Atomizer cores, atomizer core substrates and methods of manufacturing atomizer core substrates are provided as well as aerosol generating devices incorporating same. In one example, the atomizer core comprises a core body having a first surface and a second surface. The core body includes a substrate and a heater with a plurality of channels extending between the first surface and the second surface for transferring an aerosol precursor from the first surface through the substrate and the heater to the second surface, the heater being adapted to heat the aerosol precursor to form an aerosol at the second surface. In other embodiments an insulator is disposed between the substrate and heater and adapted to insulate the substrate at least partially from heat generated by the heater.

An induction furnace comprising a upper furnace vessel; an induction coil positioned below the upper furnace vessel; and a melt-containing vessel positioned inside the induction coil and communicably connected to the upper furnace vessel, wherein the positioning of the melt-containing vessel inside the induction coil defines a gap between an outside surface of the melt-containing vessel and an inside surface of the induction coil. A system for direct-chill casting comprising at least one an induction furnace; at least one in-line filter operable to remove impurities in molten metal; at least one gas source coupled to a feed port associated with the gas; and at least one device for solidifying metal by casting. A method of cooling an induction furnace comprising introducing a gas into a gap between an induction coil and a melt-containing vessel positioned inside the induction coil; and circulating the gas through the gap.

Provided is a high-pressure casting method and a high-pressure casting device which are capable of safe and high-quality casting of a high-fusion-point metal having a fusion point exceeding 1000 K. After melting a casting material (1) inside a melting container (2) of cartridge type, the melting container (2) is linearly moved to pass through a guide (14) attached to a casting port bush (13) to thereby be communicated with the casting port bush (13). The melting container (2) is brought into close contact with the guide (14) and is setting to a cooling state. After the elapse of prescribed time, a plunger (50) is brought into contact with a plunger tip (4), and is immediately transferred together with a molten metal to the casting port bush (13). The molten metal is pressurized inside the casting port bush (13), and is injection-filled into a cavity (10).

A combustion tube mounting system releasably mounts a combustion tube to an aperture in the floor of a furnace housing. The combustion tube has a base assembly with a cam and can be manually or automatically unlocked by cam pins in the floor for selectively engaging the cam for lowering the combustion tube from the floor of the furnace. When a new combustion tube is placed on the lower seal assembly and raised, it automatically aligns and engages the upper furnace seal and engages cams on the floor of the furnace housing which lock the combustion tube in place as it is introduced into the furnace.
