👉 Pour engineering, also known as pour casting or investment casting, is a sophisticated metal casting process used to produce high-precision, complex parts with intricate geometries. The process begins with creating a wax pattern or mold, which is then coated with a refractory material and encased in a ceramic shell called a "clay core." Molten metal, typically an alloy, is then poured into the clay mold under high pressure, ensuring a tight fit and eliminating air pockets. After cooling, the ceramic shell is carefully removed, leaving behind a hollow, precise metal part. This method allows for superior surface finish, tight tolerances, and the ability to create parts with internal features that would be difficult or impossible to achieve through other casting techniques. It is widely used in industries such as aerospace, automotive, and medical devices due to its efficiency and precision.
