What is Manufacturing

什么是制造业

制造业发展代写 It is basically a combination of different components used to create an entirely new product. The origins of this word can be traced

Manufacturing is the processing of raw materials to make something new.

It is basically a combination of different components used to create an entirely new product. The origins of this word can be traced back to 1683. With the word being derived from the Latin words manus, and facere, meaning hand and to make respectively.

However, in the modern times, as explained previously. Manufacturing is referred to as the making and producing of products and materials by using different components together and building/ creating an entirely new product. It is usually referred to as this where large scale operations and production is concerned, thereby, ensuring that the end product can be produced in large quantities.

When a raw material is processed it undergoes change, and when one raw material is combined with another, a new product is formed. Once the final product is complete, it has a specific market value . Which is usually much more than the cost of all the materials combined to produce it along with the overheads and other manufacturing costs associated with the production of that particular product.

In this manner, a product is created which not only offers value for money for the customers, but also offers immense profit for the producer as well. There are many organizations which are known for manufacturing, however, these days most of the manufacturing operations are outsourced to countries where the cost of production is considerably lower, thereby, earning greater revenues from economies of scale, while also making use of lower costs.

制造是对原材料进行加工以制造新事物。

它基本上是用于创建全新产品的不同组件的组合。这个词的起源可以追溯到 1683 年。这个词来源于拉丁词 manus 和 facere，分别是手和制造的意思。

然而，在现代，如前所述。制造是指通过将不同的组件一起使用并构建/创造全新产品来制造和生产产品和材料。通常在涉及大规模操作和生产的情况下称为此，从而确保可以大量生产最终产品。

当一种原材料被加工时，它会发生变化，当一种原材料与另一种原材料结合时，就会形成一种新产品。一旦最终产品完成，它就有了特定的市场价值。这通常远远超过生产它的所有材料的成本以及与生产该特定产品相关的间接费用和其他制造成本。

通过这种方式，创造出的产品不仅为客户提供物有所值的服务，而且还为生产商提供了巨大的利润。有许多以制造而闻名的组织，然而，如今大部分制造业务都外包给生产成本相当低的国家，从而从规模经济中获得更多收入，同时也利用了更低的成本。制造业发展代写

History of Manufacturing

The history of manufacturing is quite an interesting process. Where initially products were made by hand, to the point where more and more people were taught the skills required to produce the items in larger quantities, it was eventually taken to the point where machines were introduced to produce for them. This happened when the industrial revolution changed the world.

In the 18^th century, the era of the Industrial Revolution began, which eventually spread far and wide along with the neighboring countries if Germany and France. The manner in which the products were manufactured changed drastically. Industries like textile, glass, mining, and agriculture had undergone an immense change. While previously textile products were hand woven and hand spun, spinning wheels and looms were invented. Which made the cotton production process much easier and smoother. This greatly helped in reducing the time required to produce one product while at the same time significantly reduced the costs related to production. What is interesting to note is that with the introduction of different types of machinery.  The process improved and people learned to use the machines, which made the process easier for them.

制造史

制造业的历史是一个非常有趣的过程。最初的产品是手工制作的，越来越多的人学会了大批量生产所需的技能，最终引入了机器为他们生产。这发生在工业革命改变世界的时候。

18世纪，工业革命时代开始，并最终与邻国德法等国一起广泛传播。产品的制造方式发生了巨大变化。纺织、玻璃、采矿和农业等行业发生了巨大的变化。虽然以前纺织产品是手工编织和手工纺纱，但发明了纺车和织机。这使得棉花生产过程更加容易和顺畅。这极大地帮助减少了生产一种产品所需的时间，同时显着降低了与生产相关的成本。值得注意的是，随着不同类型机器的引入。过程得到改进，人们学会了使用机器，这使他们的过程变得更容易。制造业发展代写

Eli Whitney

The materials that were produced were not only cheaper, but also greater in number. This increased the demand for further manufactured products. The supply on the other hand was low, due to which in 1833, certain laws were introduced to protect the rights of the workers.

However, before this happened. Eli Whitney invented the cotton gin, which allowed cotton to be cleaned far more effectively and efficiently. This way the supply of cotton was increased.  As the farmers were able to provide greater quantities with ease. In turn this raw material became the highest exported product of America.

