**Brief Introduction of Sand Casting:**
Sand casting is one of the oldest and most widely used metal forming processes in the industry today. It is highly versatile, capable of producing both small and large components from a wide range of materials. Our company offers various types of sand casting, including green sand, resin sand, and water glass sand castings, suitable for both ferrous and non-ferrous materials.
The most common green sand castings are made from gray iron or ductile iron, with weights ranging from approximately 0.05 kg to 15,000 kg. The largest parts can be as big as 5000 mm x 2000 mm x 1500 mm. We use different molding methods such as floor hand molding, jolt squeezer lines, and automatic molding lines to meet the specific needs of our customers in terms of weight, size, and quantity.
For steel sand castings, we provide both water glass and resin sand options, available in plain carbon, alloy, and stainless steels. The smallest steel casting we produce is around 1 kg, while the largest can reach up to 20 tons. For parts smaller than 1 kg, we recommend investment casting (lost wax) instead.
Non-ferrous sand castings are also available, using green sand as the primary molding method. These castings typically weigh between 0.1 kg and 100 kg and include aluminum and copper base alloys.
All first article samples come with detailed layouts and spectrometer certifications. Custom inspection reports can be provided upon request. A variety of secondary operations, such as shot blasting, heat treatment, machining, surface finishing, assembly services, and custom packaging, can be applied to all types of sand castings.
