What is the difference between precision casting and casting
The main difference between precision casting and casting is that the manufacturing method of casting is simpler, while precision casting has higher accuracy and better surface quality.
Casting is a method of making parts by pouring molten metal, glass, ceramics, and other materials into a mold, and then cooling and solidifying them. It has the advantages of low cost and high production efficiency, and is suitable for producing a large number of workpieces. However, due to the large deformation of the mold during the casting process and the high difficulty of processing, the accuracy and surface quality of the parts are relatively poor.
In contrast, precision casting is a more refined manufacturing method that produces parts with higher accuracy and better surface quality. Precision casting usually uses high-precision and high-quality molds to control parameters such as temperature and pressure during casting to ensure the accuracy and quality of the product. Due to the relatively complex manufacturing process of precision casting, the cost is also relatively high, making it suitable for producing workpieces with high requirements for precision and surface quality.
In addition to precision and surface quality, precision casting also has better mechanical properties and corrosion resistance. Because in the process of precision casting, the flow state of metal liquid is relatively slow, which can better eliminate gases and impurities. At the same time, precision casting can also control the microstructure and grain size of the metal, thereby improving the strength and durability of the parts.
Overall, precision casting and casting are two different manufacturing methods that are suitable for different production needs. Casting is suitable for producing large quantities of workpieces with low requirements, while precision casting is suitable for producing workpieces with high requirements for precision, surface quality, mechanical properties, and corrosion resistance.
