Process Introduction
Sand casting, a traditional casting process, adopts high-quality raw sand as the main molding material to produce molds (equivalent to “dies”) for casting production.
Characteristics of Sand Casting
It is a casting method that uses molding sand to form molds for molten metal pouring, generally referring to the sand-casting process under gravity.
Process Flow of Sand Casting
Common Materials for Sand Casting
Gray Iron, Ductile Iron, Cast Steel, Aluminum Alloy, Copper Alloy, etc. Material grades can be specified by customers.
Application Fields
Machinery, construction machinery, valves, pipelines, auto parts, general machinery and other industries.
Process Advantages of Sand Casting
- Low tooling cost
- Excellent flexibility for large, special-shaped and thick-walled parts
- Wide material adaptability without major process adjustment
- High design freedom for complex structures
When to Choose Sand Casting
Sand casting is your best choice when:
- You are looking for a budget-friendly manufacturing solution
- You need large, irregular or thick-section custom castings
- Ultra-high precision and mirror surface finish are not required
- You need to use various metal materials without changing production processes
* Sand casting is more suitable for medium and large industrial castings with complex structures that do not require high-precision surface finish.
* For ultra-high precision, mirror surface and tiny precision parts, other precision casting processes are recommended.
