Sand Casting

What is sand casting? Sand casting is a process that uses sand as a casting material, bonds the sand to form a sand mold, and combines it with a sand core to form a casting mold; then pours, cools, and processes to obtain a casting. Sand casting is one of the most common casting processes because the molding materials used in sand casting are cheaper and easily available; the mold is simple to make and can be used for mass production of most raw materials or single-piece production of castings. We can use sand casting to complete steel, iron, aluminum, and most non-ferrous alloy castings.

The most crucial details in forging that cannot be overlooked

Forging, as one of the essential processes in the field of metal fabrication, aims to transform metal billets into the desired shapes through heating and mechanical deformation. During the forging process, there are numerous details that must not be overlooked, as they directly impact the quality, performance, and reliability of the products. The following will provide a comprehensive introduction to the critical details that cannot be disregarded in the forging process.

What is the casting process of casting steel?

1.Sand Casting: Pattern Creation: A pattern of the desired part is created from wood, plastic, or metal. The pattern is a replica of the final part and includes allowances for shrinkage and machining. Mold Making: The pattern is placed in a sand mold, and the sand is compacted around it. The mold is typically made of two halves, known as cope and drag. Pouring: The mold is opened, and molten steel is poured into the cavity created by the pattern. The steel solidifies within the mold. Cooling and Solidification: After pouring, the steel cools and solidifies. This can take several hours. Shakeout: The mold is broken apart, and the cast steel part is removed. Finishing: The casting may require additional machining and finishing to achieve the desired shape and surface finish.

How to ensure the quality of casting sand

In the process of casting at high temperature, due to the thermal expansion of molding sand, it is very easy to cause minor changes in the size of molding sand, which will affect the dimensional accuracy of castings and the appearance and performance of castings. At the same time, excessive thermal expansion coefficient of molding sand will cause casting defects such as sand inclusion, scab, rat tail, etc. All these factors make foundry enterprises more cautious in selecting molding sand, not only considering the thermal expansion coefficient of molding sand, but also taking into account the cost of molding sand.
