Investment casting is a manufacturing process in which molten metal or alloy is poured into a mold at high temperatures so that it solidifies into a part or product of the desired shape. Precision casting is usually used to manufacture parts with complex shapes, high precision and high quality requirements, such as parts in aerospace, automobiles, medical equipment and other fields.
Precision casting is characterized by its ability to produce parts with high dimensional accuracy, good surface finish, and high material utilization. Its manufacturing process requires precision molds and precisely controlled casting process parameters, such as temperature, pressure and cooling rate. Common investment casting methods include investment casting, pressure casting, low pressure casting and lost wax casting.
Precision casting has important application value in industrial production and can meet the manufacturing needs of various complex parts. At the same time, precision casting can also reduce material waste, improve production efficiency, and reduce costs, so it has received widespread attention and application.
