A molding mold includes a shell mold provided with a plurality of vacuum suction holes and a backup mold for backing up the shell mold, a back surface of the shell mold and a front surface of the backup mold having the same shape and being fitted to each other. A ventilation groove is formed on the front surface of the backup mold or the back surface of the shell mold, leaving a receiving surface for receiving a mating surface, a plurality of striped grooves and ridges between the striped grooves are formed on the back surface of the shell mold or the front surface of the backup mold, the striped grooves having a feed pitch of 0.5 mm to 5.0 mm and a processing depth of 0.01 mm to 0.4 mm, and the vacuum suction holes and the ventilation groove communicate with each other through the striped grooves.

Described is a kit for moulding containers made of polymeric material, including a fixing base, having a plate-like shape, and a plurality of modules, which can be fixed to the fixing base and configured for defining, together with each other, a mould of a container to be moulded, where the mould has a containment space. The fixing base and the plurality of modules have reciprocal fixing elements for determining a stable and reversible coupling between the fixing base and the plurality of modules. Moreover, the base and/or the modules are designed to be connected to each other according to a plurality of different configurations and combinations in such a way that the mould can adopt a plurality of different shapes and dimensions.

A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.

A frame for a lightweight costume with air permeability, the costume, and a method for manufacturing them. The frame body for the costume includes a main body made of synthetic resin and a plurality of through holes penetrating the main body. The method includes a mold installation step of installing a mold in a predetermined three-dimensional shape on an elevating table, a resin member mounting step of mounting a resin member on a pedestal, a cover mounting step of mounting a cover covering the surface of the resin member on the pedestal, a heating step of heating the resin member and the cover, a vacuum molding step of bringing the mold into contact with the back surface of the resin member and then depressurizing the inside of the chamber, and a mold release step of releasing the frame body and the cover from the mold.

The invention regards a process for manufacturing a bicycle saddle, which provides a central through channel as well as a hull with a through hole (4′); a polyurethane layer and a liner.

By means of this process it is possible to make sure that, unlike the saddles of the state of the art, said central through channel is completely devoid of the edge present around the aforementioned, with significant advantages from both an aesthetic and functional point of view for the user.

A method and apparatus is presented. A portion is cut from a thermoplastic sheet of a first thermoplastic material based on a three dimensional model. The portion is secured to a mold. The portion and the mold are heated under vacuum to form a structure. The structure may take the form of a protective covering. In some illustrative examples, the mold may be formed of a second thermoplastic material based on the three dimensional model using additive manufacturing.

A component with a customized exterior surface and a method and tool for manufacturing the same are provided. The component may be formed via a plastic forming process with a forming tool, such that it has a surface texture formed on its exterior surface. The forming tool has at least one tool surface, which defines a mold cavity. The tool surface has a textured layer coupled thereto, such that the textured layer directly contacts a moldable material supplied to the mold cavity. The textured layer has a surface texture formed thereon resulting in the surface texture present on the textured layer being transferred to and formed on the exterior surface of the component during forming. The textured layer may be changeable or replaceable with respect to the at least one tool surface, such that a single tool may form components with different surface textures formed on the exterior surface thereof.
