Abstract:
The present invention relates to a method of injection-moulding electrically shielding electronic casings, where a laminate (3) that comprises at least one metal foil (9) and at least one plastic layer (8) is held stretched in an injection-moulding tool. According to the invention, a plastic structure is moulded in the tool on that side of the laminate (3) which comprises the plastic layer (8), wherewith the laminate (3) is deep-drawn in the tool and formed therein as the plastic material is injected thereinto and the plastic layer adheres to the plastic structure, therewith forming a moulded plastic element which includes an integrated and uniformly distributed and therewith shielding metal layer.
Abstract:
A method for manufacturing optical and microwave reflectors includes: placing an assembly comprising a resin-infiltrated tendrillar mat structure (130) on a mandrel (110); placing a pre-impregnated carbon fiber (CF) lamina (140) on top of the tendrillar mat structure (130); placing the assembly in a vacuum device so as to squeeze out excess resin; and placing the assembly in a heating device so as to cure the tendrillar mat structure together with the CF lamina, forming the CF laminae into a laminate that combines with the tendrillar mat structure to create a cured assembly. A reflector suitable for one or more of optical and microwave applications includes: a mandrel (110); a resin-infiltrated tendrillar mat structure (130) placed on the mandrel (110); and a pre-impregnated carbon fiber (CF) lamina (140) placed on top of the tendrillar mat structure (130).

Abstract:
The invention relates to a method for manufacturing a housing part with screening functions and a housing part with screening functions for a radiocommunication equipment having saucer-type housing parts with overlying, facing open sides to lodge the radiocommunications device. To shorten the manufacturing process by one step, a wire web which has been cut according to the inner contours of the housing part is introduced in an injection mould for the screening housing part. In said wire web, all contact surfaces and their counterparts are coated with a foil corresponding to the dimensions of the desired contact surface. The foils are removed after subsequent injection moulding with insulating material.

Abstract:
The invention concerns a manufacturing method of a new type of dielectric material having a predefined variable permittivity resulting from the manufacturing process. Main characteristic of the manufacturing method is that in a first step homogeneous dielectric material (100) is shaped in at least a direction and subsequently at least a part thereof is formed so that the resulting dielectric material body (102) has the predefined variation in permittivity in said at least one direction. Said forming step may advantageously comprise sub- steps of deforming at least a part of the shaped dielectric material body and fixing the so deformed dielectric material body. The manufacturing steps are adapted so to induce a predefined variation in permittivity corresponding but not limited to a certain law (e.g. Luneburg, Maxwell,...). The invention further concerns a manufacturing method of an electromagnetic lens that can be used in a millimeter-waves multi-beam forming antenna system where said electromagnetic lens is composed of the new type of dielectric material.
