Die Casting

The advantages of die casting include that the castings have 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 1 cm. Compared with other casting processes, its casting surface is smooth and its fillet radius is about 1-2.5 microns. Compared with sandbox or permanent mold casting, castings with wall thickness of about 0.75 mm can be manufactured. 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, high production speed, casting tensile strength up to 415 MPa, and the ability to cast metal with high fluidity.
