  • V Singh


Kolfe House-Hold Utensil Factory in Addis Ababa, is producing different types of utensils for house-hold use from commercial aluminium. Deep drawing or/and  spinning are the methods used for shaping this metal to desired shape and size, though some small parts are cast too. One of their products is kettle, which is produced by deep drawing the aluminium discfollowed by spinning. The spinning chuck is made of wood. The problem put forward to the investigator was the short span of life of this chuck, though the rough surface finish of the kettles was also observed and taken as another problem. Investigations were carried out at each stage of processing. 1Jie suggestions made, after experimental results, not only solve the problems, if incorporated, but also increase the production few fold times with increased financial gains.
