| 20130081776 | Methods For Forming Molded Components Having A Visible Designer Feature and/or Improved Operational Properties Via A Porous Preform - A method for forming a casted component using a porous structure. The casted component may include a visible design feature formed in part by the casted component and in part by a body material also forming other parts of the component. The casted component may be a brake rotor having a mixed-material composite formed in part by the casted component and in part by a body material also forming other parts of the rotor. The porous structure can include a ceramic foam or a metal mesh. | 04-04-2013 |
| 20140090795 | LED HEAT SINK AND MANUFACTURING METHOD THEREOF - An LED heat sink and a manufacturing method thereof are disclosed. The LED heat sink includes a main body having a heat receiving section and an extended heat transfer section. The heat transfer section is externally provided with a plurality of receiving grooves for correspondingly connecting with a plurality of radiating fins. The LED heat sink manufacturing method includes the steps of molding a main body using a half-molten metal material and cooling the main body, so that the cooled main body is connected with a plurality of radiating fins to form an integral unit. With the LED heat sink manufacturing method, it is able to manufacture an LED heat sink having a relatively complicated radiating fin structure or being formed of two or more types of materials, and to largely reduce the time, labor and material costs of the LED heat sink. | 04-03-2014 |
| 20140190651 | Apparatus and Method for Embedding an Element - Embodiments of the present invention provide apparatus for forming a component from a solidified fluid medium. The apparatus comprises a body defining a cavity into which the fluid medium may be introduced, the cavity optionally being shaped to define a shape of the component, and a carrier for supporting one or more elements to be embedded in the component. The carrier is arranged to be introduced into the cavity to support the one or more elements within the cavity whilst the fluid medium is introduced into the cavity. Embodiments of the invention are useful in a range of fabrication technologies including casting of metals and injection moulding operations. | 07-10-2014 |
| 20150027654 | MOLD APPARATUS FOR CASTING CYLINDER BLOCK - A mold apparatus for casting a cylinder block having a cast-in cylinder liner by installing the cylinder liner inside a cavity and pouring a melt into the cavity, the mold apparatus includes a first mold and a bore pin. The first mold defines a deck surface of the cylinder block. The bore pin is in the first mold so as to hold the cylinder liner inside the cavity when the mold is closed. The bore pin is configured to hold the cylinder liner interposed by a gap, and the gap is arranged so as to enable gas produced during the cast-molding to be discharged therethrough. | 01-29-2015 |
