Manufacturing sector has played a peripheral role in Uganda’s market-driven growth
trajectory. The share of manufacturing in GDP improved from 6.3% in 1982 to 8.4% in
1997. Thereafter, it declined to about 7 percent, this falls below the average of 11% for least
developed countries (UNCTAD 2008: 7).Moreover, manufacturing activities are either of the
end-product assembling type or food processing both of which are characterized by low
value added manufacturing.
The sector can be classified by the level of production that is to say primary, secondary,
tertiary, and quaternary and quinary sector. The primary industrial sector of the economy
extracts products from nature inclusive of raw materials such as food and cash crops, fish,
timber and mineral ores. Secondary sector encompasses value addition in line with
manufacturing, processing, and construction. Metal works and smelting, automobile
production, energy utilities, engineering construction among others dominate the secondary
sector (Manufacturing, n.d.). Tertiary sector largely conforms to provision of services like
banking, media, and law together with Quaternary sector that executes intellectually
dependent activities, libraries, scientific research, education, and information technology.
Although growing, the Secondary sector is faced by a number of challenges such as high
costs of electricity, strong competition from imported products and relatively high poverty
levels that directly impact on the purchasing power of the domestic market. (Spate & Lear

Metal casting processes today have become integral to manufacturing industry and can be
used to create complex geometric parts with comparative ease, irrespective of the part sizing.
Cast metal products are found in 90% of manufactured goods and equipment ranging from
critical components for the aviation and automobile industry to home appliances and surgical
equipment.
The major forms of casting employed include Sand casting (use of green sand to make
moulds into which the molten metal is poured and solidifies), investment casting (entails the
coating of a wax pattern with refractory material, thereafter the wax is melted out forming a
mould) and die casting. Die casting is one of the most economical casting processes for the 2
manufacturing of precision shaped parts facilitating mass production with premium quality,
low cost and low weight (M.Sowmya1, 2014)
