To produce complex titanium parts more cost-effectively, machine shops are increasingly incorporating advanced forging equipment to complement their existing CNC capabilities to create near-net-shaped parts that only require minimal machining. In some cases, the forging process is so precise that no additional machining is required. There are significant advantages to include forging in a machine […]

To truly understand certain aspects of sand compactability, it is important to know the simple science behind it. Let\’s get started without further ado! Do you periodically send green sand to an outside lab for testing to compare testing results? If you do, you must have noticed that their moisture content is similar to your […]

Iron oxide threatens all iron-melting processes. In cupola melting, much greater amounts of iron oxide are produced during the normal melt cycle than are produced in electric furnace melting. This makes iron oxide’s effect much more pronounced in cupola melting. In EF melting, 20%-30% oxidation loss is the extreme of losses encountered. In cupola melting, […]

Thousands of years ago duplicate metal structures were cast from an original sculpture by the lost-wax casting process. Investment casting is one of the oldest metal-forming techniques based on this lost-wax casting process. A beeswax pattern is coated with refractory ceramic material, which then hardens and takes the shape of the casting. The ceramic mold […]
