The more details there are that need to be considered with a
particular work piece, the more can the real advantages of the
investment casting process be utilized.
Undercuts, complex geometries, small wall thicknesses and exact
letterings can all be realised without difficulties if applying
the investment casting process. No expensive mechanical extra
treatment is needed.
The freedom to create almost arbitrary shapes, forms and designs
is one of the essential advantages of the investment casting
process. Narrow tolerances too are an important feature.
Customers are free to select from a large variety of different
materials, some of which are even apt for investment casting
only.
No surface can be more precise than one created by way of
investment casting. Another advantage lies with the high
repeating accuracy, a feature of great importance in regard to
the production of series parts.
Rapid prototyping enables, in a fast and cost-effective manner,
to produce investment casting specimen that come as close to the
final series product as possible. For the manufacture of these
prototypes, we can cast all types of steels that suit for
investment casting.
