Abstract

This review explores seven die casting methods: High-Pressure Die Casting (HPDC), Low-Pressure Die Casting (LPDC), Vacuum Die Casting (VDC), Gravity Die Casting (GDC), Squeeze Casting, Semisolid Metal Casting (Thixomolding), and Cold Chamber Die Casting. Each method is evaluated based on its advantages, limitations, and industrial applications. HPDC is widely used for high-volume production but faces challenges like porosity and mold wear. LPDC offers better material density with slower production rates. VDC produces high-quality components with minimal defects but is more costly. GDC is suitable for simple geometries and smaller volumes, while Squeeze Casting delivers high strength and density, ideal for automotive parts. Thixomolding offers precise material flow, producing lightweight, strong components. Cold Chamber Die Casting is effective for high-melting metals but requires careful heat control. The review also discusses advancements in materials, mold designs, and simulation technologies, which enhance the efficiency and sustainability of die casting processes. Despite existing challenges, die casting remains a critical method for high-precision, large-scale manufacturing. Choosing the right method depends on product specifications and industry needs.

Abstract

Boilers are one of the important components in the industrial sector, with their thermal efficiency largely dependent on the ability to utilize the heat energy produced. Economizer is the main device used to improve boiler efficiency by utilizing residual heat from flue gases to heat feed water, thereby reducing fuel consumption and greenhouse gas emissions. This research aims to review the literature related to optimizing the economizer manufacturing process, including material selection, design, and production technology, in order to improve boiler thermal efficiency. The review shows that materials such as stainless steel and copper have a great contribution in improving thermal conductivity and corrosion resistance. In addition, new material innovations, such as ceramic and polymer composites, offer significant potential for improving economizer performance. On the other hand, manufacturing processes such as high-precision welding and strict quality control prove instrumental in ensuring the structural integrity of the economizer. By optimizing manufacturing processes, boiler efficiency can increase by up to 15%, while supporting sustainability by reducing greenhouse gas emissions. This research confirms that further development in economizer design, materials and manufacturing technologies is necessary to meet the needs of a sustainable industry. Thus, economizer is not only a solution for energy efficiency but also a strategic step in supporting a more environmentally friendly energy system.

Abstract

The field of energy storage is undergoing significant transformation through the integration of additive manufacturing (AM). However, current challenges persist in addressing the optimization of material properties, precision, and manufacturing constraints in thermal energy storage (TES) systems. The aim of this study is to review the advancements in AM techniques as applied to TES systems, focusing on their ability to enhance thermal efficiency, reduce material wastage, and improve economic viability. The methodology employed is a systematic literature review (SLR), consolidating findings from previous studies to identify the effectiveness of AM in fabricating TES components. Key findings highlight that AM enables the creation of complex structures, such as lattices and composite phase change materials (PCMs), that improve heat transfer, thermal conductivity, and system stability. For instance, optimized fin designs produced via AM have reduced conduction resistance by up to 17 times. Additionally, integrating lattice frameworks and porous matrices has enhanced energy storage capabilities by improving temperature uniformity and reducing phase change material melting times. AM demonstrates transformative potential in TES by enabling innovative designs and efficient material usage. However, further research is required to address scalability, cost-effectiveness, and high-resolution manufacturing to fully realize its application in industrial energy storage systems.

Abstract

CNC milling technology is essential to today's industrial sector because it makes it possible to produce components precisely and efficiently. In this study, CNC milling machining parameters are optimized using the Taguchi technique and Response Surface Methodology (RSM). We also analyze several other characteristics such as Spindle Speed (SS), Feed Rate (FR), and Depth of Cut (DoC). To determine important factors and ideal configurations, this study blends statistical analysis, such as ANOVA, with experimental methods. According to the study's findings, the two most important variables affecting surface roughness (Ra) and Material Removal Rate (MRR) are FR and DoC. The optimization approach can help improve product quality while cutting down on production time. This in turn promotes the manufacturing process's efficiency.

Abstract

This research examines various approaches in improving the quality and efficiency of the aluminium recycling process, focusing on the effect of waste type, casting method, and process parameters on the mechanical properties of the resulting product. Several studies have shown that the type of aluminium waste, such as pistons and cans, affects the hardness of the final product, while non-conventional cooling media such as coconut milk water can produce a more homogeneous microstructure. In addition, casting methods such as centrifugal casting are superior to sand casting in producing tighter microstructure and better mechanical quality. The addition of elemental tin (Sn) to recycled aluminium has also been shown to improve hardness and wear resistance, making it more suitable for severe applications. Controlling the casting temperature and controlling porosity are also important factors in obtaining products with optimum mechanical strength. While these results are promising, further research is needed to optimise cost efficiency, environmental impact and sustainability in the aluminium recycling process.

Abstract

Tensile strength in Shielded Metal Arc Welding (SMAW) is a critical parameter that significantly impacts the material's performance in mechanical structures. This welding method is widely used in various industrial applications, especially for carbon steel materials, due to its practicality and relatively low operational costs. This study aims to analyze the factors affecting tensile strength in SMAW welding, including welding current, electrode type and size, welding position, cooling medium, and welder skill. The analysis results show that increasing welding current can improve penetration and tensile strength, although it carries the risk of defects such as porosity and reduced weld quality. Selecting the right electrode, such as E7016, provides better tensile strength results compared to E7018, which excels in crack resistance. The horizontal welding position produces more consistent weld quality, while overhead position increases the risk of defects. Additionally, the cooling medium plays a significant role, with slow cooling using air or sand leading to a microstructure that supports better tensile strength compared to rapid cooling with water. Welder skill is also an important factor in controlling welding parameters to achieve optimal and strong welding results.
