Controllability of an input amount of a filler is improved to manufacture a molded substance having higher performance. The molded substance is manufactured by using an injection molding machine including: a cylinder 11 having a supply port 13h which is located upstream and through which a resin pellet RP is supplied and a supply port 15h which is located downstream of the supply port 13h and through which a filler F is supplied; a screw S disposed inside the cylinder; and a cutting machine 15. The cutting machine 15 continuously cuts a thread-state fiber (roving R) to a constant length, and inputs cut fiber pieces (filler F) into the supply port 15h.

An electromagnetic wave shielding thin film for shielding from electromagnetic waves generated in an electronic part is provided. The electromagnetic wave shielding thin film includes metal plate which has elastic limit of 1% or more, strength of 1000 MPa or more, and a volume fraction of an amorphous phase of 50% or more.

Semi-finished product made from composite material comprising a thermoplastic or thermosetting matrix and reinforcement fillers. The semi-finished product comprises an electromagnetic shielding film positioned in the thickness of the semi-finished product, the electromagnetic shielding film comprising holes.

Thermoplastic resin foamed particles of the present invention including more than one functional additive selected from inorganic powder and inorganic fibers each includes a core layer formed of a thermoplastic resin and a coating layer in a foamed state formed of a thermoplastic resin, the mass ratio of the coating layer to the core layer is 99:1 to 50:50, the content (X) of the functional additive in the core layer is 5 to 90% by mass, and the content of the functional additive in the coating layer is smaller than the content (X) of the functional additive in the core layer. By this way, thermoplastic resin foamed particles from which a homogeneous foamed particle molding having excellent dimension stability, fusibility and appearance can be obtained while containing functional additive are provided.

The present invention achieves cost reduction by simplifying the manufacturing process for a film-formed molded product provided with a metal coating film capable of transmitting electromagnetic waves therethrough. This method for manufacturing a film-formed molded product which includes a molded product and a metal coating film covering the molded product comprises: forming the molded product between a movable mold and a fixed mold; and then forming the metal coating film which covers the molded product by a film-forming part of a second mold without taking the molded product out from between the movable mold and the fixed mold. The metal coating film is capable of transmitting electromagnetic waves therethrough as a result of generation of cracks after being formed.

The present invention relates to methods of manufacturing moulded products, for example building panels, and in particular, but not exclusively, to manufacturing a panel comprising natural stone or rock set into a polymeric layer. The method of manufacturing a moulded product as described herein comprises at least one article being set into a polymeric layer, followed by placing the at least one article and particulate ferrous material in a container so that at least a portion of the or each article is embedded in the particulate ferrous material, introducing a polymeric material into the container to form the moulded product, and removing the moulded product from the container.

A method for producing a housing component with shielding from electrical and/or magnetic radiation and with an environmental seal function, is disclosed. A metal housing part is produced by folding a metal sheet. A synthetic shaped part is produced by thermoforming such that the shape of the synthetic shaped part matches the metal housing part. The synthetic shaped part is connected to the metal housing part. A method for producing a high-voltage store, a housing component with shielding from electrical and/or magnetic radiation, and a high-voltage store are also disclosed.

An electrical member comprises a housing and an electromagnetic shielding. The electromagnetic shielding is formed at least in sections by an electrically conductive coating on the housing.

The present invention relates to an optical composition for blocking near-infrared rays, comprising a mixture of a polyurethane-based thermosetting resin composition and a near-infrared absorbent, wherein the optical composition for blocking near-infrared rays comprises (1) at least one of polyisocyanate compounds in a liquid phase (I); (2) at least one of polyol or polythiol compounds in a liquid phase (II); and (3) a near-infrared absorbent having a high near-infrared absorbing ability of less than 5% in the range of 800-1000 nm, and to a method for manufacturing near-infrared blocking spectacle lens using the same. The spectacle lens obtained from the optical composition of the present invention can effectively prevent damage to the retina by effectively blocking near-infrared rays.

Thermoplastic resin foamed particles of the present invention including more than one functional additive selected from inorganic powder and inorganic fibers each includes a core layer formed of a thermoplastic resin and a coating layer in a foamed state formed of a thermoplastic resin, the mass ratio of the coating layer to the core layer is 99:1 to 50:50, the content (X) of the functional additive in the core layer is 5 to 90% by mass, and the content of the functional additive in the coating layer is smaller than the content (X) of the functional additive in the core layer. By this way, thermoplastic resin foamed particles from which a homogeneous foamed particle molding having excellent dimension stability, fusibility and appearance can be obtained while containing functional additive are provided.
