Abstract
The increasing use of non-ferrous metals for more sophisticated application has led to the ever greater demands for major improvement in the quality of foundry products. Quality control reduces reject and increase production in a foundry. Use of high standard equipment, technique and competitive workforce result in good quality products. A survey was conducted with the aim of assessing the level of quality control and categorising the local foundries in Mubi. A total of seven foundries located in Tsamiya, Wuro-patuji, Kwacham, Wuro-gude, Lamorde, Federal Polytechnic Mubi and Gaya were studied. These foundries were using aluminium scrap as a raw material. Data was gathered by use of questionnaires, interviews and site visit to foundries. The foundries were classified into small scale foundries, medium scale foundries and large scale foundries. This classification was based on a parameter which focused on human resources, capital investment, and volume of scrap consumed, energy consumed, safety and environmental conservation. The result of the survey shows that the quality control practices such as chemical analysis, material testing and melt treatment (use of additives, degasser and fluxes) were not implemented in six foundry shops. It was also discovered that 53.3 percent of the workforce lacked formal training in foundry practices and the highest capital utilization was about 33.6 percent. This has led to low quality product with no competitive edge in the market.
