A method of manufacturing a clad metal casing includes the steps of arranging and connecting metallic materials with different types from each other to form a clad board; shaping the clad board; and post-process the appearance surface of the formed clad board to form the clad metal casing. The appearance surface after the post-process presents surfaces of at least two metallic materials.

A magnesium alloy/resin composite structure including a magnesium alloy member and a resin member integrated to the magnesium alloy member and made of a thermoplastic resin composition, in which the magnesium alloy member surface to which the resin member is not integrated is coated with a layer including a manganese atom, an oxygen atom, and a sulfur atom.

A manufacturing method of a housing includes the following steps: a preformed housing is provided. The preformed housing includes a body and a sidewall connected to the edge of the body, and a decoration film disposed on the body and the sidewall. A portion of the sidewall is exposed from the decoration film. The body includes a first surface. The sidewall includes a second surface. The second surface extends from the first surface. The first surface and the second surface are non-coplanar. A decoration layer is formed on the exposed portion of the sidewall by a surface processing treatment.

Provided are an assembly type terminal for a fuel pump capable of decreasing a process additionally required at the time of injection-molding a flange using a separation type terminal according to the related art and preventing a defect of a product that may occur at the time of injection-molding the flange, and a method of manufacturing a fuel pump flange using the same. The assembly type terminal for a fuel pump includes: a plurality of power supply terminals; a plurality of coupling bodies 100 and 200 coupling one or more power supply terminals to each other; and a coupling member 300 formed in the coupling bodies and coupling the plurality of coupling bodies 100 and 200 to each other, wherein the plurality of coupling bodies are spaced apart from each other and are coupled to each other by the coupling member.

Techniques for overmolding thermoplastics onto a spray primed polymer substrate. A thin layer of primer may be sprayed directly over a pre-formed polymer material. Then, a thermoplastic is injection molded directly over the primer layer. In one embodiment, a carbon fiber-reinforced polymer (CFRP) fabric is thermal compression molded into a NED device housing shell. Selected portions of the NED device housing shell may be mechanically abraded and then sprayed with a solvent-based polyolefin primer. Once the primer layer has cured, a thermoplastic material may then be overmolded directly over the primer layerwithout any additional adhesive layer(s) between the primer layer and the thermoplastic material.

Curable compositions, such as by way of exposure to radiation in the electromagnetic spectrum, for use as a primer composition for injection molding applications, are provided.

A ceramic and plastic composite and a method for fabricating the same are disclosed. A chemical cleaning treatment, a microetching treatment, a hole reaming treatment, and a surface activating treatment are performed on the surface of a ceramic matrix to form nanoholes with an average diameter ranging between 150 nm and 450 nm. Plastics are injected onto the surface of the baked ceramic matrix to form a plastic layer. The plastic layer more deeply fills the nanoholes to have higher adhesion. Thus, the higher combined strength and air tightness exist between the ceramic matrix and the plastic layer to improve the reliability and the using performance of the ceramic and plastic composite.

A cover of a fuel supply module is adapted to disable a flow path through a designated port. An element is press-fit into the designated port to plug the designated port, and thermoplastic material is molded over an interface defined between the element and the designated port.

This specification discloses an article of manufacture. The article of manufacture has at least one structural blank and at least one guide. The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

The present disclosure provides a metal-resin composite and a preparation method. The metal-resin composite includes a metal substrate; a porous resin layer formed on the metal substrate; a plastic layer formed on the porous resin layer; and a pore passage. The pore passage passes through the porous resin layer and extends inside the metal substrate, and the plastic layer fills in the pore passage to bond with the metal substrate.
