Casting in China is a core part of the global manufacturing supply chain.

China has thousands of casting manufacturers, factories, foundries, and exporters supplying metal castings to Europe, the USA, the Middle East, and Southeast Asia.

This article explains casting in China in simple English, with a clear material comparison table, price analysis, and detailed FAQs for buyers.

Overview: Casting Industry in China

Casting is a process where molten metal is poured into a mold and cooled to form a solid part. China is one of the world’s largest casting producers due to:

• Large number of professional foundries

• Skilled labor and engineers

• Mature supply chain for materials and machining

• Competitive manufacturing cost

Chinese casting factories produce parts for:

• Automotive industry

• Machinery and equipment

• Valves and pumps

• Construction and infrastructure

• Energy and agriculture

Main Casting Processes Used in China

Chinese foundries mainly focus on three casting processes:

• Investment casting – high precision, smooth surface

• Sand casting – low cost, suitable for large parts

• Die casting – high efficiency for aluminum and zinc parts

Each process fits different product needs and price levels.

Casting Materials Comparison Table (China)

Below is a clear comparison table of common casting materials used by Chinese casting manufacturers and exporters.

Note:

• Prices vary by raw material cost, order quantity, machining level, and quality standard.

• Investment casting costs more than sand casting, but offers better precision.

Casting Price in China: What Buyers Should Know

The price of casting in China is affected by several key factors:

1. Material type – stainless steel costs more than cast iron

2. Casting process – investment casting > sand casting
