An apparatus and method for manufacturing a downhole tool that reduces failures occurring along a bondline between a cemented matrix coupled around a blank. The cemented matrix material is formed from a powder and a binder material. The blank includes an internal blank component and a coating coupled around at least a portion of the surface of the internal blank component. The internal blank component includes a top portion and a bottom portion. The internal blank component is substantially cylindrically shaped and defines a channel extending through the top portion and the bottom portion. The coating is a metal in some exemplary embodiments. The coating reduces the migration of the binder material into the blank thereby allowing the control of intermetallic compounds thickness within the bondline. | ||||||

An annular clean metal casting mold has a mold body which includes a cold bottom mold plate and a peripheral cold mold plate in connection with the cold bottom mold plate. An annular hot preservation layer is disposed inside the peripheral cold mold plate. A cyclic clean crystalline region is formed between the peripheral cold mold plate and the annular hot preservation layer. A sacrificial crystalline region is formed inside the cyclic hot preservation layer. As the outer race of the annular clean crystallization zone contacts large area of the peripheral low cold mold plate, releasing heat rapidly, while the inner race contacts the annular hot preservation layer 3, heat dissipation is extremely slow, naturally result in forming orientational crystallization. The vast majority of impurities and segregations in the liquid metal are gathered at the portion contacting with the annular hot preservation layer, and thus after the liquid metal is solidified, the gathered impurities and segregations can be removed easily, to obtain a clean casting ingot. |

186 | METAL MOLD FOR MANUFACTURING A STRAIGHT WAX BODY FOR A VALVE AND STRAIGHT METAL BODY FOR A VALVE THUS OBTAINED | EP10858199.2 | 2010-10-08 | EP2626155A1 | 2013-08-14 | Faraon Chaul Huerta, Adma Elena |
The present invention relates to a metal mold for manufacturing a straight wax body for a valve and to the straight metal body thus obtained, said metal mold succeeding in eliminating the traditional concave shape of the ball-type valve body, inside which, and during fluid flow distribution, the flow from the fluid inlet cavity to the fluid distribution cavity causes a flow loss in the direction of the fluid flow outlet via the fluid outlet cavity, thus creating a steep drop in pressure, meaning that by eliminating the concave part of the ball-type valve body and making the fluid inlet, distribution and outlet cavities straight and much wider, a straight valve body is obtained, thus preventing the steep drop in pressure and flow loss. The metal mold in the invention, which uses the lost-wax or ceramic casting process to manufacture the straight wax body for a valve of any design, is constituted starting with a rectangular or square housing that includes an orifice through which the graded wax is introduced at a certain temperature for forming the straight wax body for the valve inside the metal mold. |

New methods and systems for manufacturing a three-dimensional form, comprising steps of providing a plurality of particulates; contacting the particulates with an activation agent; contacting particulates having the activation agent with a binder material that is activatable by the activation agent; at least partially hardening the binder for forming a layer of the three-dimensional form; and repeating these steps to form the remainder of the three-dimensional form. Following sequential application of all required layers and binder material to make the form, the unbound particles are appropriately removed (and optionally re-used), to result in the desired three-dimensional form. The invention also contemplates a novel method for preparing a form, where unbound particulates free of binder material are re-claimed. | ||||||

The invention relates to a method for producing ingot molds (1) for pig casting installations used for producing pigs. According to the invention, mill bars (2) comprised of copper are used as starting material. Said mill bars are, in particular, comprised of a copper alloy which is suited for cold forming and which has a comparatively high degree of elongation. The mill bars are formed into the shape of ingot molds by means of a conversion process in which the mill bars are formed under tensile conditions or under a combination of tensile and compressive conditions. The invention also relates to an appropriate device for producing the ingot molds for pig casting installations. | ||||||

Komplizierte Formen, insbesondere solche die eine besonders ausgebildete Oberfläche aufweisen sollen, werden heutzutage üblicherweise durch spanabhebende Techniken hergestellt. Diese sind zeitaufwendig und lassen sich nur schwer automatisieren. Diese Nachteile sollen vermieden werden. Beim neuen Verfahren wird auf das Urmodell (2) eine Schicht (3) aus niedrigschmelzendem Material aufgebracht. n Auf die Schicht aus niedrigschmelzendem Material wird dann erst die die eigentliche Endform bildende Schicht (5) aus einem hochfesten und hochschmelzenden Werkstoff aufgebracht. Durch Aufschmelzen des niedrigschmelzenden Werkstoffs kann die Endform leicht abgetrennt werden. |
