Forging is the manufacturing process of pressing, hammering, or rolling metal into the desired shape. This is either delivered from a hammer, press, or die. It is essentially the art of heating and working hot metal to design or shape that is fit for a specific purpose or use. By working the material, it increases many of its properties, including structure, conductivity, and longevity.
CNC machining enables the creation of precision parts and components that would usually be impossible to create manually. The CNC machine removes material from the base stock piece through drilling, milling, turning or other operations to create shapes, angles, and the finished product.
Sheet metal fabrication is the process of turning flat sheets of steel or aluminium into metal structures or products, by cutting, punching, folding and assembling. Sheet metal can be cut, bent or stretched into nearly any shape, which is generally done by cutting and burning the metal.
3D printing is also called an additive manufacturing process whereby layers of material are built up, as the name suggests, to create a 3D part. This is the opposite of subtractive manufacturing processes, where a final design is cut from a larger block of material. Since there is no removal of material, 3D printing creates less wastage. 3D printing is best suited for prototyping or for small batches
