Understanding the Essentials of Sand Casting Process
The sand casting process remains the most ancient yet persistently relevant method for shaping metal components, accounting for 60% of all metal casting production globally. By compacting specialized sand around a sacrificial pattern, manufacturers create disposable molds capable of withstanding temperatures exceeding 1,600°C. This technique particularly excels in producing large-scale steel sand casting parts, with individual units often weighing between 200kg to 20,000kg.
Technical Superiority in Material Flexibility
Unlike precision casting methods, sand casting accommodates an unparalleled range of ferrous and non-ferrous alloys. Key advantages include:
- 20% lower tooling costs compared to die casting
- Capacity to cast components up to 100 metric tons
- Surface finish options from 12.5μm to 100μm Ra

FAQS on what is sand casting process
Q: What is the sand casting process?
A: Sand casting is a metal-forming process where molten metal is poured into a sand mold cavity. The mold is made from a mixture of sand, clay, and water. Once cooled, the mold is broken to retrieve the solidified metal part.
Q: Which metals are commonly used in sand casting?
A: Common metals include aluminum, iron, steel, bronze, and brass. The choice depends on the application and melting temperature. Sand casting is versatile for both ferrous and non-ferrous metals.
Q: What are the key steps in the sand casting process?
A: Key steps include creating a pattern, forming the sand mold, pouring molten metal, cooling, and removing the casting. The mold is destroyed during part extraction. Post-processing like grinding may follow.
Q: What are the advantages of sand casting?
A: It is cost-effective for large or complex parts and allows rapid prototyping. Sand molds are reusable for new patterns. However, surface finish and precision are lower than other methods.
Q: How does steel sand casting differ from other metals?
A: Steel requires higher melting temperatures, demanding heat-resistant mold materials. It produces strong, durable parts for industrial use. Slower cooling rates may be needed to prevent defects.
