Latest Patents
Hempel holds a patent for a process titled "Production of high density powdered metal parts." This patent describes a method of forming powdered metal into finished or near-finished, high-strength structural parts of complex configurations. The process involves heating a metal powder preform to approximately 2100°F and forming it at relatively low pressures ranging from 19 to 39 tons per square inch. This technique produces a metal part with a density of over 99% of theoretical density. The preform is created from a prealloyed metal powder blended with graphite and a lubricant, compacted to a density of 70 to 80% of theoretical density, and heat-treated for oxide reduction and solutioning of the graphite. Rapid transfer from heat treatment to the preheated forming die is crucial to minimize reoxidation and cooling.
