COPPER AGE

Copperage datesbackto 4500 B.C.

Casting originated in 3200 B.C.inmiddle east

precisely in Indiaand China Both expendable and permanentmoulds were

used

Loamand Clay used for expendable moulds

Stones were used for permanentmoulds

Core was used formaking hollow parts

The mainmetal used forcasting was Copper

THE BRONZE AGE

Bronze age dates back to about 2000 B.C. Tin was mixed with Copper to get better

hardness and strength.

The Chinese Piece Mold Technique

1) Model made

2) Mould made of soft clay

3) Mould removed by sectioning

4) Model shaved down to serve as

core

5) Assemble together

6) Pour metal

Ancient Egyptian Bronze Casting

Lost wax casting was vastly used to make statues, swords, daggers, coins and

jewelry

Painting found from 1430

BC showing different

Casting methodologies

THE IRON AGE

1200 B.C.

Iron was discovered and introduced in the industry by smelting the iron ores

Earlier Iron had less strength and was blunted easily thats why a lot of attention was not paidtowards Iron

Later it was found that Iron could become stronger than Copper and Bronze by cold working andquenching.

The process of purifying iron ores was widely spread and iron took over the industry

800-700 B.C.

Chinese started to produce cast iron

645 B.C.

Chinese are found to use sand moulds for casting of iron.

500 A.D.Steel was used for the first time to make Crucibles in India. But this process got lost again

MIDDLE AGES TO 1800 1455

In Dellinburg Castle in Germany cast iron pipes were used for the first time totransport water.

1480

Vannoccio Biringuccio was born. Known as The father of Foundry industry

1642

Americas first foundry Saugus Industries was established near Lynn,Massachusetts

1730

Abraham Darby was the first to use coke as fuel in his melting furnace in England.

1750

Benjamin Huntsman reinvents the process of casting steel in England. Hecompletely melted iron to get uniform composition

19TH CENTURY

1809Centrifugal casting was developed by A. G. Eckhardt in England

1818

First cast steel was produced in the U.S. at the Valley Forge Foundry

1825

Aluminum was isolated from its ores which is the most common metal in theearth's crust,

1837

First dependable molding machine was marketed and used by the S. Jarvis Adams

Company in Pittsburg

1845

The open hearth furnace was developed

1863

Metallography, etching, polishing, and microscopic evaluation of metal surfaces, is

developed by Henry C. Sarby in England. It is the first process to physically examine

the surface of castings for quality analysis.

change

1896

American Foundrymen's Association is formed.

1897

Investment casting (lost wax casting) is rediscovered by B.F. Philbrook. He used it

to cast dental inlays.

EARLY 20TH CENTURY 1906

First electric arc furnace is used in the U.S. at Holcomb Steel Co. in Syracuse, NY

1923

International Committee of Foundry Technical Associations established in ZurichSwitzerland

1924

Dr. W.H. Hatfield invents 18/8 stainless steel (18% chromium, 8% nickel)

1930

Professors from University of Michigan introduced Spectrography for metal analysis.

1930

First high-frequency coreless electric induction furnace was introduced in the U.S.Installed in the Lebanon Steel Foundry

1965

The Scanning Electron Microscope is invented by the Cambridge University EngineeringDepartment in England

1968

The Coldbox process is introduced by L. Toriello and J. Robins for core making aiming atmass production


16/17

LATE 20TH CENTURY

Early 1970s

The Semi-Solid Metalworking (SSM) process is conceived of at MassachusettsInstitute of Technology. It combines aspects of casting with aspects of forging

1971

The Japanese develop V-Process molding. This method uses unbonded sand and a

vacuum 1971

Rheocasting (hot forging) is developed at Massachusetts Institute of Technology.

1996

Cast metal matrix composites are first used in a production model automobile inthe brake rotors

1997

Electromagnetic casting processes developed by Argonne and Inland SteelCorporation. Electromagnetic edge containment greatly reduces cost and energyexpenditures in steel production.
