The casting parts
industry has grown by 6.8% CAGR since 2020, driven by automotive and aerospace sectors. China's foundries now produce 49% of global grey iron components, while stainless steel casting exports increased by 22% in 2023. Advanced methods like sand casting and investment casting enable complex geometries with ±0.1mm tolerances.
Four primary materials dominate industrial casting:
Process | Tolerance | Surface Finish (Ra) | Cost per kg ($) |
---|---|---|---|
Sand Casting | ±0.5mm | 12.5μm | 2.10-3.80 |
Investment Casting | ±0.15mm | 3.2μm | 8.50-15.00 |
Die Casting | ±0.05mm | 1.6μm | 4.20-7.50 |
Top-tier Chinese foundries demonstrate distinct advantages:
Customization options include:
Recent successful implementations:
Industry | Component | Material | Production Volume |
---|---|---|---|
Automotive | Turbocharger Housing | SS304 | 500,000 units/year |
Energy | Valve Bodies | Duplex Steel | 2,200 tons annually |
Strategic procurement of casting parts reduces supply chain costs by 18-25% through:
Advanced investment casting parts now achieve 99.2% dimensional accuracy rates, with 30-day lead times for complex geometries.
(casting parts)
A: China widely uses grey iron and stainless steel for sand casting due to their durability and cost-effectiveness. These materials suit automotive and machinery parts. Sand casting also supports customization for complex geometries.
A: Verify certifications like ISO 9001 and review supplier quality control processes. Inspect material reports (e.g., stainless steel, brass) and request samples. Prioritize suppliers with proven expertise in precision investment casting.
A: Die casting uses molds for high-volume, detailed parts (e.g., brass, copper), ensuring smooth finishes. Sand casting is cost-effective for larger, low-volume components like grey iron machinery parts. Machining may follow both processes.
A: Yes, copper and brass parts from sand or investment casting can undergo CNC machining for tight tolerances. This is ideal for plumbing, electrical, and decorative components. Confirm machining capabilities with your supplier upfront.
A: Check compatibility with your machinery type (e.g., die casting, sand casting). Ensure materials (stainless steel, grey iron) meet operational demands. Evaluate suppliers for certifications, lead times, and post-purchase support.
