The present invention discloses an apparatus and a method for manufacturing molding inductor. The apparatus mainly comprises a mold and at least one magnetic force generating unit. Particularly, the mold is designed to have one or more accommodation spaces to correspondingly receive one or more coils. On the other hand, the magnetic force generating unit is configured to apply a magnetic force to the accommodation spaces after a molding material doped with magnetic ferrite powder is filled into the accommodation spaces receiving with the coil therein. Consequently, the molding material is forced by a molding stress provided by the applied magnetic force to move effectively downward in the accommodation space, such that a molded body is eventually formed in the accommodation space.

A process for the production of composite materials at low temperatures, as well as a composite material obtained by the process and articles of manufacture comprising the composite material are provided.

A device and a method for heating and curing artificial stone with microwave are provided. The device includes a microwave curing cavity, within which an incompletely cured artificial stone is placed, and microwave is used to heat the artificial stone to completely cure the artificial stone; wherein, a frequency of the microwave is in a range of 3001120 MHz. The present disclosure provides a separately designed microwave curing cavity, and utilizes 3001120 MHz microwave having a large penetrating depth, to realize a rapid curing of a large-sized artificial stone.

The present invention provides an apparatus for manufacturing artificial marble including a granite soil storage unit for supplying a granite soil; a granite soil heating unit for heating the soil; a resin storage unit for storing a thermoplastic polyurethane (TPU) resin; a mixing-transporting unit for accommodating the resin and the heated granite soil therein and melting and mixing them to produce and simultaneously transport an artificial marble slurry; a material guide unit for guiding the soil and the resin into the mixing-transporting unit; a discharge unit for discharging the slurry; a mold supply unit for continuously supplying a mold for accommodating and molding the slurry; a mold guide unit for guiding the mold to accommodate the slurry; a forming unit for forming an artificial marble by applying vibration and pressure to the slurry; an extraction unit for extracting the mold; and a lamination unit for laminating and storing the mold extracted.

A method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring the mixture into a mold (20) an upper face being exposed; engraving the exposed upper face with a predefined precise pattern of grooves (30) coinciding with a pattern of thin veins to be obtained; impregnating at least the inner faces (31) of the grooves (30) with a moldable hardenable fluid mixture of a second material (12), the color of both materials being different; causing the collapse and closure of the grooves, a visible pattern of thin veins of a second material with a natural look being left behind; curing the artificial stone slab by subjecting it to vibration, compression and vacuum until the fluid mixtures of the first material and of the second material are hardened.

Disclosed are processes for producing molded polyurethane elastomers and products, such as filter end caps, that include such elastomers. The elastomers are the reaction product of a non-foaming reaction mixture comprising an isocyanate-reactive composition and an organic polyisocyanate prepolymer with an internal mold release agent.

A method for preparation of a mold (10) intended to form a slab from a mixture of agglomerate comprising the steps of depositing over the mold surfaces a sheet (15) of PVA-based plastic material so as to form with it a surface for subsequent contact with the mixture introduced into the mold for forming the slab, whereby in at least some areas a layer (14) of a fluid agent containing PVA in a solution is interposed between the sheet (15) and the mold surfaces. A plant for carrying out the method and a method for production of a slab are also described.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

A hollowed body component made by additive manufacturing is disclosed. The hollow body has a longitudinal extent, an exterior surface and an interior surface, the interior surface having a first side and an opposing, second side. A first set of curved supports are curved along lengths thereof and extend between the first side and the opposing, second side to support the hollow body at least during the additive manufacturing thereof. Some embodiments include cooling passages open to the interior surface. Here, the curved supports extend between opposing pairs of passage-free spaces on the interior surface to support the hollow body at least during the additive manufacturing thereof. In one example, the component is an impingement insert for a hot gas path component.

A composite body includes a bound mixture, a resin and a coating. The bound mixture includes a binder and a plurality of particles. The resin fully infiltrates the bound mixture such that the resin fully infiltrates an entire thickness of the bound mixture. The composite body is formed by combining a plurality of particles with a binder to form a bound mixture and infiltrating the bound mixture with a resin to a depth such that substantially an entire thickness of the bound mixture contains the resin. The coating defines an outer layer of the composite body.
