Abstract: To provide a resin molded product having a desired surface shape, a resin molding mold which can manufacture the resin molded product and a method of manufacturing the same, and a resin molding mold manufacturing system to achieve manufacturing of the resin molding mold, a resin molding mold according to the present invention includes a molding mold main body and a resin layer exposedly formed on a mold surface side of the molding mold main body, made of a heat-resistant complex material containing a synthetic resin, and a ceramic powder particle, and having a thickness of 50 to 800 ?m. The resin molding mold according to the present invention includes the molding mold main body and the resin layer exposedly formed on the mold surface side of the molding mold main body and made of the heat-resistant composite materials including a synthetic resin, and the ceramic powder particle, and recesses and projections are formed on the resin layer by excavating a portion of the resin layer.

Abstract: A molding die includes a die having a mold plane; and gloss control granules composed of 50 to 80 pbw of a shape retention fixation base material such as a thermosetting resin; 30 to 80 pbw of a diffuse reflecting surface formation core material such as a ceramic powder; and 5 to 10 pbw of a roughness enhancement material such as an inorganic fiber, adhered to the mold plane in a spaced-apart manner. The gloss control granules are each independently adhered in the spaced-apart manner to form gloss control projections on the mold plane of the die so that a surface of a molded product molded on the die forms a surface having a small specular reflection or a diffuse reflection, and the gloss control projections having fine, uneven surfaces with recesses and projections are formed on the mold plane at a coating rate of 40 to 80%.

Abstract: Provided is a mold part for resin molding and a manufacturing method. A mold part for molding resin includes a base material layer, a design section and uneven sections which abut an inner surface so as to form ventilation sections. The design section has a design surface transferred by a reverse master having an uneven surface. At least the design section out of the base material layer and the design section is formed of a heat resistant material, and the mold part for resin molding is interchangeably attached to the molding tool so that a molding pressure acts in a direction to press the uneven sections against the inner surface of the molding tool at the time of molding the resin molded article.

Abstract: [Problem to be Solved] Provided are a molding die by which a molded article with a reduced gloss can be molded; and a manufacturing method therefor, and provided are a method for matching the gloss levels of molded articles, by which the glosses of the surfaces of the molded articles molded with materials such as different synthetic resins can be matched; a molding die; and a manufacturing method therefor.

Abstract: [Summary] [Technical problem] The main object of the present invention is to provide a mold part for resin molding and manufacturing method which can easily change a design on a product surface side without requiring substantial effort and cost and diversify the selection of post-processings on this design surface and are suitably used by being attached to diverse molding tools.

Abstract: A method for forming a convex pattern on a surface of a sheet includes the steps of covering a photosensitive resin film 21 with a masking film 4 having a convex forming area 40 corresponding to a convex pattern to be obtained, exposing the photosensitive resin film 21 to light from an outside of the masking film 4, and removing an unexposed portion of the photosensitive resin film 21 subjected to the exposing step, thereby forming a sheet 2 with an exposed portion 22 left, and the convex forming area 40 of the masking film 4 has a semi-translucent portion 43 and a translucent portion 41 formed in sequence at an outside of a light-shielding portion 42 in order to express a shade in gradation, and a light transmittance increases stepwise from the light-shielding portion 42 toward the translucent portion 41.

Abstract: A method of manufacturing an decoration film includes the steps of forming a semi-finished decoration film formed with a concave-convex pattern on a surface in a method of manufacturing a printing plate including exposure, cleaning, and drying from a photosensitive resin film; and irradiating laser on the concave-convex pattern of the semi-finished decoration film and removing an unnecessary portion to smooth concave-convex parts and/or provide difference in height of a convex part and depth of a concave part of the concave-convex pattern.

Abstract: A plastics shaping mold comprising a layer of hardened resin material fixedly superposed on a metal mold and defining an uneven shaping surface for forming an uneven surface pattern on plastic articles. The plastics shaping mold is prepared by a method comprising the steps of superposing a resin material in a fluid state on a master in sheet form defining an uneven surface inverse to the uneven shaping surface to be formed, allowing the resin material to harden and removing the master, thereby to form the layer of hardened resin material defining the uneven shaping surface.
