Sand casting is generally cheaper than investment casting and die casting.
The price of sand casting varies widely, influenced by factors such as product type, processing complexity, and material.
Price Range
Simple castings: Approximately ¥8.0-¥25.0 per piece (such as small aluminum parts and hardware).
Complex castings: ¥30.0-¥300.0 per piece (such as mechanical housings, valves and fittings, and precision parts).
Mass production: The unit price can be reduced to ¥1.5-¥3.0 per piece (subject to reaching a certain production volume).
Price Influencing Factors
Material Selection: The cost of materials such as aluminum alloy and cast iron varies significantly, directly affecting the total price.
Processing Difficulty: Castings with complex structures or requiring CNC machining are more expensive. For example, precision die castings can cost over ¥50.0 per piece.
Minimum Order Quantity: Small batches have higher unit prices (e.g., ¥159.0 per piece). Larger batches can reduce average costs (e.g., ¥8.50 per kilogram). We recommend inquiring based on your specific needs, as quotes from different manufacturers can vary by 30%-50%.
Sand casting, as the most basic and widely used casting process, holds a key position in multiple industrial sectors due to its low cost and adaptability. The following is a detailed analysis of its specific application areas:
Major Application Industries
1. Automotive Manufacturing
Sand casting is primarily used in the automotive industry to produce core engine components, such as cylinder blocks, cylinder heads, crankshafts, and other cast iron parts. These components must withstand high temperatures and high pressures, and sand casting ensures a dense internal structure. Complex structural parts such as transmission cases and differential housings are also commonly produced using this process.
2. Construction Machinery
Critical components such as hydraulic valves, pumps, and pipe fittings in various types of construction machinery are often sand cast. Sand casting offers advantages in producing castings with complex internal cavities and accommodating small-batch customization requirements, such as track shoes for excavators and counterweights for loaders.
3. Aerospace Industry
Although aerospace components are mostly produced using precision casting, some large structural parts and brackets are still produced using sand casting, particularly for aluminum alloy aircraft auxiliary components. The application of 3D printing sand casting technology has further expanded its potential in the manufacture of complex aerospace parts.
4. Railway and Shipbuilding
Heavy castings such as train wheels, ship propellers, and large marine diesel engine cylinder blocks are often produced using sand casting. Each piece can weigh several tons, making it difficult to replace other casting processes.
Sand casting is particularly suitable for applications that require a balance between cost and complexity. Its advantages are particularly evident when the product is large or the material has poor plasticity.
