Since the dawn of time, mankind has been shaping things from metal. Earliest records speak of “stones from heaven”, referring to meteorites falling from the sky containing iron, the core ingredient of metal and metalworking.
Meteor falling from the sky
Around 9,000 BC, records acknowledge one of man’s first metal accomplishments, a bull-shaped gold ornament made from metalworking. From the Copper age, to the Bronze Age, and on into the Iron Age, man has been perfecting the craft of metalworking and metal casting. Over that time span, metal has been used to shape bowls, manhole covers, pipes, skillets, tools, and weapons.
During the Industrial Age, essentially 18th Century and onwards, demand for machined components and complex machine parts caused metal casting to reach all new heights. Parts could no longer just be metal stamped or machined:
Metal casting was required!
Foundries are the very establishments that transform metal into metals castings. They engage in the pouring of metal into molds or dies, to form castings. Essentially, any hard metal that can be melted, can be cast.
There are various types of foundries involved in metal casting:
The core distinction between these foundries is whether ferrous metal or nonferrous metals are used. Ferrous metals are those containing iron and non-ferrous metals do not contain iron. This is an important distinction, because the nature of hazards and injuries may differ.
Iron, Grey Iron, and Steel. Ferrous Foundries are the most common casting foundry. Here are some products made from these metals:
Yep, a common engine block
10 points for whomever can identify the make
Engine blocks, machine tool frames, pipe-fittings, pumps, and valves
Guns, rifles, Aerospace, medical equipment, and high impact wear products.
Ferrous Foundries have a high number of recordable injury cases, with 6.1 for every 100 employees. Steel Foundries have the highest, with around 6.9 for every 100 employees.
A penny is made mostly of zinc
Silver, Platinum, Gold, Copper, Nickle Titanium, Aluminum, Tin, and Zinc
Nonferrous foundries have around 6.3 recordable cases for every 100 employees, with aluminum foundries coming in around 7.8 recordable cases.
Depending on the complexity of the casting performed, foundries will follow a similar casting process.
Here is a look at the Casting Process:
The pattern provides a precise replica of the desired part or end product to be made.
Example of a Gearbox pattern
Preparation of the mold, the rigid frame into which liquid metal is poured, forming a casting. The core making function involves cores being inserted into a mold, shaping the inside of a casting. Behind metalworking, this part of a foundry employs the most workers.
Molten metal is poured into the mold.
Molten Metal being poured
Once the molten liquid has been poured, the mold cools rapidly.
During shakeout, the metal is removed from its mold. During Cleaning and Shot Blasting, focus is placed on the removal of sand.
Castings are heat treated, excess metal is trimmed and removed, castings are polished and the finished part is inspected.
