It is also a common name for these Mongolian places: Darkhan-Uul Province , an aimag (province) Darkhan (city) , the capital of Darkhan-Uul Province Darkhan, Khentii , a sum (district) of the Khentii aimag Darhan Muminggan United Banner ,
150-405: A blue-collar work ethic, are accessible to the general public, and are constructed from materials with histories that exceed the boundaries of Western "fine art" tradition, such as ceramics , glass , textiles , metal and wood . These products are produced within a specific community of practice , and while they mostly differ from the products produced within the communities of art and design,
225-403: A 30% increase in output simply from changing over to electric motors. Electrification enabled modern mass production, as with Thomas Edison's iron ore processing plant (about 1893) that could process 20,000 tons of ore per day with two shifts, each of five men. At that time it was still common to handle bulk materials with shovels, wheelbarrows and small narrow-gauge rail cars, and for comparison,
300-643: A backbone "main" assembly line. A diagram of a typical mass-production factory looks more like the skeleton of a fish than a single line. Vertical integration is a business practice that involves gaining complete control over a product's production, from raw materials to final assembly. In the age of mass production, this caused shipping and trade problems in that shipping systems were unable to transport huge volumes of finished automobiles (in Henry Ford's case) without causing damage, and also government policies imposed trade barriers on finished units. Ford built
375-585: A canal digger in previous decades typically handled five tons per 12-hour day. The biggest impact of early mass production was in manufacturing everyday items, such as at the Ball Brothers Glass Manufacturing Company , which electrified its mason jar plant in Muncie, Indiana , U.S., around 1900. The new automated process used glass-blowing machines to replace 210 craftsman glass blowers and helpers. A small electric truck
450-403: A company to produce a larger quantity of one product at a lower cost than using traditional, non-linear methods. However, mass production is inflexible because it is difficult to alter a design or production process after a production line is implemented. Also, all products produced on one production line will be identical or very similar, and introducing variety to satisfy individual tastes

Following World War II, in the United States, William Levitt pioneered the building of standardized tract houses in 56 different locations around the country. These communities were dubbed Levittowns , and they were able to be constructed quickly and cheaply through
675-566: A few words of common tourist languages. There are also specialty markets such as: According to the Vietnam Handicrafts Export Association (VIETCRAFT), Vietnam's handicrafts export turnover in 2023 reached US$ 2.2 billion, up 10.5% over 2022. The United States is Vietnam's largest export market, accounting for 35% of total export turnover. Vietnam's handicrafts industry currently has about 600 villages, with over 10 million direct workers. Wickerwork
750-564: A handcrafted item is the paramount criterion; those made by mass production or machines are not handicraft goods. Seen as developing the skills and creative interests of students, generally and sometimes towards a particular craft or trade, handicrafts are often integrated into educational systems, both informally and formally. Most crafts require the development of skill and the application of patience but can be learned by virtually anyone. Like folk art , handicraft output often has cultural and/or religious significance, and increasingly may have
825-463: A multiple head milling machine that could simultaneously machine 15 engine blocks held on a single fixture. All of these machine tools were arranged systematically in the production flow and some had special carriages for rolling heavy items into machining position. Production of the Ford Model T used 32,000 machine tools. The process of prefabrication, wherein parts are created separately from

