structure comes from local suppliers. small rates Dangerous operation Casting Die casting alloys are normally non-ferrous and there is a large number available with a wide range of physical and mechanical properties covering almost every conceivable application a designer might require. Aluminum and zinc alloys are the most widely used. First, the mould is sprayed with lubricant and closed. This lubricant helps control the temperature of the die and assists in the removal of the casting. Molten metal is then injected into the die under high pressure. Die preparation Filing Ejection Shakeout Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces). Reduces or eliminates secondary machining Rapid production rates. Casting tensile strength as high as 415 (60 ksi). Casting of low fluidity metals. The main disadvantage to die casting is the very high capital cost. Both the casting equipment required and the dies and related components are very costly, as compared to most other casting processes. Therefore to make die casting an economic process a large production volume is needed. Turing are simple abstract computational devices intended to help investigate the extent and limitations of what can be computed. In preparing the machine, users will be expected to select the appropriate work holding devices, and to mount and secure Turning produces solids of revolution which can be tightly toleranced because of the specialized nature of the operation. Turning is turning All materials Very good tolerances Short lead Limited to rotational parts Part may require several operations
