... in South Africa. The republic of South Africa has important engineering and manufacturing sectors. They are the strongest on the whole African continent. South Africans have shown some skill, when it came to mining, minerals processing, artificial fuel production and many other fields. 

manufacturing for example food manufacturing or machine manufacturing. To make clothing there is textiles manufacturing and to get raw materials we do chemical manufacturing. With a touch of class we can achieve world manufacturing. When someone else does it, it is called contract manufacturing. On a larger scale it is  industrial manufacturing. With rubber and polimeers we call it  plastic manufacturing. To put it into containers, cans or bags is  packaging manufacturing. Making medicine and herbs. pharmaceutical manufacturing,

For designing what to make one needs engineering. Those buildings are designed through civil engineering befor building and construction. The machines and their components owe their existence to mechanical engineering, while chemical engineering designs chemicals and processes. To get power going one uses electrical engineering. And process to make it happen are done via industrial engineering. The raw materials from the soil are best get via mining engineering. While metallurgical engineering helps us to extract metals from the ore. Out calculations and information processing is best provided for by computer engineering. And overall it is manufacturing engineering that makes everything effective. The earth can be used better engineering geotechnical that gets things going. And engineering drawings are best provide for by professional engineering firms. They the provide them to manufacturing companies which are a  business that again requires certain services services. With engineering tenders one can get to be apply technology which we learn from books.
