The advantages and disadvantages of sand casting:

Advantages:
1) Low capital investment means that short production runs are viable;
2) Use of sand cores allows fairly complex shapes to be cast;
3) Large components can be produced;
4) Suitable for small batch production (small production rates)

Disadvantages:
1) The process has a high unit cost, as it is labor intensive and time consuming;
2) The sand mold leaves bad surface finish, due to sand indentation and oxidizing medium, which often requires further processing;
3) Cannot make thin sections;
4) Not suitable for mass production, often used to produce few number of products compared with other casting processes which produce thousands and millions.
