Non-expendable mold casting[ edit ] The permanent molding process Non-expendable mold casting differs from expendable processes in that the mold need not be reformed after each production cycle.
This technique includes at least four different methods: This form of casting also results in improved repeatability in methoding of steel casting produced methoding of steel casting delivers Near Net Shape results. Permanent mold casting[ edit ] Main articles: Permanent mold castinglow-pressure permanent mold castingand vacuum permanent mold casting Permanent mold casting is a metal casting process that employs reusable molds "permanent molds"usually made from metal.
The most common process uses gravity to fill the mold.
However, gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush castingproduces hollow castings.
Common casting metals are aluminummagnesiumand copper alloys. Other materials include tinzincand lead alloys and iron and steel are also cast in graphite molds.

Permanent molds, while lasting more than one casting still have a limited life before wearing out. Die casting The die casting process forces molten metal under high pressure into mold cavities which are machined into dies. Most die castings are made from nonferrous metalsspecifically zinccopper, and aluminium-based alloys, but ferrous metal die castings are possible.
The die casting method is especially suited for applications where many small to medium-sized parts are needed with good detail, a fine surface quality and dimensional consistency.
Semi-solid metal casting[ methoding of steel casting ] Methoding of steel casting article: Semi-solid metal casting Semi-solid metal SSM casting is a modified die casting process that reduces or eliminates the methoding of steel casting porosity present in most die castings.
Rather than using liquid metal as the feed material, SSM casting uses a higher viscosity feed material that is partially solid and partially liquid.
A modified die casting machine is used to inject the semi-solid slurry into re-usable hardened steel dies.
The high viscosity of the semi-solid metal, along with the use of controlled die filling conditions, ensures that the semi-solid metal fills the die in a non-turbulent manner so that harmful porosity can be essentially eliminated.
Used commercially mainly for aluminium and magnesium alloys, SSM castings can be heat treated to the T4, T5 or T6 tempers.
The combination of heat treatment, fast cooling methoding of steel casting from using un-coated steel dies and minimal porosity provides excellent combinations of strength and ductility.

Other advantages of SSM casting include the ability to produce complex shaped parts net shape, pressure tightness, tight dimensional tolerances and the ability to cast thin walls.
Centrifugal casting silversmithing Methoding of steel casting this process molten metal is methoding of steel casting in the mold and allowed to solidify while the mold is rotating.
Metal is poured into the center of the mold at its axis of rotation. Due to centrifugal force the liquid metal is thrown out towards the periphery. Lead time varies with the application.

Industrially, the centrifugal casting of railway wheels was an early application of the method developed by the German industrial company Krupp and this capability enabled the rapid growth of the enterprise.
Small art pieces such as jewelry are often cast by this method using the lost wax process, as the forces enable the rather viscous liquid metals to flow through very small passages and into fine details such as leaves and petals.
This effect methoding of steel casting similar methoding of steel casting the benefits from vacuum casting, also applied to jewelry casting.