#1732794264072900-538: A political message as well, as in craftivism . Many crafts become very popular for brief periods of time (a few months, or a few years), spreading rapidly among the crafting population as everyone emulates the first examples, then their popularity wanes until a later resurgence. The Arts and Crafts movement originated as a late-19th-century design reform and social movement principally in Europe, North America and Australia, and continues today. Its proponents are motivated by
975-661: A short period of time. Handicraft production is a small–scale production of products using manual labor. It was especially common in the Middle Ages , during the era of the Industrial Revolution it was mainly supplanted by mass production , however, it still exists for the production of goods such as luxury goods . The "handmade effect" is a phenomenon where consumers exhibit a preference for products that are crafted by human labor rather than produced through automated or robotic processes . This preference
1050-513: A spindle cutting machine, which could produce multiple parts at the same time. Terry hired Silas Hoadley and Seth Thomas to work the Assembly line at the facilities. The Porter Contract was the first contract which called for mass production of clock movements in history. In 1815, Terry began mass-producing the first shelf clock. Chauncey Jerome , an apprentice of Eli Terry mass-produced up to 20,000 brass clocks annually in 1840 when he invented
1125-591: A system of process control which uses various instruments to measure variables such as temperature, pressure, volumetric and level, providing feedback. Bulk materials such as coal, ores, grains and wood chips are handled by belt, chain, slat, pneumatic or screw conveyors, bucket elevators and mobile equipment such as front-end loaders . Materials on pallets are handled with forklifts. Also used for handling heavy items like reels of paper, steel or machinery are electric overhead cranes , sometimes called bridge cranes because they span large factory bays. Mass production
1200-401: A tremendous amount of useless handling and hauling. The belt and line shaft were also tremendously wasteful – so wasteful indeed that no factory could be really large, for even the longest line shaft was small according to modern requirements. Also high speed tools were impossible under the old conditions – neither the pulleys nor the belts could stand modern speeds. Without high speed tools and
1275-480: A very large amount of trees. In order to speed up such efforts, fast propagation of trees may be useful. Some automated machines have been produced to allow for fast (vegetative) plant propagation . Also, for some plants that help to sequester carbon (such as seagrass ), techniques have been developed to help speed up the process . Mass production benefited from the development of materials such as inexpensive steel, high strength steel and plastics. Machining of metals
1350-607: A worker work on a whole product from start to finish. The emergence of mass production allowed supply to outstrip demand in many markets, forcing companies to seek new ways to become more competitive . Mass production ties into the idea of overconsumption and the idea that we as humans consume too much. Mass production of fluid matter typically involves piping with centrifugal pumps or screw conveyors (augers) to transfer raw materials or partially complete products between vessels. Fluid flow processes such as oil refining and bulk materials such as wood chips and pulp are automated using
1425-656: Is Jikji , printed in Korea in the year 1377. Johannes Gutenberg , through his invention of the printing press and production of the Gutenberg Bible , introduced movable type to Europe. Through this introduction, mass production in the European publishing industry was made commonplace, leading to a democratization of knowledge , increased literacy and education, and the beginnings of modern science . French artillery engineer Jean-Baptiste de Gribeauval introduced
1500-405: Is capital-intensive and energy-intensive, for it uses a high proportion of machinery and energy in relation to workers. It is also usually automated while total expenditure per unit of product is decreased. However, the machinery that is needed to set up a mass production line (such as robots and machine presses ) is so expensive that in order to attain profits there must be some assurance that
1575-448: Is a reduction of non-productive effort of all types. In craft production , the craftsman must bustle about a shop, getting parts and assembling them. He must locate and use many tools many times for varying tasks. In mass production, each worker repeats one or a few related tasks that use the same tool to perform identical or near-identical operations on a stream of products. The exact tool and parts are always at hand, having been moved down

