Fabricated Parts may be made using the following processes: a. Adding material, such as 3D printing. b. Removing material, such as cutting, drilling, or machining. c. Bending material, such as sheet metal breaking or thermoforming. d. Casting or molding material, such as injection molding or sand casting. e. Attaching materials to one another, such as welding or chemically bonding (e.g., epoxy).
Fabricated Parts must be made from raw materials. For the purpose of this rule, a “raw material” is any material that would not be considered a “pre-fabricated” part (i.e., has not undergone any of the fabrication techniques listed in <VUR3>
Because casting is a fabrication process listed under VUR3, any material that has undergone casting is not a raw material under VUR4. However, metal billets are cast, and sheet metal and plastic is cast before being rolled. Are billets and sheets of material considered raw material? If so, how does that square with the definition of a raw material given in VUR4?
