What Is Smelting And Sintering cipref-bourgogne.fr
sintering a melting or smelting process. Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.
Sintering vs Melting: What's the Difference?
Sintering has a few different uses. One of the key uses of sintering is to join metal particles together—sintering is often used on metals with high melting points, since it doesn’t rely on reaching melting temperatures to work. Some 3D printing devices operate by sintering metals one layer at a time to create custom metal forms. Sintering
