Metal die casting substitution component has significant advantages for both makers and finishers. First, the process is highly efficient. It permits mass production of parts and yet assembly-line quality is maintained across an entire range of output. Assemblers can pick up their favorite part simply from the finished product! This saves time and labor-time translates into lower unit costs for customers. Second, the precision and consistency of die casting make smooth-fitting parts that require little or no subsequent finish work. This extreme accuracy also adds to melted-metal part longevity. Dies last longer and the mold is more well defined in these harder metals. Third, die-cast products are inherently strong. With unmatched durability they are ideal for applications of loading and durability. Lastly, the shape- making flexibility of die casting enables complex geometries and detailed shapes to be made equally well--opening new fields in design wherein innovative products may be coming out soon.
