Casting Process

Which casting process is the most widely used?

• Casting

• Forging

• Sand casting

• Mesopotamia casting

What is required for sand casting process?

• Molten metal, sand mold, and pattern

• Furnace, sand mold, and pattern

• Molten metal, sand mold, and furnace

• Pattern, sand mold, and furnace

Why does sand casting have a low productivity rate?

• Because it requires a furnace

• Because it uses sand molds

• Because the mold has to be destroyed

• Because it is a complex process

What is the first stage of the sand casting process?

• Obtaining molten metal

• Creating sand mold

• Preparing the mold

• Pouring the molten metal

What is done after clamping the sand mold?

• Pouring the molten metal

• Cooling down the mold

• Breaking the mold

• Trimming the casting

What is the advantage of sand casting over other casting methods?

• Low tooling cost

• High dimensional accuracy

• Excellent surface finish

• Shorter time taken

What is a limitation of sand casting process?

• High dimensional accuracy

• Excellent surface finish

• Proper maintenance of mold pattern

• Lower dimensional accuracy

What is required for proper solidification of the molten metal?

• Thicker wall thickness

• Lower temperature of the metal

• Quick pouring of the metal

• Longer cooling stage

What is the purpose of trimming and shipping the final product?

• To improve dimensional accuracy

• To improve surface finish

• To remove unwanted layer of metal

• To prevent early solidification
