: Investement Casting

MAS 2.0 - Guides - F.A.Q. - Tutorials - Home

 

Pros / Cons

Advantages:

  • Suitable for casting high-melting-point alloys with a good surface finish and close tolerances.
  • Little or no finishing is required, which otherwise would add significantly to the total cost of the casting.
  • High degree of design freedom. Complex shapes that would be too costly to machine can be produced quickly and economically as investment castings.

Disadvantages:

  • The labor and materials involved make the lost-wax process costly.
