Die casting processing has excellent dimensional accuracy. Usually this depends on the casting material. The typical value is 0.1 mm for the initial 2.5 cm size, and 0.002 mm for each additional cm.
Compared with other casting processes, its casting surface is smooth, and the fillet radius is about 1-2.5 microns.
Compared to sandbox or permanent mold casting methods, castings with a wall thickness of about 0.75 mm can be produced. It can directly cast internal structures, such as wire sleeves, heating elements, and high-strength bearing surfaces.
Other advantages include its ability to reduce or avoid secondary machining, fast production speed, casting tensile strength of up to 415 MPa, and the ability to cast high-fluidity metals.
A precision casting method. The dimensional tolerances of the die castings cast by die casting are very small, and the surface accuracy is very high. In most cases, the die castings can be assembled and applied without turning. Can be cast directly.
From small parts such as general camera parts, typewriter parts, electronic computing devices and decorations, as well as parts of vehicles, locomotives, airplanes and other vehicles, most of them are manufactured by die casting.
