Investment casting process offers many benefits including cost savings, design freedom, close tolerances, better finishes, savings in machining time and assembly savings.- _( |2 l, w; E4 U$ w0 r
1. Low Initial Tooling Costs: Initial tooling costs averaged over the parts produced are often less than other manufacturing tool costs.
