A big proportion of working forces is employed in factories. The labor force operates machinery and equipment day in and day out manufacturing products that are used in many other industries. Most of these companies have inside fabricators that make spare parts for the factory. Most components of machineries are of metal and wears down because of constant use. An innovator can make good use of metal prototype fabrication.

Everyday a hairy creature gets up from its bed. It wonders around the surroundings bleary eyed. It takes stock situational stock and goes to the restroom to wash and clean up. Feeling hungry, it goes to the kitchen and ransacks the refrigerator for something to eat or cook. Once done, it bathes and clothes itself for another day of toil. This is the creature called man.

Great oceans surround the land area. Rivers and lakes catch rain water cascading from the mountain heights. Lush vegetation blankets large swaths of land where critters of all kinds scurry around. In forest canopies primates swing from branch to branch while serpents slither around tree trunks. Observing all this is the king of it all, this creature known as man.

The landmass is generally composed of solid ground called soil. But beneath it is a treasure trove of minerals and precious stones. Iron is the most common of all and it forms much of the inner and outer crust of the earth. It is abundant as a result of combination of dense particles that collided during the universe formation.

Ancient civilizations used metals in different alloys or mixtures. Bronze was the first to be fully exploited and an epoch is even named after it. This metal had low melting temperature and could be hammered into shape easily. This characteristic though is also its drawback. It tended to be soft and could easily be pierced.

Unprocessed rocks are withdrawn from the inner depths of the earth in many ways. Quarrying is one of these. Tools and machines are used to remove topsoil to uncover the source. In early days this meant the use of a large manpower base. But modern techniques have made withdrawals easy and frequently.

Another way of getting iron ore from the bowels from earth is through blasting. This was only made possible with the invention of nitroglycerin explosives during the early stage of industrial age. Identified earth veins have holes drilled into it and pieces are inserted. This was then ignited from a distance by means of wires and fuses.

Open pit mining is now the common practice of extracting ores from the planet. These are very large excavating operations that involve various types of heavy equipment. Gigantic earth movers carry topsoil to the sidelines while motorized excavators do the digging. Rock cutting machinery are also used as are individual power tools.

The use of steel in most heavy industries today knows no end. Giant shipyards use tons and tons of steel to build ships that can carry heavy tonnage. The care manufacturing industry mostly uses metal in production vehicles. Alternative materials are now being pushed to ease the use of steel and its derivatives.
