How Accurate Is Sand Casting?
When many people learn about casting technology, they often ask: "Is sand casting precision high?" This question is very practical. The answer is that although sand casting's precision is not as high as that of precision casting and die casting, it is accurate enough in most industrial scenarios, and under proper control, the dimensional error can be completely controlled within ±1mm, and the surface roughness of sand casting can also meet the technical requirements of most parts. Therefore, if you are not making blades for aircraft engines or high-precision molds with extreme requirements, sand casting is actually a very cost-effective choice.
Sand casting is a practical and flexible process that is suitable for the production of various small and medium-sized batches of parts, especially when manufacturing large-sized and complex parts. As long as the mold design is reasonable and the processing is properly controlled, the experienced casting team can achieve high precision, stable quality, and more controllable costs. This is why many large-scale mechanical equipment, engineering accessories, wind power equipment, and automotive parts choose sand casting.
FUDING started with sand casting and has rich experience. Whether it is gray cast iron, ductile iron, carbon steel, or stainless steel, we can produce it, no matter how complex the structure is. Our professional technical team will design reasonable molds and pouring systems according to the customer's drawings to ensure that the castings are full, dense and pore-free. Throughout the production process, we use different process types such as resin sand and coated sand, which can be flexibly matched according to the performance and requirements of the product, which not only ensures the dimensional accuracy of the castings, but also improves the surface quality.
We have a complete casting production line, including core facilities such as automatic sand processing systems, and have an annual production capacity of thousands of tons of castings. Whether it is a small accessory weighing tens of kilograms or a large shell, base, or wheel hub weighing several tons, we can undertake production. And our castings can be directly sent to the subsequent machining workshop and shipped after finishing, which greatly saves customers' time and cost.
Our current customers are in many fields such as machinery manufacturing, rail transportation, energy equipment, mining equipment, etc. Many of them have cooperated with us for many years, place orders regularly every year, and have regarded us as their long-term supply partner.
