Advantages of Investment Castings:
Greater Design freedom
Feasibility of replacing two or more fabricated sub-assembling by a single piece casting.
Lighter, Stronger components may be designed, without a mismatch, giving an improved aesthetic appearance.
The process permits a high level of consistency, batch to batch.
Compared to other conventional way of manufacturing castings, with lost wax process close dimensional tolerance of ±0.13mm per 25mm and a fine smooth grain finished from 80 to 120 micron inches, 2.0µ to 3.2µ , are normally achieved.
With the ability to produce special alloys to customers' requirements, the choice of metallurgical specifications is virtually unlimited.
The light stressed wax impression dies have a very long life and are not costly considering design complexity.
If required, minor design modification may be made economically without going for few tooling.
Increased productivity can result from reduction or elimination of machining and the consequent deployment of shop floor.
Delivery period for repeat orders in large or small quantities can be 3- 4 weeks.
Comparatively small orders can be produced at economical prices.
A high level of metallurgical integrity and Strength can be achieved in the lost wax process.
