Design, Fabrication and Testing of Standard Sand Rammer

Abstract

A Standard Sand Rammer was designed, fabricated and its performance compared with an imported one by producing standard specimens from it. The rammer was designed to help foundry industries in Nigeria as well as small-scale foundries acquire basic foundry equipment to test and control raw materials in order to improve castings quality. In designing the standard rammer, standard specification of the American Foundry Society (AFS) was taken into consideration and it followed a systematic design analysis of the basic theories required to make it functional. The standard rammer was fabricated from locally sourced materials, tested and found to produce a cylindrical specimen of 50mm by 50mm after three rams. Flowability and Permeability tests were carried out on specimens produced from the Rammer. These shows similar results compared with an imported rammer.
