TRANSFER SHEET AND MOLDING METHOD USING SAME
Provided are a transfer sheet and a molding method using the same, which enable easy cleaning and continuous use of a mold even if foreign matter is present on a cavity surface of the mold. The transfer sheet is configured such that a transfer layer is formed on one surface of a base sheet, and a foreign matter trapping layer is formed on the other surface of the base sheet. The molding method includes: a placement step of placing a transfer sheet so that the foreign matter trapping layer faces one cavity surface of a pair of molds; a molding step of clamping the pair of molds, injecting a molten resin into a molding space formed by clamping, pressing the foreign matter trapping layer against the cavity surface, and molding a molded article integrated with the transfer sheet; a mold-opening step of opening the pair of molds; a peeling step of peeling off the transfer sheet from the molded article; and a removal step of removing the molded article.
Decorative molding method and decorative molding apparatus
In a decorative molding method a film having an uneven shape printed thereon and a film having a pattern printed thereon are separately supplied to a metal mold, the films are positioned separately, and a molding material is simultaneously injected into the metal mold to carry out injection molding. In a decorative molding apparatus for realizing the above method, a suction circuit for adsorbing each of the films on a film adsorption surface of the metal mold and an air blowing circuit for peeling off the films are disposed, and, after the injection molding, air blowing on each film is started separately from the start of opening of the metal mold, and the metal mold and the films are brought into a positive pressure state, then the molded article is taken out, a clamp jig is released to release the films, and the air blowing continues until the following patterns of the films are placed inside the metal mold.
In-mould labelling process
There is disclosed an in-mould labelling process for the manufacture of a labelled article comprising the steps of: feeding a labelstock web into a mould; forming an article in the mould such that the formed article contacts and effectively adheres to a label of the labelstock web; detaching the adhered label from the labelstock web; and removing the formed and labelled article from the mould.
INJECTION-MOULDING METHOD FOR CREATING VIRTUAL THREE-DIMENSIONAL PATTERNS IN MOULDED BODIES
The present invention relates to a process for the generation of virtual three-dimensional patterns in mouldings, in particular to a reactive injection-moulding process for the production of mouldings having a virtual three-dimensional pattern which is formed by flake-form effect pigments, to the mouldings produced by means of this process, and to the use thereof, in particular for decorative purposes.
METHOD OF MANUFACTURING IN-MOLD DECORATIVE MOLDED PRODUCT
A method of manufacturing an in-mold decorative molded product including a transfer layer formed on a surface of an injection-molded product, the method including: inserting in a first mold for injection molding an in-mold transfer film including the transfer layer disposed on a base film; forming a molding injection space by mold clamping of the first mold and a second mold including a structure for injecting a resin into the molding injection space and a structure for holding a molded product; and forming a molded product by filling the molding injection space with a molding resin and then opening the second mold and the first mold, wherein when the base film is separated from the in-mold decorative molded product integrated with and the transfer layer by opening the molds, a peeling weight varies depending on a portion in an end part of the in-mold decorative molded product so that a peeling starting point is generated from a position with a light peeling weight in the in-mold transfer film to peel the in-mold decorative molded product from the in-mold transfer film.
Resin-molded electronic device with disconnect prevention
An electronic device includes an electronic component having electrodes, a resin molded body embedding the electronic component such that the electrodes are exposed, a resin member interposed between the resin molded body and the electronic component and exposed from the resin molded body, and wires formed on the resin molded body and the resin member and respectively connected to the electrodes. A thermal expansion coefficient of the resin member is lower than a thermal expansion coefficient of the resin molded body and is higher than a thermal expansion coefficient of the electrodes.
POLYORGANOSILSESQUIOXANE, TRANSFER FILM, IN-MOLD MOLDED ARTICLE, AND HARD COAT FILM
An object of the present invention is to provide a polyorganosilsesquioxane that can form a hard coat layer having high surface hardness through in-mold injection molding and can form a tack-free coating film, and thus is suitable as a material for a hard coat layer of a transfer film that can be wound as a roll. The present invention relates to a polyorganosilsesquioxane having a constituent unit represented by Formula (1) below; wherein a molar ratio of a constituent unit represented by Formula (I) below to a constituent unit represented by Formula (II) below, namely [(constituent unit represented by Formula (I))/(constituent units represented by Formula (II))], is from 20 to 500; a ratio of constituent units represented by Formula (1) below and constituent units represented by Formula (4) below relative to a total amount (100 mol %) of siloxane constituent units is from 55 to 100 mol %; a number average molecular weight is from 2500 to 50000; and a molecular weight dispersity (weight average molecular weight/number average molecular weight) is from 1.0 to 4.0; and a curable composition including the polyorganosilsesquioxane.
Multilayer body
The invention relates to a multilayer body (100) for producing a decorated plastic article (50) having a surface relief (40). The multilayer body (100) comprises a relief film (1) with a first carrier film (2) and a structural layer (3), arranged on one side of the first carrier film (2). The multilayer body (100) also comprises a multilayer film (5) with a second carrier film (10) and at least one decorative layer (12, 14). The structural layer (3) is arranged here between the first carrier film (2) and the second carrier film (10). Furthermore, the multilayer body (100) has a film body (19) which comprises the relief film (1) and can be released from the at least one decorative layer (12, 14), and the at least one decorative layer (12, 14) is formed such that it can be deformed by the structural layer (3) formed as a stamped structure. The invention also relates to a process for producing such a multilayer body (100), and to two processes for producing a decorated plastic article (50) having a surface relief (40) by using such a multilayer body (100).
Transfer film and method for manufacturing transfer film
Photocatalyst microparticles are provided in a photocatalyst layer coming into contact with a base film, the photocatalyst microparticles are irradiated with ultraviolet rays, and voids are formed in a boundary region between a protective layer and the photocatalyst layer.
TRANSFER MOLD RELEASING FILM AND METHOD FOR MANUFACTURING MATTE MOLDED BODY
A matte molded body is manufactured by forming a concavo-convex shape on a surface to be transferred of a molded body, using a transfer mold releasing film, in which a concavo-convex layer that does not include fine particles of 1 m or greater and has a transfer surface with an arithmetic average roughness Ra from 0.1 to 2 m and 60 gloss of less than 5% is formed, on at least one surface of a base layer, the concavo-convex shape being an inverted shape of the transfer surface. The concavo-convex layer may be a cured product of a curable composition including one or more polymer components and one or more curable resin precursor components. At least two components selected from the polymer components and the curable resin precursor components may be phase-separable by wet spinodal decomposition. A haze of the transfer mold releasing film may be 50% or greater. The matte molded body may be an electromagnetic wave shield film. After the concavo-convex shape is transferred using the transfer mold releasing film, the matte molded body having low gloss can be manufactured.
