Manufacturing
Human ancestors struck hard stone cores with hammerstones to create sharp edges. This process began at least 2.3 million years ago in Ethiopia's Great Rift Valley. The earliest direct evidence of tool usage dates back 2.5 million years. These early tools included choppers and scrapers used by hunter-gatherer communities. They helped form other tools from softer materials like bone and wood. A prepared-core technique emerged around 300,000 years ago during the Middle Paleolithic. Multiple blades could be rapidly formed from a single core stone. Pressure flaking developed approximately 40,000 years ago in the Upper Paleolithic. Wood, bone, or antler punches shaped stones very finely. Polished stone axes appeared during the Neolithic period using rocks such as flint and jadeite.
A blast furnace came into widespread use in France during the mid-15th century for casting cannon. China had utilized this technology since the 4th century BC. Papermaking originated in China during the 2nd century before reaching the Middle East. A group of Chinese papermakers were captured in the 8th century. Technology spread to Europe via the Umayyad conquest of Hispania. A paper mill was established in Sicily in the 12th century. Linen and cotton rags provided fiber for pulp production. Lynn Townsend White Jr credited the spinning wheel with increasing rag supply. Cheap paper became a factor in the development of printing. The stocking frame invented in 1598 increased a knitter's knots per minute from 100 to 1000.
Electrification of factories began gradually in the 1890s after practical DC motors arrived. Growth accelerated between 1900 and 1930 following AC motor introduction. Electricity prices dropped from 1914 to 1917 aiding adoption. Many factories witnessed a 30% increase in output due to electric motors. Ball Brothers Glass Manufacturing Company electrified its mason jar plant in Muncie, Indiana around 1900. New automated processes used glass blowing machines to replace 210 craftsman glass blowers. An electric truck handled 150 dozen bottles at once versus 6 dozen previously. Henry Ford popularized mass production in the late 1910s and 1920s. His company introduced electric motors to chain or sequential production methods. Production of the Ford Model T utilized 32,000 machine tools arranged systematically.
China produced 28.7% of total global manufacturing output in 2023 according to UNIDO data. The United States followed as the second largest manufacturer worldwide. Germany ranked third with an output reaching $844.93 billion in 2023. This marked a 12.25% increase from the previous year. German manufacturing employed approximately 5.5 million people accounting for 20.8% of their workforce. U.S. manufacturing accounted for 10.70% of national output in 2023. Total value reached $2.5 trillion employing 8.41% of the American workforce. Jeff Immelt called for increasing U.S. manufacturing base employment to 20% of the workforce on the 26th of June 2009. Research showed U.S. manufacturing performed poorly compared to other high-wage countries. A total of 3.2 million jobs disappeared between 2000 and 2007 representing one in six positions.
Most manufacturing processes involve significant social and environmental costs today. Clean-up costs of hazardous waste may outweigh product benefits. Hazardous materials expose workers to health risks. Developed countries regulate activity through labor laws and environmental regulations. Manufacturers face pollution taxes to offset environmental costs globally. Tort law and product liability impose additional financial burdens. Environment laws available in developed nations often lack presence in third world economies. Manufacturing-based industries relocated operations to developing-world economies where production costs are significantly lower. The National Institute for Occupational Safety Health recognized manufacturing as a priority industry sector. This designation identifies intervention strategies regarding occupational health and safety issues within the field.

Common questions
When did human ancestors first start making stone tools in Ethiopia's Great Rift Valley?
Human ancestors began striking hard stone cores with hammerstones to create sharp edges at least 2.3 million years ago in Ethiopia's Great Rift Valley. The earliest direct evidence of tool usage dates back 2.5 million years.
How many machine tools were used in the production of the Ford Model T during Henry Ford's mass production era?
Production of the Ford Model T utilized 32,000 machine tools arranged systematically by Henry Ford. His company introduced electric motors to chain or sequential production methods in the late 1910s and 1920s.
What percentage of total global manufacturing output did China produce in 2023 according to UNIDO data?
China produced 28.7% of total global manufacturing output in 2023 according to UNIDO data. Germany ranked third with an output reaching $844.93 billion in 2023 which marked a 12.25% increase from the previous year.
Why do manufacturers face financial burdens related to pollution taxes and product liability today?
Manufacturers face pollution taxes to offset environmental costs globally because most manufacturing processes involve significant social and environmental costs today. Tort law and product liability impose additional financial burdens on companies that expose workers to health risks through hazardous materials.
When was the stocking frame invented and how did it change knitting speed for knitters?
The stocking frame was invented in 1598 and increased a knitter's knots per minute from 100 to 1000. This invention helped cheap paper become a factor in the development of printing alongside linen and cotton rags used for pulp production.
