- High Cost : Investment casting has multiple process steps (wax pattern, ceramic shell, dewaxing, casting, fettling), making it expensive for mass production.
- Longer Manufacturing Cycle : Several days required per batch, leading to longer lead times.
- Moderate Strength : Casting generally results in lower mechanical strength compared to forging, due to internal porosity and grain structure.
- Scalability Issue : Higher rejection rate and limited feasibility for millions of parts annually.
