  • Powder MetallurgyProcessing

     · Powder forged parts generally are not as close to final size or shape as cold pressed and sintered parts. This results from the allowances made for thermal expansion effects and the need for draft angles on the forging tools. Further minimal machining is required but when all things are considered this route is often very cost effective.
