investment casting for stainless steel

Investment casting is a lost wax casting,but it can get a higher tolerance with the silicon  wax,finer sand 

can produce some complex structure parts and think parts,though the casting cost is higher than precision casting,

the process from modeling, develop the casting mold and tooling,wax injection,shell making,baking the shell,lost wax,and pouring,remove the shell,

in order to holding the tolerance,we usually need to adjust the pouring gating and riser,

like the picture, some features that get from the investment casting, we can use them directly, no need machining,

also we can provide the precision cnc machining for some iimportant feature,
