Sand casting is a commonly applied metal casting process that uses a sand mold as a casting mould into which molten metal is injected and cooled and solidified to form the desired casting. There are four types of moulding materials for sand casting, including clay sand, coated sand, resin sand and water glass sand, each of which can be designed for different parts, and comprehensively, the resin sand moulding material has the highest quality of the final product.
But now the clay wet sand is still the most important moulding material, its wide range of application, the consumption of the amount of large, is any other moulding material can not be compared.
Eathu offers a variety of moulding materials, according to the requirements of different sand casting parts to provide applicable metal materials and metal technology, you are welcome to discuss with our engineers to focus on sand casting.
Sand casting as a common metal casting work has advantages and disadvantages:
In terms of metal materials, sand casting is suitable for all kinds of metal materials, including iron, steel, aluminium, copper and all kinds of alloys, but it is not suitable for high-temperature alloys, and sand casting's heat resistance and abrasion resistance have some limitations for high-temperature alloys.
In the cost, sand casting relative to other casting process, mould manufacturing cost is lower, manufacturing cycle is shorter, very suitable for small and medium batch production. But at the same time sand casting production needs to be desanded after deburring and other additional surface treatment, increasing the production process and cost!
In design, sand casting design flexibility, adjust the mould and core is convenient, can make complex shape, wall thickness uneven castings. But sand casting casting wall thickness has some limitations.
In conclusion, sand casting as a traditional and classic casting process, the use of a wide range, but there are limitations and shortcomings, Eathu can work with customers to choose according to the specific production needs and casting requirements.
Sand casting adaptability, low cost, design freedom and other advantages, so that it has an important application in a number of fields, sand casting in the automotive industry is widely used, mainly used for the production of engine block, crankcase, transmission box, crankshaft, shock absorber seat and other key components, automotive parts are usually on the strength and dimensional accuracy of the requirements of the higher, sand casting can meet these requirements; in the field of steel manufacturing, sand casting In the field of steel manufacturing, sand casting has high strength and good toughness, can be used for the production of large-scale cast steel parts, such as steel bridges, steel structures, billets and so on.
