Sand casting is an economical method for producing near net shape components with intricate shapes and complex contours. While it allows for alterations to improve strength, sand casting parts may have irregular surfaces and size variations requiring additional machining. The process has disadvantages including a relatively high defect rate, limitations on dimensional accuracy, safety and environmental controls increasing costs, and potential quality issues from overseas suppliers. However, for many applications the advantages of low tooling costs and design flexibility outweigh the drawbacks of sand casting.

THE PROS AND CONS OF SAND CASTING
Advantages of sand casting
One of the most economical methods of producing near net shape.
The cost of the tools for this process is low compared to alternative methods.
Comparison lowest Teams established and labor costs.
Reduced waiting time for pilot samples and final production quantities .
With internal cutting intricate shapes , reentrant angles and complex contours , which would be very
difficult to machine can be produced through sand casting - mold.
The designer can evaluate the product again by performing stress analysis . The metal can be removed
in areas of low voltage and added in high stress areas with relatively simple alterations to the pattern .
Cast components are usually stable , rigid and strong compared to parts made by other processes.
Sand casting can be machined to improve productivity when a number of the same items will be
produced .
Manufactured by sand casting parts can vary greatly in size and weight , ranging from a few ounces to
several tons.
Virtually any metal that can be melted can be launched .
Material recycling is possible to process , thus reducing wastage
Worldwide, there are literally thousands of potential suppliers of castings made use of this technology
Disadvantages of sand casting
Castings produced by this process may have irregular surfaces , grainy and slight size variations are also
likely.
If the casting surfaces have contact with other parts or moving joints are required , then the casting
would require more machining .

2. Some forms may not be suitable for mass production because of the labor intensive work and the need
for preparation of single mold .
The percentage of casting defects is relatively high due to the gravity flow of molten metal, intricate
shapes possible , irregular thick wall casting design and pattern mold and weaknesses , all of which
results in the second half.
As the dimensions of the cast is limited to about plus and minus twenty mils . Investment casting can
produce much more stringent as pit dimensions but with more than twice the cost of sand casting
Personal safety training and strict enforcement of security processes are essential in view of the laborintensive process in sand handling , chemicals , molten metal, hot metal parts , manual cleaning and
finishing tools , etc. These naturally increase production costs .
Due to the nature of molten metal , and other characteristics of the process, environmental controls and
equipment pollution control are necessary to maintain environmental standards. These significant costs
are added to the process
Potential customers may be tempted by low prices to try buying the developing countries, where quality
systems often can present unpleasant surprises .
All said and done , however , the advantages of sand casting often outweigh its drawbacks. Produces
less waste than a number of other processes of production of metal parts , especially since the material
used not simply be added to the next mold .
