A method for producing a hybrid component may include placing a metallic insert part into an injection mould, at least one of over-moulding and back-injecting the metallic insert part with a plastic mass, and pretreating a surface of the metallic insert part that is to be at least one of over-moulded and back-injected prior to the at least one of over-moulding and back-injecting. The metallic insert part may be placed into the injection mould such that the metallic insert part protrudes from the plastic mass on at least one side. A material accumulation may be disposed on a transition region from the metallic insert part to the plastic mass.

Through-holes are formed at a constant pitch along a side-edge portion of a fastener tape where a tape base fabric is covered by a waterproof layer, the through-holes piercing the fastener tape. Plasma treatment or corona treatment is applied to the side-edge portion of the fastener tape so as to form an activation region on a surface of the waterproof layer on one or both sides of the fastener tape. Injection molding of fastener elements is performed to attach the fastener elements to the side-edge portion of the fastener tape. Melted resin adheres to the activation region and fills the through-hole before solidifying into the fastener element.

A method of manufacturing a tinted metal plated substrate includes injection molding a tinted polymer layer onto an activated metal layer of a metal plated substrate. The tinted polymer layer is a tinted polyurethane layer or a tinted polyurea layer and the activated metal layer can be a plasma activated metal layer, for example, an oxygen plasma activated metal layer that is free of a coupling agent when the tinted polymer layer is injected molded thereon. At least one additional metallic layer can be disposed between the activated metal layer and a polymer substrate. For example, at least one of a nickel layer and a copper layer can be disposed between an activated chromium layer and a polymer substrate.

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 method of making an iridescent, vehicular trim assembly is provided that includes: molding a polymeric base comprising an exterior surface; and over-molding an element over at least a portion of the exterior surface. The element comprises a polymeric, translucent material and an exterior surface with an integral diffraction grating having a thickness from 250 to 1000 nm and a period from 50 nanometers to 5 microns. Further, the molding can be conducted such that the polymeric base is molded with a tint. The method can also include forming a plated region over the exterior surface of the base. In addition, the method can also include cleaning the plated region with a plasma-etching process before the over-molding.

A method of manufacturing a display device, the method including ejecting a window raw material into a mold, precuring the ejected window raw material, molding a cover window by placing the precured window raw material onto a display panel and curing the precured window raw material, and separating the mold from the cover window.

Reinforced composite structural members and methods of forming thereof. The method includes providing one or more reinforcements, one or more adhesives, a mold with a mold cavity and resin. The one or more reinforcements are coated with the one or more adhesives and then are placed within the mold cavity. Next the mold cavity is closed and a step of overmolding the one or more reinforcements by injecting molten resin into the mold cavity, then curing the molten resin to form the structural member. The one or more adhesives coated onto the one or more reinforcements facilitates the bonding of the resin of material to the one or more reinforcements.

The element comprises a polymeric, translucent material and an exterior surface with an integral diffraction grating having a thickness from 250 to 1000 nm and a period from 50 nanometers to 5 microns. Further, the molding can be conducted such that the polymeric base is molded with a tint. The method can also include forming a plated region over the exterior surface of the base. In addition, the method can also include cleaning the plated region with a plasma-etching process before the over-molding.

To provide a method for manufacturing a composite member including an aluminum die cast member and a polymer member firmly bonded by removing a carbide film on the surface of the aluminum die cast member to even the surface layer. The method includes: a melting step of melting a surface layer of a joint surface of the aluminum die cast member by irradiating the joint surface with a laser, the joint surface being joined with the polymer member; and a combining step of integrally molding a polymeric material on the joint surface. The method may have a removal step of removing the carbide film present on the joint surface by irradiating the joint surface with the laser before the melting step, and a modification step of irradiating the joint surface with plasma to impart a hydroxyl group to the joint surface after the melting step.
