Reverse Engineering: The "New Old Secret" | Pumps & Systems
Pattern makers take the reverse engineered design and create a pattern of the object using wood, metal or plastics. The completed pattern is then used to produce molds for casting the component. Alternatively, a CNC sand milling machine can be chosen because it uses precision tooling to cut out sand molds for various pump components.
