The present disclosure provides protective coverings formed by releasably attaching a mold to a metal structure over a connection, such as an exothermic or brazed connection, and injecting a hardening material into one or more fill ports in the mold. The hardening material hardens to form the protective covering encasing the connection.

A fixing device for securing a thin-walled component according to an embodiment includes: a support; a pressing portion provided on the support and including: a pressure generator located at a center of the support; and a plurality of pressure transmitters arranged around the pressure generator and extending in a radial direction of the thin-walled component; and a plurality of elastic members connected to the plurality of pressure transmitters, wherein the plurality of pressure transmitters are configured to move the plurality of elastic members in the radial direction.

The present system is configured to absorb, using a fluid medium in a reservoir, electromagnetic radiation to heat the fluid medium. The fluid medium may then conduct heat into a mold cavity formed by interior mold surfaces of at least two mold pieces. The fluid medium may heat up to, but not beyond, a phase transition temperature of the fluid medium, reducing instances of accidental damage to moldable material in a mold cavity during thermally-accelerated curing of the moldable material. In some instances a mold may be placed in liquid contained by the reservoir. In some instances, a mold may have integral reservoirs in individual mold pieces.

A decorative optical element that has an appearance of a glass optical element includes an optically transparent body having a faceted globular portion defined by a solid volume of polymeric material. A luminaire, such as for a street light, employs the decorative optical element and an LED circuit board mounted to the circuit board.

A method for producing an optical component, including a step of polymerizing a polymerizable composition including a polythiol component and a polyisocyanate component in a molding die, wherein the molding die includes a pair of molds and a tape for separating these molds apart and fixing the molds, the tape has a tape substrate and a tacky adhesive layer, and a percentage moisture content in the tacky adhesive layer is 950 ppm by mass or less, and also a molding die tape for a spectacle lens substrate, the molding die tape having a tape substrate and a tacky adhesive layer, wherein a percentage moisture content in the tacky adhesive layer is 950 ppm by mass or less.

The invention is directed to a process for producing a cured 3D product comprising the following steps: (a) providing a form negative mould of the 3D product comprising of one or two formed plastic sheets as obtained by thermoforming corresponding with the shape of the 3D product; (b) adding a liquid curable composition to the mould such that the inner surface of the mould is covered by the curable composition; and (c) solidifying the curable composition wherein a solidified layer or body is formed having the shape of the 3D product; wherein the cured 3D product is a radiation cured 3D product; and wherein the step (c) a radiation curable composition is solidified by radiation through the plastic sheet of the mould to form a solidified layer having the shape of the 3D product.

A molding system and method, allowing for the repeated use of the same molding insert for purposes of elaborate objects molding is described. The proposed method allows for multiple moldings of intricate shapes and curvatures improving the mass production of the jewelry moldings. During the process, the raw molding material is squeezed through the narrow opening inside the mold form under pressure. As the molding material enters the mold form, it is coated with a coating fluid. After the curing, the molding material could be easily removed through a narrow cavity opening, promptly reassembling back to the shape of the insert for continuous use in the next steps of the molding procedure.

According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

An apparatus for making a three-dimensionally curved object, said apparatus comprising a membrane having a moulding surface, which is configurable into a predetermined shape by individually adjusting an array of actuators acting on the surface opposite the moulding surface of said membrane, wherein the membrane is a ferromagnetic membrane and the actuators are provided with magnetic joints at the distal ends of said actuators.
