Design and Development of a Rubber Component Deflashing Machine for Small Scale Production

Abstract

The rubber molding industry frequently encounters the challenge of removing excess material, known as flash, from molded components. Manual deflashing methods are labor-intensive, time-consuming, and often result in inconsistent product quality, particularly for small-scale manufacturing units with limited resources. This research presents the design and development of a cost-effective, semi-automatic pneumatic deflashing machine specifically engineered for small-scale rubber component production.

The proposed machine integrates a robust metal frame structure, a pneumatic cylinder for controlled actuation, a push-button valve for operator control, and a custom-designed cutting die tailored to specific rubber component geometries. The methodology encompassed comprehensive mechanical design, pneumatic system integration, and rigorous performance testing against traditional manual deflashing techniques.

Experimental results demonstrate that the developed machine achieves significant reductions in cycle time, improves deflashing consistency, and enhances overall product quality while maintaining operational simplicity and affordability. The findings indicate that this semi-automatic approach offers an optimal balance between manual labor and fully automated cryogenic systems, making it highly suitable for small and medium enterprises (SMEs) in the rubber manufacturing sector.