1800-406: Is driven, in large part, by the perception that handmade products symbolically "contain love ." The handmade effect is influenced by two key factors. Firstly, consumers express stronger intentions to purchase handmade products when buying gifts for loved ones, compared to more distant recipients. Secondly, they are willing to pay a higher price for handmade gifts when the purchase is motivated by
1875-599: Is explained not only by economic and natural–geographical factors, but also by the support and encouragement of the handicraft industry from the state. There are almost as many variations on the theme of handicrafts as there are crafters with time on their hands, but they can be broken down into a number of categories: Handicrafts are often made for home use and decor. If sold, they are sold in direct sales , gift shops , public markets , and online shopping . In developing countries, handicrafts are sold to locals and as souvenirs to tourists. Sellers tend to speak at least
1950-536: Is in fact as practical as it is aesthetic. Handicraft has its roots in the rural crafts —the material-goods necessities—of ancient civilizations, and many specific crafts have been practiced for centuries, while others are modern inventions or popularizations of crafts which were originally practiced in a limited geographic area. Many handcrafters use natural, even entirely indigenous, materials while others may prefer modern, non-traditional materials, and even upcycle industrial materials. The individual artisanship of
2025-506: Is particularly pronounced for products with higher symbolic value, where expressing one's beliefs and personality holds greater significance. Consumers , especially in contexts emphasizing symbolic consumption, have a stronger motivation for uniqueness and associate human labor more closely with product uniqueness. In product categories where mechanical production is common, consumers are more attracted to products labeled as handmade. The positive handmade effect on product attractiveness
2100-524: Is that while Taylor focused mostly on efficiency of the worker, Ford also substituted for labor by using machines, thoughtfully arranged, wherever possible. In 1807, Eli Terry was hired to produce 4,000 wooden movement clocks in the Porter Contract. At this time, the annual yield for wooden clocks did not exceed a few dozen on average. Terry developed a milling machine in 1795, in which he perfected Interchangeable parts . In 1807, Terry developed
2175-514: Is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines . Together with job production and batch production , it is one of the three main production methods. The term mass production was popularized by a 1926 article in the Encyclopædia Britannica supplement that was written based on correspondence with Ford Motor Company . The New York Times used
2250-620: The Ford River Rouge Complex with the idea of making the company's own iron and steel in the same large factory site where parts and car assembly took place. River Rouge also generated its own electricity. Upstream vertical integration, such as to raw materials, is away from leading technology toward mature, low-return industries. Most companies chose to focus on their core business rather than vertical integration. This included buying parts from outside suppliers, who could often produce them as cheaply or cheaper. Standard Oil ,
2325-560: The Henry Ford Company which was rebranded as Cadillac and later was awarded the Dewar Trophy in 1908 for creating interchangeable mass-produced precision engine parts, Henry Ford downplayed the role of Taylorism in the development of mass production at his company. However, Ford management performed time studies and experiments to mechanize their factory processes, focusing on minimizing worker movements. The difference

2400-445: The Industrial Revolution by many centuries; however, it was not until the introduction of machine tools and techniques to produce interchangeable parts were developed in the mid-19th century that modern mass production was possible. Mass production involves making many copies of products, very quickly, using assembly line techniques to send partially complete products to workers who each work on an individual step, rather than having
2475-664: The Portsmouth Block Mills in England to make ships' pulley blocks for the Royal Navy in the Napoleonic Wars . It was achieved in 1803 by Marc Isambard Brunel in cooperation with Henry Maudslay under the management of Sir Samuel Bentham . The first unmistakable examples of manufacturing operations carefully designed to reduce production costs by specialized labour and the use of machines appeared in
2550-643: The Venetian Arsenal produced nearly one ship every day in what was effectively the world's first factory , which at its height employed 16,000 people. The invention of movable type has allowed for documents such as books to be mass produced. The first movable type system was invented in China by Bi Sheng , during the reign of the Song dynasty , where it was used to, among other things, issue paper money . The oldest extant book produced using metal type
2625-488: The guild system. Adolescents were apprenticed to a master craftsman and refined their skills over a period of years in exchange for low wages. By the time their training was complete, they were well equipped to set up in trade for themselves, earning their living with the skill that could be traded directly within the community, often for goods and services. The Industrial Revolution and the increasing mechanization of production processes gradually reduced or eliminated many of
2700-408: The market . Mostly these were household products: dishes, furniture, jewelry, souvenirs, clothes, shoes. However, over time, other goods, such as weapons , began to go on sale. In pre–revolutionary Russia , handicraft production was quite widespread: about 30% of all manufactured products were produced by handicraft methods. Products were sold at fairs , and barter exchange was widespread. With
2775-480: The 18th century in England. The Navy was in a state of expansion that required 100,000 pulley blocks to be manufactured a year. Bentham had already achieved remarkable efficiency at the docks by introducing power-driven machinery and reorganising the dockyard system. Brunel, a pioneering engineer, and Maudslay, a pioneer of machine tool technology who had developed the first industrially practical screw-cutting lathe in 1800 which standardized screw thread sizes for
2850-455: The 20th century's definition of mass production appeared in a 1926 Encyclopædia Britannica supplement. The article was written based on correspondence with Ford Motor Company and is sometimes credited as the first use of the term. Electrification of factories began very gradually in the 1890s after the introduction of a practical DC motor by Frank J. Sprague and accelerated after the AC motor
2925-601: The Emperor's tomb is also believed to have been created through the use of standardized molds on an assembly line . In ancient Carthage , ships of war were mass-produced on a large scale at a moderate cost, allowing them to efficiently maintain their control of the Mediterranean . Many centuries later, the Republic of Venice would follow Carthage in producing ships with prefabricated parts on an assembly line:
3000-476: The armories designing and building many of their own. Some of the methods employed were a system of gauges for checking dimensions of the various parts and jigs and fixtures for guiding the machine tools and properly holding and aligning the work pieces. This system came to be known as armory practice or the American system of manufacturing , which spread throughout New England aided by skilled mechanics from
3075-894: The armories who were instrumental in transferring the technology to the sewing machines manufacturers and other industries such as machine tools, harvesting machines and bicycles. Singer Manufacturing Co. , at one time the largest sewing machine manufacturer, did not achieve interchangeable parts until the late 1880s, around the same time Cyrus McCormick adopted modern manufacturing practices in making harvesting machines . During World War II , The United States mass-produced many vehicles and weapons , such as ships (i.e. Liberty Ships , Higgins boats ), aircraft (i.e. North American P-51 Mustang , Consolidated B-24 Liberator , Boeing B-29 Superfortress ), jeeps (i.e. Willys MB ), trucks, tanks (i.e. M4 Sherman ) and M2 Browning and M1919 Browning machine guns . Many vehicles, transported by ships have been shipped in parts and later assembled on-site. For

