“…It is due to their capability of producing near-to-net shape products in a short time and low cost. Using these methods, molten metal is poured into a mold cavity which is then solidified into a required casting shape [1]. While manufacturing the products through casting processes, the overall purpose is to fulfill the requirements of both customers and companies such as customers wanting quality products and the company trying to manufacture a defect-free part.…”

Globalization breeds increasing competition. In today's dynamic climate, lean thinking has been found a promising business continuous improvement strategy for improving quality while reducing product cost and delivery time. However, its implementation has dynamic nature of challenges that varies from industry to industry and country to country, necessitating a specific framework by taking all stakeholders onboard. This study aims to propose a lean implementation framework to reduce defects and waste to improve the performance of the metal casting industry. The structure of the framework has been divided into three phases namely the lean conception phase, lean implementation phase, and lean sustainability phase. The proposed framework integrates the six sigma DMAIC methodology with lean tools and techniques to reduce defects and achieve performance improvement. A solid cast software has been used as a computer-assisted casting simulation tool to perform the analysis of defects within the casting. Further, the proposed framework is demonstrated and validated by employing a real-time case study that was manufactured using the sand casting process. The obtained results show remarkable improvements in poured metal weight (33.3%), mold weight including gating system (40%), casting yield (24.56%, rejection rate (90%), and financial saving (24.63%). As a result of analysis of percentage improvements data, the proposed framework can provide the practitioners with a standard roadmap and motivate the casting industries to implement lean for performance improvement through organizational change. Through the effective application of the lean implementation framework, quality enhancement has been demonstrated.

“…There are several methods used in the casting of aluminium alloys. The centrifugal casting process [9], [10]; direct metal casting on a permanent metallic mould [8], [11], [12]; squeeze casting or liquid metal infiltration [13]- [19]; stir casting [20][21]. The metal casting process takes the following steps, as outlined in Figure 1.…”

The RX 100 motorcycle piston was fabricated from end-of-life automobile piston using the traditional sand casting method. The fabricated piston was subjected to thermal analysis using ANSYS R18.1 version software to ascertain its performance under thermal loads. The recycled EOL aluminium used in the fabrication of the piston was characterised using SEM-EDS to determine the composition and morphology of the material. Results obtained show that the EOL aluminium employed in the fabrication of the piston performed excellently under thermal loads, and the SEM-EDS indicates that the material is predominantly aluminium with beneficial alloying elements.
