Design and Development of a Stirrer Set-up by using Drill Machine for Existing Resistance Coil Furnace

This paper presents the design and development of a stirrer set-up for an existing resistance coil furnace, aimed at producing metal matrix composites (MMCs). In conventional stir casting systems, electric motors are typically used for stirring. However, these motors are often expensive and require additional components like speed control systems, belt-pulley arrangements, or gear trains, which increase both cost and system weight. To address these issues, this study proposes the use of a portable drill machine as an alternative stirring device. The drill machine offers a cost-effective and lightweight solution with a simplified design. The developed stirrer set-up mainly consists of a drill machine (as the motor), a stirrer blade and rod, a supporting frame, and clamps for secure mounting. This innovative approach provides an optimized and economical design for small-scale composite manufacturing. Through careful material selection, prototyping, and economic analysis, this study aims to demonstrate the technical feasibility and cost-effectiveness of the stirrer retrofit system. By providing a sustainable alternative to equipment replacement, the project contributes to the advancement of composite manufacturing capabilities in resource-limited environments.
