A method for the manufacture of a fiber-composite article for a bicycle frame or other bicycle component uses an outer mold configured to define an outer surface of the fiber-composite article and an inner mold configured to define an inner surface of the fiber-composite article. The method comprises: securing in the inner mold a supportive armature for a space-filling mandrel, the mandrel being configured to occupy a space within the inner surface of the fiber-composite article during lay up and curing of the fiber-composite article; forming the mandrel by injection molding a solidifiable fluid into the inner mold, around the armature, the solidifiable fluid being configured to form a solidified, molded material; applying a fiber composition to the mandrel; securing the mandrel with the fiber composition in the outer mold; heating the fiber composition in the outer mold to form the fiber-composite article and concurrently heating the solidified, molded material. In this manner, the fiber composition is compressed into the outer mold due to expansion of the solidified, molded material.

The object of the invention can be a method of manufacturing a product in the form of a sandwich comprising a core and outer layers. The outer layers may be composed of composite material comprising a fiber-reinforced polymeric matrix. The method uses an insert of heat-resistant material, for example silicone. The object of this invention can be to provide a method of manufacturing a sandwich that dissociates the choice of material of the core of the sandwich from the choice of the material of the outer layers.

A molded article comprising a container top is disclosed. The molded article includes a threadless frame defining an opening, a flip cap located substantially coplanar with, and integrally formed with, the frame, a compound hinge between the frame and the flip cap, the hinge allowing the flip cap to rotate about the hinge to rest on top of the frame, an in-mold lidding film having a perimeter molded to the frame such that the in-mold lidding film covers the opening defined by the frame, wherein the in-mold lidding film is removable from the frame, and a pull tab, formed from the in-mold lidding film, that extends past the opening defined by the frame.

The linear orientation of the user combined with a straight forward sliding stroke motion of present invention presents a novel new way to strike a golf ball toward the hole/target. By utilizing a linear line of site between the user's eyes, present invention, golf ball and the cup, this modern orientation of the golfer is similar to a marksman, the rifle, aiming site/scope and the bull's-eye of his target. While transversely rotating the body 90 degrees left or right (depending on handedness) compared to what has come before and incorporating the invention presented here, a new dimension in putting is opened, more accurately matching ones natural connection between their stance and aim. In nearly every other sport, this similar stance stoke/throw/shot is linear and constant due to its recognized effectiveness.

This method for manufacturing a resin structure (1) is provided with: a step for arranging a sheet (30) having a smooth surface (31) having a maximum height roughness of 3 μm or less, inside a forming mold (40) such that the smooth surface (31) faces an internal space (44) of the forming mold (40); a step for molding a resin molded body (10) to which the sheet (30) is adhered, by filling the internal space (44) with a resin; a step for separating the resin molded body (10) from the sheet (30), thereby forming a first region (11) having a maximum height roughness of 3 μm or less on at least a portion of the surface of the resin molded body (10); and a step for using a fluid conductive ink to form a wiring (20) on the first region (11).

The present disclosure includes systems, devices, and methods for preventing contamination during formation of an optical article. In some implementations, a device for preventing contamination of a mold cavity during injection molding of a function wafer includes a containment band having an annular base that defines a first opening configured to receive a functional wafer. The device also includes one or more sidewalls that project a first direction from and surround at least a portion of the first opening. The one or more sidewalls may be configured such that, during formation of an optical article, a first portion of the functional wafer is in contact with the one or more sidewalls.

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.
