【行业分析】2025年中国铸件行业政策汇总、发展现状及投资前景预测报告——智研咨询发布

Core Viewpoint - The casting industry is a crucial foundation for the healthy development of various sectors in China, including mining machinery, energy, rail transportation, aerospace, and automotive industries. The country has become the world's largest casting producer, with a projected output of 50.75 million tons in 2024, accounting for approximately 45% of global casting production [2][10]. Industry Definition and Classification - Castings are metal objects obtained through casting methods, involving the pouring of molten metal into prepared molds to achieve specific shapes, sizes, and properties [3][4]. Current Development Status - The casting process has a long history, dating back over 5,000 years, and is the most widely used method for forming liquid metals into solid parts. It involves pouring liquid metal into molds, allowing it to cool and solidify to create castings [6][7]. Industry Chain - The upstream of the casting industry includes raw materials such as pig iron, scrap steel, and non-ferrous metals, along with auxiliary materials and equipment. The midstream consists of casting production enterprises that transform these raw materials into various types of castings. The downstream applications are extensive, covering sectors like automotive, machinery, aerospace, and energy [12]. Production Statistics - In 2024, China's casting production is expected to reach 50.75 million tons, with specific contributions from various materials: - Gray cast iron: 20.6 million tons (40.59%) - Ductile iron: 13.95 million tons (27.49%) - Forged iron: 450,000 tons (0.89%) - Cast steel: 6.28 million tons (12.37%) - Aluminum (magnesium) alloys: 8.32 million tons (16.39%) - Copper alloys: 900,000 tons (1.77%) - Other castings: 250,000 tons (0.49%) [10][2]. Industry Trends - The casting industry is expected to continue evolving with technological advancements and increased quality standards, leading to a higher quality of domestic casting products and a shift towards high-quality development [14].
