The manufacturing method of the invention is a method for manufacturing a fiber-reinforced resin substrate or resin molded body obtained by impregnating a reinforcing fiber material with a thermoplastic resin, including placing the reinforcing fiber material on a molten resin of the thermoplastic resin and pressurizing the same to impregnate the reinforcing fiber material with the molten thermoplastic resin, and subsequently, cooling and solidifying the reinforcing fiber material impregnated with the molten thermoplastic resin.
Application device, imprinting apparatus, and method for manufacturing object
Provided is an application device capable of extracting an imprinting material in which impurities are mixed from a container of the application device and supplying new imprinting material to the container of the application device. An application device according to the present disclosure is used to supply an imprinting material to a substrate in an imprinting apparatus that forms a pattern on the imprinting material on the substrate by using a mold. The application device includes a container unit that contains the imprinting material, and an ejecting unit that is provided on the container unit and that ejects the imprinting material contained in the container unit toward the substrate. The application device is detachably attachable to the imprinting apparatus.
Compression molding device
A compression molding device, which can obtain a high compression molding force without lowering the efficiency of article production, and whose molding means has a long service life, is provided. In the compression molding device, a one-side mold assembly moving means (58) includes a toggle link mechanism including two links (62) and (64), and a toggle link mechanism operating means (60), while an opposite-side mold assembly moving means (108) includes a hydraulic cylinder mechanism. When a one-side mold assembly (16) and an opposite-side mold assembly (18) are to be brought from an open state into a closed state, the one-side mold assembly (16) is first moved to a nearly closed state by the one-side mold assembly moving means (58), and then the opposite-side mold assembly (18) is moved from the nearly closed state to the closed state by the opposite-side mold assembly moving means (108).
METHOD AND DEVICE FOR MANUFACTURING ARTIFICIAL MARBLE HAVING STRIPE PATTERN
The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.
Method for manufacturing a sandwich panel
A sandwich panel includes a reinforcement member having a recess formed to extend in a longitudinal direction over a predetermined length and open laterally. The thermoplastic resin core material has a rectangular flat board-like shape, and includes a protrusion which is disposed on a peripheral side surface portion thereof and which is capable of being laterally press-fit with respect to the recess. The protrusion has opposing surfaces respectively opposing mutually opposed inner surfaces of the recess, the opposing surfaces being oriented so as to protrude from the peripheral side surface portion. At least one of the opposing surfaces is provided with a plurality of protuberances disposed at an interval in the longitudinal direction. Each of the protuberances has a predetermined height from the opposing surfaces enabling the protuberances to tightly contact the inner surfaces of the recess at the time of press-fitting.
Three dimensional netted structure
A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded. An apparatus and a method for manufacturing the three-dimensional netted structure.
THREE-DIMENSIONAL MOLDED ARTICLE
A decorative member that is a three-dimensional molding article includes a sheet, a lens portion, and an image-forming portion. The sheet has a light-transmitting property and has a first sheet surface that is curved. The lens portion is provided on the first sheet surface so as to curve along the curved surface. The lens portion has a plurality of protruding lenses disposed in parallel. A minimum value of widths of the lenses is in a range of 25.4 m or more and 508.0 m or less. The image-forming portion is provided on a second sheet surface, and an image is formed on the image-forming portion. The curved surface has a first region to a third region having different normal directions and has a shape in which one of the normal directions of the respective regions is inclined to a plane including the other two normal directions.
MODULAR MOLDING ASSEMBLY
A molding apparatus defining a processing direction includes multiple molding modules spaced apart in a lateral direction perpendicular to the processing direction and a common reaction surface. Each molding module includes a frame and a mold roll that defines molding cavities. Each mold roll defines a respective pressure zone in cooperation with the reaction surface and each mold roll is movable with respect to the reaction surface by controlled operation of the frame. Molten resin is introduced into the pressure zones and forced into the molding cavities to form arrays of fastener elements extending from base layers of resin formed on the surfaces of the mold rolls. The fastener elements are withdrawn from the cavities while stripping the base layers from the peripheral surfaces.
ROLL-MOLDING
Discrete male touch fastener elements are molded of thermoplastic resin extending from a common, flexible base sheet, by introducing molten resin to a molding nip between two counter-rotating rolls consisting of a mold roll and a pressure roll arranged such that their rotation axes are parallel and together define a common plane containing each of the rotation axes. Solidified resin is stripped from molding cavities of the mold roll after the cavities have passed a rotating reaction roll forming a pressure nip with the mold roll. The reaction roll is spaced from the pressure roll by a distance less than an outer diameter of the mold roll, and the mold roll is simultaneously held against both the pressure roll and the reaction roll in a non-planar roll stack.
Method for Molding Plastic Materials
A method for material handling and mold filling is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The method therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A method of using a multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.
