The production process of stainless steel precision castings is more complex, and the requirements for dimensional accuracy are high. There are three main shell-making processes for stainless steel precision castings, namely water glass process, silica sol process and silica sol composite process. Let's introduce them one by one.

The basic feature of silica sol precision casting is that it uses fusible material as the pattern and refractory as the casting mold. Before pouring, the pattern is melted to form the cavity of the casting mold. As early as 3000 years ago, this process has been used to cast handicrafts. During the Second World War, due to the needs of the military industry, the United States, Britain and other countries used investment casting to produce the stationary blades of turbojet engines, which pushed the process to the industrial field and has been continuously developed and improved for more than half a century. The production process of silica sol investment casting is various, from wax pattern, shell, pouring to cleaning, which is a tight chain. Any problem in any link will directly affect the forming and quality of the final casting, so it is necessary to strengthen the control and research of the process.

Shell molding casting, also known as shell mold casting, is a metal casting process that uses a mold made of a thin shell of sand resin mixture that is heated and cured to create a rigid mold

Iron sand casting is a widely used manufacturing process in which molten iron is poured into a mold made of sand to create various metal components. However, like any other manufacturing process, iron sand casting is not without its flaws. In this article, we will explore some common defects that can occur during the iron sand casting process and discuss ways to prevent or minimize them.

What are the reasons for the shrinkage of ductile iron castings? Some foundry manufacturers or customers will want to know what are the reasons for the shrinkage of ductile iron, and the following Quansheng machinery manufacturers will take you to understand what are its influencing factors.

Shell molding iron casting is a popular manufacturing process used to create complex metal parts. This process involves the use of a mold made from a mixture of sand and resin, which is then heated to create a hard shell. Molten iron is then poured into the shell, creating a precise and detailed casting.
