Top 7 China Casting and Foundry Companies 2025
China is the world's largest casting producer, generating over 50 million tons of castings annually representing roughly 45% of global output. The industry covers sand casting (green sand, resin sand), die casting (aluminum, magnesium, zinc), investment casting (lost wax), shell molding, centrifugal casting and continuous casting. Major end-use sectors include automotive (engine blocks, cylinder heads, transmission housings), machinery, energy (wind turbine hubs, pump casings), rail (bogie frames) and construction. Chinese foundries have adopted 3D-printed sand molds, automated pouring lines, spectroscopy-based quality control and simulation-optimized processes. Leading regions include Shandong, Liaoning, Jiangsu, Zhejiang and Hebei.

Frequently Asked Questions
What casting methods are used in China?
China's foundries employ all major casting methods: green sand and resin sand casting (most common, 60%+ of output), aluminum die casting (automotive and consumer electronics), investment casting/lost wax (precision aerospace and medical parts), shell molding, centrifugal casting (pipes), continuous casting, and emerging 3D-printed sand mold casting for complex geometries.
How does Chinese casting quality compare globally?
Top-tier Chinese foundries achieve quality comparable to European and Japanese standards. Weichai, CITIC Heavy and Wanfeng supply global OEMs including BMW, Mercedes, Caterpillar and GE. However, the industry has a long tail of small foundries with variable quality. IATF 16949, ISO 9001 and aerospace AS9100 certifications distinguish premium suppliers.
Does China export castings?
Yes, China is the world's largest casting exporter with annual exports exceeding 5 million tons worth over 30 billion USD. Major export products include automotive castings, pipe fittings, valve bodies, machine tool castings and wind turbine components. Key markets include USA, EU, Japan, South Korea and Southeast Asia.
What materials are cast in Chinese foundries?
Chinese foundries cast the full range of materials: gray iron (GG20-GG40), ductile iron (GGG40-GGG80), carbon steel, alloy steel, stainless steel, aluminum alloys (ADC12, A356, A380), magnesium alloys, copper alloys (brass, bronze) and nickel-based superalloys for aerospace applications.
How is China's foundry industry addressing environmental concerns?
The industry has undergone massive consolidation with small polluting foundries shut down. Leading companies have installed waste gas treatment, dust collection and sand reclamation systems. Electric induction furnaces are replacing cupola furnaces. Many facilities have achieved ISO 14001 certification and meet China's increasingly strict emission standards.
