1. Careful revision on the drawings, supporting by 3-D mould's software of PRO/E, solidwords and Auto CAD, building the 3-D moulds to imitate the real parts according to the customers' drawing
2. Full dimensions inspection and note in the drawings for the first artile submittion
3. Further CNC machining centers' machining work, CMM inspection when production
4. Mold preparation - The walls of a cylindrical mold are first coated with a refractory ceramic coating, which involves a few steps (application, rotation, drying, and baking). Once prepared and secured, the mold is rotated about its axis at high speeds (300-3000 RPM), typically around 1000 RPM.
5. Pouring - Molten metal is poured directly into the rotating mold, without the use of runners or a gating system. The centrifugal force drives the material towards the mold walls as the mold fills.
6. Cooling - With all of the molten metal in the mold, the mold remains spinning as the metal cools. Cooling begins quickly at the mold walls and proceeds inwards.
7. Casting removal - After the casting has cooled and solidified, the rotation is stopped and the casting can be removed.
8. Finishing - While the centrifugal force drives the dense metal to the mold walls, any less dense impurities or bubbles flow to the inner surface of the casting. As a result, secondary processes such as machining, grinding, or sand-blasting, are required to clean and smooth the inner diameter of the part.
