A system for producing at least one three-dimensional element on a visible face of an external part element of a timepiece implementing this process, the system including a mould formed by the reversible assembly of a first part and a second part configured to receive a support plate of the external part element, the mould including at least one cavity formed by associating the first part including at least one impression with the visible face of the external part element, each cavity helping produce a blank of the three-dimensional element from an over-moulding by injecting injectable material onto the visible face, and a device for applying a coating onto the blank over-moulded on the visible face of the external part element helping finalise this blank of the three-dimensional element.

A method of providing a tool with a conformal cooling passage includes rough machining a cavity generally corresponding to a manufactured part shape using CAD data. Conformal cooling slots are cut in the cavity using the CAD data. The conformal cooling slots are welded shut using the CAD data to provide conformal cooling passages. A class A surface is machined over the conformal cooling passage and corresponds to a finished manufactured part shape using the CAD data.

A mold for resin injection molding 1 having a shaping region formed by a low-density shaped portion 22 and a high-density shaped portion 21 in which each ventilation channel 32 for gas existing between an external region and a molding portion region forms a hollow state surrounded by a peripheral wall having any one or both of the high-density shaped portion 21 and the low-density shaped portion 22, and the secondary vent 33 connecting communicatively with a region molding portion is formed only by a low-density shaped portion 22 with thickness thinner than that of the shaping region.

A tool assembly and a method for manufacturing and sealing a tool assembly for manufacturing an article includes building a tool assembly using additive manufacturing or 3D printing processes.

An injection mold component for molding the outer surface of a preform neck, which allows improved cooling of the preform neck inside the mold, while at the same time reducing the mold cycle time. A related production process of said injection mold component, which allows the section of the cooling channels to be optimized, determining a more effective cooling, is also described.

A method of making a forming wheel includes mixing and melting an electrically conductive material, a latex rubber material, and a polycarbonate material to produce a weatherproof material mixture, blending carbon black with polyethylene to produce an electrically conductive additive, positioning an injection mold of the forming wheel in fluid communication with an exit end of a heating barrel, injecting the weatherproof material mixture into an entry end of the heating barrel, introducing the electrically conductive additive through a lateral port of the heating barrel proximate to the exit end to partially mix with the weatherproof material mixture to produce an injection mixture, and injecting the injection mixture into the injection mold to produce the forming wheel.

A forming tool with forced thermal fluid-based spatio-temporal temperature control of a surface of the tool has a subsurface manifold underlying at least a part of a forming surface of the tool and a number P of at least 6 ports, each port fluid coupled respectively to the manifold via respective channels, where the ports exit the tool at disparate points, with each pair of ports in fluid communication via the manifold. This structure allows manifold path diversity for varying thermal fluid supply and drainage. The manifold may be reinforced.
