2. Ingot - Wikipedia

   en.wikipedia.org/wiki/Ingot

   Aluminium ingot after ejection from mold Pouring molten gold into a mold at the La Luz Gold Mine in Siuna, Nicaragua, about 1959. An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. [1] In steelmaking, it is the first step among semi-finished casting products. Ingots usually ...

3. Semi-finished casting products - Wikipedia

   en.wikipedia.org/wiki/Semi-finished_casting_products

   In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2). [1]

4. Permanent mold casting - Wikipedia

   en.wikipedia.org/wiki/Permanent_mold_casting

   The mold life is dependent on four factors: the mold material, the pouring temperature, the mold temperature, and the mold configuration. Molds made from gray cast iron can be more economical to produce but have short mold lives. On the other hand, molds made from H13 tool steel may have a mold life several times greater.

5. Metal casting - Wikipedia

   en.wikipedia.org/wiki/Metal_casting

   Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting. Riser: An extra void in the mold that fills with molten material to compensate for shrinkage during solidification. Gating system: The network of connected channels that deliver the molten material to the mold cavities.

6. Continuous casting - Wikipedia

   en.wikipedia.org/wiki/Continuous_casting

   The depth of the mold can range from 0.5 to 2 metres (20 to 79 in), depending on the casting speed and section size. The mold is water-cooled to solidify the hot metal directly in contact with it; this is the primary cooling process. It also oscillates vertically (or in a near vertical curved path) to prevent the metal sticking to the mold walls.

7. Investment casting - Wikipedia

   en.wikipedia.org/wiki/Investment_casting

   Investment casting is used with almost any castable metal. However, aluminium alloys, copper alloys, and steel are the most common. In industrial use, the size limits are 3 g (0.1 oz) to several hundred kilograms. [23] The cross-sectional limits are 0.6 mm (0.024 in) to 75 mm (3.0 in).

8. Shell molding - Wikipedia

   en.wikipedia.org/wiki/Shell_molding

   Shell mold casting allows the use of both ferrous and non-ferrous metals, most commonly using cast iron, carbon steel, alloy steel, stainless steel, aluminium alloys, and copper alloys. Typical parts are small-to-medium in size and require high accuracy, such as gear housings, cylinder heads, connecting rods, and lever arms.

9. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   Typical moulds are constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. [17]: 176 The choice of material for the mold is not only based on cost considerations, but also has a lot to do with the product life cycle. In general, steel moulds cost more to construct, but their longer lifespan offsets the ...
