylic polyurethane dispersion on the both surfaces; pre-forming a real wood film layer prepared by forming the coating layers on the both surfaces of the veneer layer; forming a back layer on the coating layer of one surface of the veneer layer by primary insert molding; and forming a front layer on the coating layer of the other surface of the veneer layer by secondary insert molding.

The present invention provides a method for efficiently manufacturing a molded foam product having excellent heat insulation, and a molded foam product obtained by such a method. The method of the present invention is a method for manufacturing a molded foam product, including the steps of: melting a resin composition containing a polyolefin and a polylactic acid and impregnating the resin composition with a fluid in a supercritical state to prepare a molten resin, and injecting the molten resin into a cavity formed in a mold and moving a portion of the mold to increase the volume of the cavity before the molten resin injected into the cavity completely solidifies, the fluid impregnated into the resin composition being a fluid of 0.05 to 4.0 wt % inert gas, the molded foam product at least partially having a five-layer cross-sectional structure of a first unfoamed layer, a first foamed layer, a hollow space, a second foamed layer, and a second unfoamed layer included in the given order.
