Investment casting is utilized when complex detail,undercuts or non-machinable features and accurate parts are required.
Investment casting typically requires significant lead time,are best suited for low volume production rates.
Investment casting can meet the tight casting tolerance and good smooth surface.
Investment casting is including four different process:
sodium silicate shell process
complex shell process
soluble glass process
lost wax process
Sodium silicate shell process is the best one which suitable the smaller parts,the tolerance can achieve at CT4~CT5 Grade
