The disclosure relates to a dipping former, to a process for producing the dipping former and to the use of the dipping former in a latex dipping process. The dipping comprises (i) a molded core part, and (ii) a dipping former shell having a surface in one piece. The dipping former is obtainable by a molding process comprising the following steps: —providing a first cavity and a second cavity; —injection molding or blow molding a first material into the first cavity thereby forming a molded core; —transferring the molded core form the first cavity into the second cavity; and —injection molding of a second material into the second cavity thereby overmolding the molded core, or at least a part thereof, with the second material.

Disclosed are a polyurethane condom (100) with an adhesive layer (20) and a preparation method therefor. The polyurethane condom (100) with the adhesive layer (20) comprises a first polyurethane film layer (10), the adhesive layer (20) on the first polyurethane film layer (10), and a second film layer (30) on the adhesive layer (20), wherein the adhesive layer (20) includes 0 to 100% by weight of a polar component, 0 to 100% by weight of a non-polar component, and 0 to 100% by weight of a material composed of a polar and non-polar hybrid component, and has a thickness of 0.1 to 30 μm.

An orthopedic precast comprises a knitted shell portion and a knitted flexible portion. The precast is positioned about a limb or other mold, and heat or other hardening agent is used to harden the shell portion, while retaining flexibility in the flexible portion. Contemplated hardening agents include light, heat, and chemical polymerizing agents. In some embodiments the shell portion includes threads or yarns comprising a thermoplastic, which is then hardened by heating the thermoplastic sufficiently to at least partially melt, and thereby fuse together some of the threads or yarns, and then cooling to ambient temperature. In other embodiments, the precast is contained in a bag or other airtight container, along with a self-heating composition that is triggered to release heat upon contact with oxygen. In still other embodiments, the precast includes a prepolymer of other polymerizable composition, which is polymerized by effective application of light, heat, and/or chemical agent(s).

Various embodiments of molds and methods are disclosed herein for fabricating a radio frequency (RF) coil. The disclosed mold includes a cylindrical inner core having a first helically shaped groove formed within an outer surface of the cylindrical inner core, and a two-piece compression sleeve having a second helically shaped groove formed within an inner surface of the two-piece compression sleeve. When portions of the two-piece compression sleeve are attached together, the two-piece compression sleeve surrounds the cylindrical inner core and provide a compressive force to a conductor arranged within the first and second helically shaped grooves to fabricate the RF coil. In some embodiments, a three-dimensional (3D) printing process may be used to fabricate each piece of the mold separately.
