Casting is one of the oldest metal forming methods. Approximately 15% to 20% of auto parts are castings produced by different casting methods. These castings are mainly key components of the power system and important structural components. These countries generally use digital technology to improve the level of casting process design. The casting rejection rate is about 2% to 5%, and a transnational service system has been established and network technical support has been implemented.
The application of casting in four-wheel automobile parts manufacturing has reached a high level of maturity. Four-wheel automobiles come in a variety of types based on specific needs and preferences. Within each category, there can be further subtypes and variations. This underscores the importance of automotive casting. Automotive casting includes auto part casting, wheel castings, differential housing castings, and so on.
Recent Trends and Developments in Automotive Casting Materials.
1. Aluminum Alloy Casting Technology
New casting technologies are continuously evolving to improve component quality and production efficiency. For instance, Norway's HyForge project demonstrates a new process for manufacturing aluminum suspension components that enhances part performance and reduces the carbon footprint.
2. Market Dynamics and Investment
Companies are enhancing their market competitiveness through business expansions, joint ventures, and acquisitions in the automotive casting sector. For example, Wencan has announced the construction of a new aluminum die-casting component production base in Anhui Province, China, focusing on parts for new energy vehicles.
3. Environmental and Cost Efficiency
Emerging casting technologies not only offer performance improvements but also present significant advantages in terms of environmental impact and cost efficiency. By optimizing production processes, reducing material waste, and minimizing energy consumption, casting technologies contribute to lowering production costs and environmental impact of automotive components. For example, Raufoss Technology has successfully reduced carbon emissions in the production process by introducing cast bolts instead of extruded bolts.
These trends reflect a focus on improving performance, reducing environmental impact, and meeting the evolving needs of the automotive industry.