After a couple of years, Whitney was hired by the governed of the United States of America to make thousands of guns, whereas, previously, they used to be made by hand. Whitney came up with a way which allowed the guns to be produced quickly and cheaply. By using interchangeable parts and leading the country towards mass production. Eventually, many other factories started using and implementing his ideas.  Until the nation’s productivity levels sky rocketed.

Many of the business leaders used these machines to meet the increased demands for further processed products. Which thereby, increased the demand for raw materials even more. The revolution that had come, had its consequences, and many of the machines that Whitney made transformed the manner in which products were manufactured previously. He introduced the concept of mass production to the farmers.  Which was eventually copied by the factory owners as well, and Whitney was tasked with the development of many other machines that could mass produce products in order to meet increasing demand of the customers.

伊莱惠特尼

所生产的材料不仅更便宜，而且数量也更多。这增加了对进一步制造产品的需求。另一方面，供应量很低，因此在 1833 年出台了某些法律来保护工人的权利。

然而，在这之前。 Eli Whitney 发明了轧棉机，可以更有效地清洁棉花。这样一来，棉花的供应就增加了。由于农民能够轻松提供更多数量。反过来，这种原材料成为美国出口最高的产品。

几年后，惠特尼受雇于美利坚合众国的统治者，制造了数千支枪，而以前，它们是手工制造的。惠特尼想出了一种方法，可以快速廉价地生产枪支。通过使用可互换的零件，引领全国走向量产。最终，许多其他工厂开始使用和实施他的想法。直到国家的生产力水平飙升。

许多商业领袖使用这些机器来满足对深加工产品日益增长的需求。从而进一步增加了对原材料的需求。这场革命带来了后果，惠特尼制造的许多机器改变了以前产品的制造方式。他向农民介绍了大规模生产的概念。这最终也被工厂主复制，惠特尼的任务是开发许多其他可以批量生产产品的机器，以满足客户日益增长的需求。制造业发展代写

Thermoplastics and Thermosets

Thermoplastics are those materials that can easily be molded and shaped into anything that a person likes. The official definition is, “the material that softens. When heated above the glass transition temperature or melting temperature and becomes hard after cooling is called thermoplastics.” (NPTEL) They have a special property which allows them to melt when heat is applied to them and similarly allows them to solidify when they are exposed to cold temperatures.

Thermosets on the other hand are those materials which are rigid in their structure. The property of material becoming permanently hard and rigid after cooling when heated above the melting temperature is called thermosets (NPTEL). When a thermoset is heated, it only results in chemical decomposition instead of transformation into a different state.  This means that while thermoplastics can be recycled, thermosets cannot. The molecules of the thermosets are linked together to the point that they are unbreakable.Unless intense temperature is applied to them, and even then, it only decomposes, instead of being transformed in its previous state.

These are some of the differences between thermoplastics and thermosets, as these two differ in terms of properties and molecular structure. It must be noted that there are plenty of materials out there which fall under the category of thermoplastics and thermosets. Many of the polythene bags that are manufactured are thermosets as they cannot be recycled.

热塑性塑料和热固性塑料

热塑性塑料是那些可以很容易地塑造成人们喜欢的任何东西的材料。官方定义是“软化的材料。当加热到玻璃化转变温度或熔化温度以上并在冷却后变硬时，称为热塑性塑料。” (NPTEL) 它们有一种特殊的特性，当加热时它们会熔化，同样地，当它们暴露在寒冷的温度下时，它们会凝固。

另一方面，热固性材料是那些结构刚性的材料。当加热到熔化温度以上时，材料在冷却后变得永久坚硬和刚性的特性称为热固性材料 (NPTEL)。当热固性材料被加热时，它只会导致化学分解，而不是转变为不同的状态。这意味着虽然热塑性塑料可以回收，但热固性塑料不能。热固性塑料的分子连接在一起，牢不可破。除非对它们施加强烈的温度，否则它只会分解，而不是转化为以前的状态。

这些是热塑性塑料和热固性塑料之间的一些区别，因为这两者在性质和分子结构方面有所不同。必须指出的是，有很多材料属于热塑性塑料和热固性塑料。许多制造的聚乙烯袋是热固性塑料袋，因为它们不能回收利用。制造业发展代写
