Due to the economic benefits it offers, increasing weight is being attached to investment casting in comparative value analyses. Its scope for optimum shaping is unmatched by any other casting method. Investment castings-oriented design frequently offers an answer to technical problems which would be either impossible or far more expensive to implement using any other method.
The investment casting technique is characterized by
- Almost unlimited scope for the shaping of castings
- Hardly any restrictions in terms of materials
- A high degree of dimensional accuracy due to elimination of the mould parting line usually responsible for casting imprecision
- Facility for complex shaped inner contours due to the use of ceramic cores
- Low material allowance on surfaces to be machined
- A high standard of surface quality
