Interior materials are attached to an outer surface of a plastic injection mold and expose, to outside, light selectively emitted from a light source arranged in the plastic injection mold. The interior materials include a wood pattern layer formed of natural wood and having a plurality of first lighting holes through which the light passes, a light block layer coupled to a rear surface of the wood pattern layer, blocking light, and having a plurality of second lighting holes formed therein corresponding to the plurality of first lighting holes, and a touch sensor electrode coupled to a rear surface of the light block layer. As texture of natural wood is embodied on the surface of the interior materials, and the surface of interior materials emits light and simultaneously, an operation of a preset function in the interior materials may be controlled by touching the surface of interior materials.

Various embodiments disclose an electronic device comprising a housing, said housing comprising: at least one metallic material portion; and a synthetic resin material portion, said synthetic resin material comprising a sealing resin, the synthetic resin material portion joined and injection molded to at least a part of the at least one metallic material portion, wherein the sealing resin is disposed at at least a portion of a joint between the metallic material portion and the synthetic resin material portion.

The invention relates to a method for producing an injection-molded part, the injection-molded part being a plastic cylinder for a needle-free syringe. The cylinder has an opening. The invention further relates to an injection-molding tool for producing the cylinder, the injection molded tool including an outer mold component and an inner mold component, which together define a clearance which determine the injection-molded part and the cylinder. The outer mold component and the inner mold component are designed such that the clearance is formed without an obstacle for plastic between the outer mold component and the inner mold component.

A seamless lens cover, and methods of forming such a seamless lens cover. The cap structure that covers a camera of a rotating panoramic camera system includes a seamless lens cover through which images are obtained by the camera. The cap structure may be injection molded at an initial lens cover thickness, and then a portion of the as molded initial lens cover thickness may be removed (e.g., by machining away) to achieve the final desired thickness. By such a method, the lens cover may be injection molded at thicknesses suitable for injection molding (e.g., about 0.06 to about 0.1 inch), after which most of the thickness may be machined away, to provide a seamless lens cover having a thickness of less than about 0.015 inch, exhibiting at least 60% transmittance to the thermal spectrum, no lensing characteristics, and no curvature effect.

A hybrid component has at least two component portions, which are connected via at least one connection portion. The at least one connection portion extends in a joining direction. A first component portion is formed from a first material which has a first modulus of elasticity, and a second component portion is formed from a second material which has a second modulus of elasticity different from the first modulus of elasticity. The at least one connection portion is designed at least to compensate for a sudden change in rigidity between the two component portions. The at least one connection portion has a rigidity that increases in the joining direction and in the direction of the component portion with the higher modulus of elasticity.

A molding device includes a mold, having a mold cavity; a feeding port extending into the mold; a passage coupled to the feeding port and communicable with the mold cavity; and an opening coupled to the passage and communicable with the mold cavity, wherein the feeding port is disposed above the mold cavity, and the opening the disposed at a side of the mold cavity.

An inner band used on a turbine engine is disclosed herein. The inner band may include a core comprising polymeric materials and a shell comprising nanocrystalline metallic materials applied to the core to cover at least a portion of the core.

Various examples provide a mold including a molding component and a supplementary component. The molding component may have a cavity, to enable a molten material to fill into the molding component to form an object. The supplementary component may include a bypass having a first opening located at a first position of the molding component and a second opening located at a second position of the molding component. The molten material may flow from the first position to the second position via the molding component, flow from the first opening to the second opening via the bypass and fill into the second position of the molding component through the second opening.

In a plastic nut for a ball screw formed by injection molding fiber reinforced plastic, the reduction in precision over time due to wear is minimized. A thread groove is ground until the fibers in matrix plastic are exposed on the surface of the thread groove.

A rectal catheter plastic component is a constituent part of a rectal catheter assembly. The one piece plastic component has a cylindrical main body with an outer jacket wall. A connector component end serves for the attachment of a peripheral hose. A free component end serves for rectal insertion. At least one media lumen, extending along the main body, is arranged between at least one media connector port and at least one media opening. The media connector port is located at the connector component end, and the media opening is configured in the free component end. A further balloon-filling lumen, extending along the main body, extends between a filling connector port and a balloon-filling opening. The filling connector port is located at the connector component end, and the balloon-filling opening is configured in a balloon attachment region of the plastic component for the attachment of a balloon cuff.
