Common casting processes and their characteristics
Common casting processes mainly include sand casting, metal casting, die casting, and wax loss casting. Each casting process has its unique characteristics and applicability.
Sand casting is one of the most traditional casting processes, characterized by low cost, wide applicability, and the ability to cast complex shaped parts. The process of sand casting is relatively simple, but the production cycle is long, and the surface roughness of the finished product is relatively high.
Metal mold casting is a high-precision and high-quality casting process suitable for large-scale production of high-precision parts. The characteristics of metal mold casting are high dimensional accuracy and good surface quality, but the cost is relatively high and the production cycle is long.
Die casting is an efficient and high-precision casting process suitable for producing large quantities of small parts. The characteristics of die casting are short production cycles, high production efficiency, but relatively high costs, and strict requirements for molds.
Lost wax casting is a casting process used to produce complex structures, suitable for producing high-precision and high-quality parts. The characteristics of wax loss casting are high dimensional accuracy and good surface quality of the finished product, which can cast thin-walled structures and hollow parts, but the cost is high and the production cycle is long.
Different casting processes have their own characteristics and applicability, and enterprises need to make reasonable choices based on product requirements and production conditions when selecting casting processes.
