Static Casting |
Centrifugal Casting |
|
solidification under the force of earth gravity, therefore blowholes and impurities remain in the material |
solidification under up to 120 times the force of gravity, thereby producing very pure and highly compressed structures |
|
mechanical properties are limited upwards |
substantially better mechanical properties using the same material (comparable with the values of forged parts) |
|
undirected structure, uneven wear |
thanks to directional solidification, structure is directed and wear remains even during application |
|
patterns required (logistics, pattern costs) |
not depending on availability of moulds (moulds from the extensive inventory are used as permanent moulds) |
|
within the framework of technical casting restrictions there is a free choice of moulds |
no restrictions on certain dimensions, however bound to centric bore hole |
|
complicated gating and risering techniques, which have to be taken into account at the time of construction of castings |
no ingates, no feeder heads |
|
limited selection of materials for each pattern |
all materials can be casted (from low alloys to iron-free materials, e.g. Cr-Ni-Mo) |
|
special casting techniques, such as bi-metal casting, hardly possible |
bi-metal casting possible, for example to create a hard outer layer and ductile inner layer inexpensively |
