An example is Metal Injection Molding where fine metal powders are Injection Molded with a polymer or other binder. Then a series of steps removes the binder and the metal powder is fused into its final shape by heat and pressure ( Sintering ). Other near net shape techniques use precision manufacturing methods such as Isostatic Pressing , Gelcasting , Superplastic Forming , Rapid Prototyping and the Lanxide Process to produce precision parts which require very little finishing work. Reducing traditional finishing such as machining or grinding eliminates more than two-thirds of the production costs in some industries. Near net shape can also be used for structural ceramic production. |
