A method and apparatus for forming a core for a dual core golf ball is disclosed herein. A headblock is pressed against a mold tool wherein a hemispherical protrusion of the headblock compresses a slug within a first hemispherical cavity to form a first half shell outer core component. An inner core sphere is placed within the first half shell outer core component. An upper section of the mold tool is assembled onto a lower section of the mold tool to place a second half shell outer core component within an upper hemispherical cavity over the inner core sphere within the first hemispherical cavity to form a dual core component for a golf ball.

Disclosed are a gradient resin, a preparation method therefor and the use thereof. The gradient resin of the present application is formed by fusing different layers with color transition changes, wherein the color transition change between the two adjacent layers is in the range of 0.1% to 5 20%. The gradient resin is composed of, by mass percentage, 98%-99.99% of a resin powder and 0.01%-2% of a pigment.

A multilayer core molding method includes: an upstream process of obtaining an intermediate molded body 33; and a downstream process of performing molding using a downstream process molding apparatus 2, and wherein the downstream process includes: an intermediate molded body arrangement step of arranging the intermediate molded body on the intermediate plate cavity surface or the first downstream process mold cavity surface; and a first vulcanization step, performed after the intermediate molded body arrangement step, of vulcanization-molding the intermediate molded body until it is substantially or completely vulcanized, in a state in which at least the first downstream process mold and the intermediate plate are closed against each other.

An apparatus for forming a window of a display panel includes a mold configured to hold a plate in a concave portion, wherein the concave portion has a predetermined shape, and a transfer part configured to sequentially transfer the mold to a heating part, a forming part, and a cooling part. The heating part includes first and second heating modules respectively positioned on top and bottom portions of the mold and configured to apply heat to the top and bottom portions of the mold. The forming part is positioned above the mold and configured to jet a high-temperature gas onto the heated plate. The cooling part includes first and second cooling modules respectively positioned on the top and bottom portions of the mold and configured to cool the top and bottom portions of the heated plate. The mold is tilted at a predetermined angle relative to a horizontal plane.

A method for manufacturing a molded product with fine structure includes steps of, in a temperature-controlled stamper mold provided with a fine structure including a concavo-convex pattern having a width of 10 nm to 1 μm, forming a thermoplastic molten polymer layer to be in contact with the fine structure 20 of the stamper mold having been kept at a predetermined temperature and holding the thermoplastic molten polymer layer for a predetermined time so as to transfer the fine structure of the stamper mold to the thermoplastic molten polymer layer under gravity.

In the manufacture of double-walled corrugated extruded pipe it is desirable to form an integral connecting cuff that is of a single wall thickness and typically of a large diameter. The mold blocks and process parameters for forming of the cuff as part of an otherwise double-walled pipe requires a transition as the cuff moves past the die outlets. The present invention allows for accurate sensing and control of air pressure and temperature as the cuff moves past the die outlets. Improvements in both the die tooling and the method of manufacture are disclosed.

Provided is a composite material molding apparatus that can evenly heat a molding surface of a metal mold and shorten the cycle time. The composite material molding apparatus includes an upper die and a lower die having molding surfaces that accommodate a composite material member and shape the composite material member. The upper die and the lower die each have a planar graphite heater provided along installation positions so as to have a constant distance from the molding surface in a manner corresponding to the shape of the molding surface.

A process for manufacturing an article made of recovered rubber crumb is provided. According to the process:

a) crumb particles are mixed with particles of a solute;

b) a molded article is produced by molding the mixture from step a) in a closed mold under predetermined temperature and pressure conditions; and

c) the molded article is brought into contact with a solvent so as to dissolve at least one portion of the particles of said solute.

A main object of the present invention is to provide beneficial improvements relating to a method for producing a fiber reinforced plastic product, the method including curing while pressurizing a prepreg preform by using a core having a fusible part as means for pressurizing. A method for producing a fiber reinforced plastic product, the method including: a core preparation step of preparing a core comprising a fusible part and an outer skin covering the fusible part; a molding step of disposing a prepreg preform inside a mold together with the core, and heating and pressurizing the prepreg preform in the mold to obtain a cured product; and a core removal step of removing materials of the fusible part from the cured product, in the molding step, at least a portion of the prepreg preform being pressurized by expansion of the core, in which the fusible part comprises a first fusible part and a second fusible part having a fusion temperature higher than that of the first fusible part, a material of the first fusible part and a material of the second fusible part are incompatible with each other, and in the molding step, the first fusible part fuses partially or entirely, while the second fusible part does not fuse partially or entirely.
