Effect of Vibration on Mechanical Properties in Sand Casting Process using Organic Binder

Abstract

Casting setups must create the components with a short lead time in today's highly competitive world market. This essential industry now demands defect-free castings with low production costs. Rejection of casted products is caused due to defective components which are influenced by various factors which includes process parameters, all of which can be optimized to improve the quality of the casted products. In this study, an experimental approach was made using vibrated assisted techniques to assess the applicability of the method and improvement of the quality of the casted parts using organic binders in terms of mechanical properties especially the tensile strength, hardness and micro-structure of the products. After investigations, it has been observed that with the influence of vibration frequency at 40 Hz with amplitude 2 V the tensile strength has been improved from 176.60 MPa to 180.81 MPa, hardness improvement from HB33 to HB36 and uniformity in the micro-structure has been observed.