3150-504: The assembly line consecutively. The worker spends little or no time retrieving and/or preparing materials and tools, and so the time taken to manufacture a product using mass production is shorter than when using traditional methods. The probability of human error and variation is also reduced, as tasks are predominantly carried out by machinery; error in operating such machinery has more far-reaching consequences. A reduction in labour costs, as well as an increased rate of production, enables
3225-652: The beginning of industrialisation and collectivization of the Soviet Union, the handicraft mode of production was declared "the highest degree of oppression of the working people" and ceased to exist in almost all spheres of the Soviet economy except on an informal basis. Some state economies, such as that of Vietnam , are largely based on handicraft production. For example, in the 1950s in North Vietnam , there were more than 100,000 handicraft enterprises. In
3300-429: The blocks to ensure alignment throughout the process. One of the many advantages of this new method was the increase in labour productivity due to the less labour-intensive requirements of managing the machinery. Richard Beamish, assistant to Brunel's son and engineer, Isambard Kingdom Brunel , wrote: So that ten men, by the aid of this machinery, can accomplish with uniformity, celerity and ease, what formerly required
3375-477: The boundaries often overlap, resulting in hybrid objects. Additionally, as the interpretation and validation of art is frequently a matter of context, an audience may perceive handcrafted objects as art objects when these objects are viewed within an art context, such as in a museum or in a position of prominence in one's home. Simple "arts and crafts" projects are a common elementary and middle school activity in both mainstream and alternative education systems around
3450-407: The cheap 30-hour OG clock. The United States Department of War sponsored the development of interchangeable parts for guns produced at the arsenals at Springfield, Massachusetts and Harpers Ferry , Virginia (now West Virginia) in the early decades of the 19th century, finally achieving reliable interchangeability by about 1850. This period coincided with the development of machine tools , with
3525-402: The desire to convey love rather than simply acquiring the best-performing product. The handicraft method of production has been used by people since ancient times. Initially, people engaged in handicraft production aimed to satisfy the needs of their own economy, however, with the development of commodity–money relations , an increasing number of goods produced by them began to be supplied to
3600-528: The early 1970s, even before the end of the war , handicraft production provided about half of all the products of the local industry and almost a third of the total industrial production of the republic. By 1977, after the reunification of Vietnam, there were 700,000 handicraftsmen in South Vietnam . Handicraft production in Nepal withstands competition with industrial production and foreign goods, which
3675-456: The fashion industry, particularly in the realm of fibers and materials. The advent of synthetic fibers, such as polyester and nylon, revolutionized textile manufacturing by providing cost-effective alternatives to natural fibers. This shift enabled the rapid production of inexpensive clothing, contributing to the rise of fast fashion. This reliance on mass production has raised concerns about environmental sustainability and labor conditions, spurring
3750-502: The finer steels which they brought about, there could be nothing of what we call modern industry. Mass production was popularized in the late 1910s and 1920s by Henry Ford's Ford Motor Company , which introduced electric motors to the then-well-known technique of chain or sequential production. Ford also bought or designed and built special purpose machine tools and fixtures such as multiple spindle drill presses that could drill every hole on one side of an engine block in one operation and
3825-559: The finished product, is at the core of all mass-produced construction. Early examples include movable structures reportedly utilized by Akbar the Great , and the chattel houses built by emancipated slaves on Barbados . The Nissen hut , first used by the British during World War I , married prefabrication and mass production in a way that suited the needs of the military. The simple structures, which cost little and could be erected in just

