When considering which manufacturing process to use, it is important to know that investment casting requires less machining than other production methods. The key reason for this is investment casting’s near-net-shape process. The molds that form the molten alloys into cast parts are extremely accurate, resulting in castings that are very close to the manufacturing specifications, often within tolerances. They also produce high-quality finishes. Because of these and other factors, investment castings often require little or no machining and finishing work. That saves time and cost, while improving quality and consistency.
