Compared with ordinary mode forging, the main advantages of precision die forging are: less than mechanical processing, even zero; raw material savings; high labor productivity: low production cost; high dimensional precision mold forging, dimensional tolerance The size tolerance of ordinary die forgings is small, generally only half of ordinary die forgings, or even smaller; the surface quality is good, the surface roughness of precision mold forging is low, and it can reach Ra 0.8 ~ 3.2 μm.
Compared to cutting, the main advantages of precision die forging are: because the shape and size of the forged blank are close to the finished parts or even completely consistent, the material utilization is high; the distribution of the metal fibers is consistent due to precision plastic forming, the distribution of metal fibers is consistent with the shape of the part, so The mechanical properties of the parts have great improvements, so precision die forging, also known as less cutting processes.
Compared with ordinary die forging, it features a desirable forging forging, the shape of the forging forging is complex than the general mold forging, and the general mold forging can simplify the shape by increasing the remaining blocks, while the forging forging is close to the shape of the part; the wall thickness of the forging forging The size of the rib is smaller than the general mold forging, because the general mold forging has a processing margin, and the forging forging is generally non-processing margin or less processing margin: the die forging is small, and even cannot be used for forging, slope: The dimensional accuracy and surface quality of the precision forging are high than the general die forging. The metal stream wire can surround the contour of the part, so the mechanical properties and stress resistance are high; the dimensional precision and surface quality requirements of precision forging are high, often After the initial refinement, it is necessary to add a finishing process.