#17327942640723900-471: The first instance of the application of mass production techniques (though not necessarily the assembly-line method) to marine engineering. In filling an Admiralty order for 90 sets to his high-pressure and high-revolution horizontal trunk engine design, Penn produced them all in 90 days. He also used Whitworth Standard threads throughout. Prerequisites for the wide use of mass production were interchangeable parts , machine tools and power , especially in
3975-594: The first time which in turn allowed the application of interchangeable parts , collaborated on plans to manufacture block-making machinery. By 1805, the dockyard had been fully updated with the revolutionary, purpose-built machinery at a time when products were still built individually with different components. A total of 45 machines were required to perform 22 processes on the blocks, which could be made into one of three possible sizes. The machines were almost entirely made of metal thus improving their accuracy and durability. The machines would make markings and indentations on
4050-475: The form of electricity . Some of the organizational management concepts needed to create 20th-century mass production, such as scientific management , had been pioneered by other engineers (most of whom are not famous, but Frederick Winslow Taylor is one of the well-known ones), whose work would later be synthesized into fields such as industrial engineering , manufacturing engineering , operations research , and management consultancy . Although after leaving
4125-507: The ideals of movement founders such as William Morris and John Ruskin , who proposed that in pre-industrial societies, such as the European Middle Ages , people had achieved fulfillment through the creative process of handicrafts. This was held up in contrast to what was perceived to be the alienating effects of industrial labor. These activities were called crafts because originally many of them were professions under
4200-547: The invention of machine tools the manufacture of precision parts, especially metal ones, was highly labour-intensive. Crossbows made with bronze parts were produced in China during the Warring States period . The Qin Emperor unified China at least in part by equipping large armies with these weapons, which were fitted with a sophisticated trigger mechanism made of interchangeable parts. The Terracotta Army guarding
4275-423: The leather belt and line shaft , for it eventually became possible to provide each tool with its own electric motor. This may seem only a detail of minor importance. In fact, modern industry could not be carried out with the belt and line shaft for a number of reasons. The motor enabled machinery to be arranged in the order of the work, and that alone has probably doubled the efficiency of industry, for it has cut out
4350-455: The leveraging of economies of scale , as well as the specialization of construction tasks in a process akin to an assembly line. This era also saw the invention of the mobile home , a small prefabricated house that can be transported cheaply on a truck bed. In the modern industrialization of construction, mass production is often used for prefabrication of house components. Fabrics and Materials Mass production has significantly impacted
4425-793: The major oil company in the 19th century, was vertically integrated partly because there was no demand for unrefined crude oil, but kerosene and some other products were in great demand. The other reason was that Standard Oil monopolized the oil industry. The major oil companies were, and many still are, vertically integrated, from production to refining and with their own retail stations, although some sold off their retail operations. Some oil companies also have chemical divisions. Lumber and paper companies at one time owned most of their timber lands and sold some finished products such as corrugated boxes. The tendency has been to divest of timber lands to raise cash and to avoid property taxes. The economies of mass production come from several sources. The primary cause
4500-583: The materials that surround us for economical, cultural and environmental purposes. Secondary schools and college and university art departments increasingly provide elective options for more handicraft-based arts, in addition to formal " fine arts ", a distinction that continues to fade throughout the years, especially with the rise of studio craft , i.e. the use of traditional handicrafts techniques by professional fine artists. Many community centers and schools run evening or day classes and workshops, for adults and children, offering to teach basic craft skills in
4575-457: The need for greater ethical and sustainable practices within the fashion industry. Mass production systems for items made of numerous parts are usually organized into assembly lines . The assemblies pass by on a conveyor, or if they are heavy, hung from an overhead crane or monorail. In a factory for a complex product, rather than one assembly line, there may be many auxiliary assembly lines feeding sub-assemblies (i.e. car engines or seats) to

