**Brief Introduction of Sand Casting:** Sand casting is one of the oldest and most widely used metal casting techniques in the industry today. It's highly versatile, capable of producing both small and large parts, and can be applied to 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. Green sand casting is commonly used for grey iron and ductile iron. We can produce parts ranging from 0.05 kg up to 15,000 kg, with maximum dimensions of 5000 mm x 2000 mm x 1500 mm. Our molding methods include floor hand molding, jolt squeezer lines, and automatic molding lines, allowing us to meet different weight, size, and quantity requirements. For steel sand castings, we offer both water glass and resin sand options, available in plain carbon, alloy, and stainless steels. The smallest part we can produce is around 1 kg, while the largest can reach up to 20 tons. Parts smaller than 1 kg are typically produced using investment casting (lost wax). Non-ferrous sand castings are also available, using green sand molding. These are ideal for parts weighing between 0.1 kg and 100 kg, with materials such as copper and aluminum alloys. All first article samples come with layout drawings and material certifications via spectrometer. Custom inspection reports are available upon request. Secondary operations like shot blasting, heat treatment, machining, surface finishing, assembly, and custom packaging can be performed on all casting types. Here is a summary of materials and weight ranges for different sand casting methods:
