Abstract: A recent study conducted by the authors, recording on site observations and grading responses to questionnaires by the 1 to 5 according to the Likert scale indicates that the gating practice in the foundries of research institutions and tertiary institutions in Lagos state is far from the best global practice. Some common errors, such as lack of knowledge and application of the critical flow velocity of the molten metal, prevention of flow stoppage across extensive horizontal planes with consequential non uniform liquid front. Lack of knowledge of the best types of pouring basins to use, Lack of knowledge on general filter types and usages among others were identified. This paper provides simple but highly effective solutions that do not warranty the purchase of new facilities. It is important to advance the knowledge of our training institutes especially as they are responsible for the training of our present and future foundry work force.. The capability of our foundries is improved by the quality of the work force and this paper is hoped will contribute in no small measure to the capability of our foundries by improving the know-how of the work force.
