Injection moulding is a manufacturing process used to produce parts by injecting molten material into a mould. It is widely used for the mass production of plastic parts, and India has become a significant player in this field due to its growing manufacturing sector. This essay explores the current practices in injection moulding in India, covering various aspects such as industry overview, technological advancements, materials used, and challenges faced by the industry.   Industry Overview   India's injection moulding industry has experienced substantial growth over the past few decades. The increasing demand for plastic products across various sectors such as automotive, electronics, healthcare, packaging, and consumer goods has fuelled this growth. The industry's expansion is also supported by favourable government policies, foreign direct investments, and the rise of domestic manufacturers.   The Indian injection moulding market is characterized by a mi...

 Use of Plastic in Agriculture in India I was request from many visitors to give detail of plastic in agriculture. So, I thought it would be good to write which will help Indian former to understand the use of plastic. Below is little help that will give some help to understand the use of plastic and its benefits. Plastic has become an integral part of modern agriculture, transforming traditional practices and offering numerous benefits that contribute to increased productivity and efficiency. In India, where agriculture forms a significant part of the economy and provides livelihood to a large segment of the population, the use of plastic in agriculture has gained substantial traction. This note delves into the various aspects of plastic usage in Indian agriculture, highlighting its applications, benefits, challenges, and sustainable practices.  Applications of Plastic in Indian Agriculture 1. **Mulching** : Plastic mulching involves covering the soil with plastic films to...

Polymers are difficult to classify because there are so many interacting relationship among the large number of polymeric materials now in existence. Four most methods of classifications are 1.        Physico chemical structure 2.        Mode reparation 3.        Physical properties 4.        Technical applications   A.       Physico Chemical structure                 Functionality: - The ultimate result of coupling monomers to produce polymers is wholly dependent on the functionality of monomer. Molecule is called Mono-, bi-,tri-, or polyfunctional depending on the number of reactive bonds or groups available for coupling at beginning or during course of polymeric reaction. 1.        Unifunctional   (U-), Exampl...

Polymeric materials consist of molecules of higher molecular weight, varying from 10 3 to 10 7 . All polymer have recurring structural molecular units that comprises large molecules. Four major industries 1.        Plastic 2.        Fibre 3.        Rubber and 4.        Paint and Varnish. Naturally occurring polymers are a) Cellulose b) Lignin C) Proteins and d) Resins and rubbers. On account of their inherent advantage in properties and versatility in adaptation and use, Plastic have come to play vital role in variety of application in world over Plastics are used in making essential consumers goods of daily use for common man such as Basket, water bottle, tiffin box, toothbrushes. They also find application in field like agriculture, automobile, transportation, engineering, electronics, defense, medicine and building construction. Plastic is growing impo...

Single Use Plastic Ban. There is always confusion about single use plastic ban. Being an entrepreneur I had been asked what type of single use plastic is banned by Govt. So I think to make it clear what type single use plastic is banned.  There is always problem with waste disposable plastic. Problem includes 1.        Accumulation of plastic in Land fills, water bodies, 2.        Burning such waste in open environment causes various diseases in humans and animals. 3.        Clogging drains and Nallas causing flood in urban Cities 4.        Micro plastic are having negative impacts on fish diversity and fisheries activity. 5.        Leaching of chemical from plastic affecting fertility of soil. To avoid such incident and problems, maharastra Govt has banned below listed of single use plastic. v   Manufacture, usage, transport, di...
