Pros / Cons
Advantages:
- Shell-mold casting may be more economical than other casting
processes, depending on various production factors, particularly
energy cost.
- The relatively high cost of metal patterns becomes a smaller
factor as the size of production run increases.
- The high quality of the finished casting can significantly reduce
cleaning, machining, and other finishing costs.
- It has the best product accuracy of all the sand-casting methods.
It can produce small, complicated parts where accuracy is important.
- The sand to metal ratio is low.
- The molds produced are lightweight. They are readily handled
and have good storage characteristics.
Disadvantages:
- The process generates
noxious fumes which must be effectively extracted.
- Equipment and tooling
require a large investment. The raw materials are relatively expensive.
- The size and weight
range of castings is limited.
