In Zambia it is estimated that the existing housing stock stands at 2.5 million units catering for about 16 million people. The national housing deficit stands at more than 2 million houses and is compounded by urbanisation. Efforts have so far been made to use alternative building technology...

Thirty four out of forty (85%) TAZARA Diesel Electric (DE) locomotives were operating with either defective or no speedometer system at all. This compromised the safety of locomotives and peoples’ lives. As a result of financial challenges, TAZARA was unable buy new DE speedometer system costing...

In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...

China‟s use of Special Economic Zones (SEZs) to spur its remarkable economic development was seen as the way to go, particularly for least developing economies. Zambia, like most African countries, has established these zones with the help of the Chinese. In Zambia, the zones are called...

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties changing and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming operations. Traditionally, experimental trial and...

This research work was to provide a locally produced electric motor to drive the UNZA pump.The work was carried out by using the UNZA pump parameters and electric motor material from published works on the electric motor design and manufacture and real experience from examining electric motors in...

The Zambian economy in 1964 was among the strongest in Sub-Saharan Africa. Through the years, however, it declined to among the weakest. The manufacturing sector's contribution to GDP declined from a peak of 30 per cent in 1992 to 24 per cent in 1996. The engineering manufacture sub-sector...

The economic advancement of any country depends on its ability to add value (through manufacturing) to its available local raw material resources. Zambia for a long time has been exporting copper as a raw material and importing finished copper products. This economic situation deprives Zambia of...

There has been an accelerated use of Computer Numerical Control machine tools by developed countries over the past decade resulting in manufacturing companies becoming more competitive on the world market. However, the initial cost of these machines is prohibitive to many companies in the third...

Pumps, of varying designs, have historically been vital in fluid flow. In Zambia, typical applications could be found in domestic water supplies and industrial applications. Complete pumping units have been designed and manufactured elsewhere. The manufacture of pumps in Zambia has generally...
