1. 1 Metal Casting Processes Chapter 11 Test yourself!

2. Manufacturing Processes Prof Simin Nasseri Which process is this?! Vacuum molding Uses sand mold held together by vacuum pressure rather than by a chemical binder

3. Manufacturing Processes Prof Simin Nasseri Vacuum molding Which process is this?!

4. Manufacturing Processes Prof Simin Nasseri Lost wax process Or Investment casting Which process is this?! A pattern made of wax is coated with a refractory material to make mold, after which wax is melted away prior to pouring molten metal

5. Manufacturing Processes Prof Simin Nasseri Which process is this?! Die casting (Hot chamber)

6. Manufacturing Processes Prof Simin Nasseri Ceramic mold casting mold is made of refractory ceramic material that can withstand higher temperatures than plaster Which process is this?!

7. Manufacturing Processes Prof Simin Nasseri Which process is this? Casting process in which the mold is a thin shell of sand held together by thermosetting resin binder. Parts made using this process Shell molding

8. Manufacturing Processes Prof Simin Nasseri Which process is this? Uses a mold of sand packed around a polystyrene foam pattern which vaporizes when molten metal is poured into mold EPS (Expanded Polystyrene) process

9. Manufacturing Processes Prof Simin Nasseri Which process is this? Molten metal is poured into rotating mold to produce a tubular part True centrifugal casing

10. Manufacturing Processes Prof Simin Nasseri Which process is this? A permanent mold casting process in which molten metal is injected into mold cavity under high pressure Die casting (Cold-chamber)

11. Manufacturing Processes Prof Simin Nasseri Which process is this? Molten metal is not allowed to completely solidify. After the desired wall thickness is obtained, the not yet solidified molten metal is poured out. Pouring of excess resin from mold. Casting Mold and Final Product. Slush casting

12. Manufacturing Processes Prof Simin Nasseri Which process is this? Instead of using gravity to assist in the metal pour and flow in the mold, a low pressure of up to 0.1 MPa (15 psi) gas is applied to the molten metal. Low pressure casting
