At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The mold thickness adjustment mechanism includes a rod-shaped rotation member, a power source configured to rotate the rotation member around a rotation axis of the rotation member, the rotation axis being parallel to a longitudinal direction of the rotation member, and a pair of converters configured to convert rotation direction of the rotation member into a movement direction of the second platen. A mold clamping device for split molds includes polygonal first and second platens, a pressure receiving platen, and a toggle mechanism. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The toggle mechanism is disposed between the second platen and the pressure receiving platen and on a diagonal line of the second platen and configured to cause the first and second platens to approach or depart from each other.

A mold, a molding apparatus, and a method for manufacturing articles or components is used to manufacture an article or component of the article that at least partially comprises an ultraviolet (UV) curable material. The mold and apparatus comprise at least one mold wall formed of a cyclic olefin copolymer, which is in contact with UV radiation curable material and allows the article or component of the article to be exposed to UV radiation for a period of time in order to provide for at least partial cure thereof.

A mold clamping device includes: a fixed platen; a movable platen; a rotary platen provided on one platen of the fixed platen and the movable platen, to which a mold is attachable; and an extrusion device provided on the one platen and configured to extrude a molded article from the mold. The rotary platen is disposed at a side of a surface of the one platen facing the other platen to face the one platen and is rotatable via a bearing structure. The extrusion device is disposed on a surface of the one platen opposite to the surface facing the other platen. The bearing structure is configured to bear the rotary platen at a position away from a rotation center in a radial direction. The extrusion device has an ejector rod that protrudes radially inward than the bearing structure.

A method of forming a corrugated thermoplastic matrix composite sheet includes preheating a thermoplastic matrix composite sheet including a thermoplastic matrix and a reinforcement material to at least about a melting temperature of the thermoplastic matrix; preheating at least one of a pair of complementary corrugating tools to at least about a glass transition temperature of the thermoplastic matrix; compressing the preheated thermoplastic matrix composite sheet between the pair of complementary corrugating tools to form a corrugation in the thermoplastic matrix composite sheet; and holding the corrugation between the pair of complementary corrugating tools until a portion of the thermoplastic matrix composite sheet having the corrugation is below the melting temperature of the thermoplastic matrix to form the corrugated thermoplastic matrix composite sheet.