The term arts and crafts is also applied, especially in the United States and mostly to hobbyists' and children's output rather than items crafted for daily use, but this distinction is not formal, and the term is easily confused with the Arts and Crafts design movement, which
4725-612: The oldest handicraft is Dhokra ; this is a sort of metal casting that has been used in India for over 5,000 years and is still used. In Iranian Baluchistan , women still make red ware hand-made pottery with dotted ornaments, much similar to the 4,000-year-old pottery tradition of Kalpurgan, an archaeological site near the village. Usually, the term is applied to traditional techniques of creating items (whether for personal use or as products) that are both practical and aesthetic. Handicraft industries are those that produce things with hands to meet

It had already been checked that the finished part would be to specifications to fit all the other finished parts—and it would be made more quickly, with no time spent on finishing the parts to fit one another. Later, once computerized control came about (for example, CNC ), jigs were obviated, but it remained true that
4950-421: The product will be successful. One of the descriptions of mass production is that "the skill is built into the tool", which means that the worker using the tool may not need the skill. For example, in the 19th or early 20th century, this could be expressed as "the craftsmanship is in the workbench itself" (not the training of the worker). Rather than having a skilled worker measure every dimension of each part of

The term handicrafts can also refer to the products themselves of such artisanal efforts, that require specialized knowledge, maybe highly technical in their execution, require specialized equipment and/or facilities to produce, involve manual labor or
5100-418: The skill (or knowledge) was built into the tool (or process, or documentation) rather than residing in the worker's head. This is the specialized capital required for mass production; each workbench and set of tools (or each CNC cell, or each fractionating column ) is different (fine-tuned to its task). Standardized parts and sizes and factory production techniques were developed in pre-industrial times; before

He streamlined production and management of cannonballs and cannons by limiting them to only three calibers, and he improved their effectiveness by requiring more spherical ammunition. Redesigning these weapons to use interchangeable wheels, screws, and axles simplified mass production and repair. In the Industrial Revolution , simple mass production techniques were used at
5250-520: The term in the title of an article that appeared before the publication of the Britannica article. The idea of mass production is applied to many kinds of products: from fluids and particulates handled in bulk ( food , fuel , chemicals and mined minerals ), to clothing, textiles, parts and assemblies of parts ( household appliances and automobiles ). Some mass production techniques, such as standardized sizes and production lines, predate
5325-513: The uncertain labour of one hundred and ten. By 1808, annual production from the 45 machines had reached 130,000 blocks and some of the equipment was still in operation as late as the mid-twentieth century. Mass production techniques were also used to rather limited extent to make clocks and watches, and to make small arms, though parts were usually non-interchangeable. Though produced on a very small scale, Crimean War gunboat engines designed and assembled by John Penn of Greenwich are recorded as

In some of the Scandinavian or Nordic countries, more advanced handicrafts form part of the formal, compulsory school curriculum, and are collectively referred to as slöjd in Swedish, and käsityö in Finnish. Students learn how to work mainly with metal, textile and wood, not for professional training purposes as in American vocational–technical schools , but with the aim to develop children's and teens' practical skills, such as everyday problem-solving ability, tool use, and understanding of
5475-667: Was developed by Galileo Ferraris , Nikola Tesla and Westinghouse , Mikhail Dolivo-Dobrovolsky and others. Electrification of factories was fastest between 1900 and 1930, aided by the establishment of electric utilities with central stations and the lowering of electricity prices from 1914 to 1917. Electric motors were several times more efficient than small steam engines because central station generation were more efficient than small steam engines and because line shafts and belts had high friction losses. Electric motors also allowed more flexibility in manufacturing and required less maintenance than line shafts and belts. Many factories saw
5550-605: Was greatly enhanced with high-speed steel and later very hard materials such as tungsten carbide for cutting edges. Fabrication using steel components was aided by the development of electric welding and stamped steel parts, both which appeared in industry in about 1890. Plastics such as polyethylene , polystyrene and polyvinyl chloride (PVC) can be easily formed into shapes by extrusion , blow molding or injection molding , resulting in very low cost manufacture of consumer products, plastic piping, containers and parts.
