A mold assembly and method for fabricating an infiltrated drill bit may comprise a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, an infiltration chamber defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated drill bit, a displacement core arranged within the infiltration chamber and having one or more legs that extend therefrom, a metal blank arranged about the displacement core within the infiltration chamber, and one or more thermal elements. A method may comprise providing a mold assembly having component parts that include a mold that forms a bottom of the mold assembly and a funnel operatively coupled to the mold, imparting thermal energy to the infiltration chamber with one or more thermal element, and heating contents contained within the infiltration chamber.

Mold assemblies that actively heat infiltrated downhole tools

An example mold assembly for fabricating an infiltrated downhole tool includes a mold forming a bottom of the mold assembly, and a funnel operatively coupled to the mold. An infiltration chamber is defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool. One or more thermal elements are positioned within at least one of the mold and the funnel, and the one or more thermal elements are in thermal communication with the infiltration chamber.

An example insulation enclosure includes a support structure having a top end, a top wall provided at the top end, a bottom end, and an opening defined at the bottom end for receiving a mold within an interior of the support structure. Rigid insulation material may be supported by the support structure and extending between the top and bottom ends and across the top end. The rigid insulation material may extend between the top and bottom ends and consist of one or more sidewall insulation loops that extend along a circumference of the insulation enclosure.

A heat containment apparatus may include a housing having an access gap, the housing being formed of an insulating material. Alternatively, a heat containment apparatus includes a housing being an expandable structure having an access gap, the housing including an insulating material. Heat containment apparatuses may be used in conjunction with performing high temperature operations and/or low temperature operations to at least portions of substrates contained therein.

Heat containment apparatus

An example insulation enclosure includes a support structure having at least an inner frame and providing a top end, a bottom end, and an opening defined in the bottom end for receiving a mold within an interior of the support structure, and a radiant barrier positioned within the interior of the support structure, the radiant barrier including a front surface arranged to face the mold and a back surface facing the support structure, wherein the radiant barrier interposes the mold and the support structure to redirect thermal energy radiated from the mold back towards the mold.

Insulation enclosure with a radiant barrier

A blank may include a tang section, a base section, and an angled section with a recess. The tang section may have an outer surface with an outer diameter. The base section may have an outer surface with a diameter greater than the outer diameter of the tang section. The angled section may lie between the tang section and the base section and may have an outer surface that transitions in diameter from the outer diameter of the tang section to the outer diameter of the base section. The recess in the angled section may be shaped to engage a tip of a former.
