A solid solution consisting of two or more chemical elements, one of which is a metal.
Argon Oxygen Decarburization, a three-step refining method (decarburization, reduction, and desulphurization) that removes carbon from high grade alloys. AOD is primarily used on stainless steel.
A cast devoid of secondary machining such as heat treatment.
Computer Aided Design. CAD is used for created computer-designed geometric models.
Computer Aided Manufacturing. CAM is often used to optimize production processes and improve the precision of dimensional tolerances.
A 6000 year old process of pouring molten metal into a mold to form solid metal shapes.
A metal's weight and composition before being subjected to heating.
A section of mold used for forming internal shapes in a casting.
An assembly consisting of one or more cores.
The opening in the mold where molten metal is poured.
Amount of tapering on molded or cast parts. Investment casting allows for eliminated or variable draft angles.
An alloy that is predominantly made up of iron.
Mold gasses trapped in molten metal during pouring.
Channels in the runner system that provide access for the molten metal to enter the mold cavity.
Hot Isostatic Pressing (HIP)
A process that applies simultaneous high temperature and high inert gas pressure, resulting in increased machinability and density.
Nonmetallic materials trapped in the casting, usually as a result of reoxidation, refractories, slag, and deoxidization.
Wax or thermoplastic pattern is surrounded in refractory slurry to form a mold. Once the refractory slurry dries, the wax or plastic is melted out. Molten metal is then poured into the mold in to fill the areas that were previously filled with wax.
The difference between a finished casting's weight and the total weight of the metal poured.
The cavity where the molten metal is poured to form the final solidified shape.
An alloy that is not predominantly made up of iron.
A wax or thermoplastic plastic replica of the final product to be made.
The use of computerized models, in conjunction with Thermojet printers, to produce function prototypes that help identify opportunities for design optimization before the manufacturing process begins.
Waste produced during the casting process.
The reduction in the molten metal volume that occurs during cooling.
An undesirable, non-metal film that forms on top of molten metal.
A watery mixture used to cover the wax pattern to form a mold.
The complete runner assembly system. Also known as the tree.
