This is the gravity casting mold made by our company for Knorr-Bremse Nankou Company from Germany
This gravity casting technology is our new technology made by us that is rare in China
Compared with sand casting:
The appearance, precision and structure compactness have been improved
The formed product does not contain any sand hole and impurity
The cost is only 10-20% of casting cost
Can manufacture products that cannot be machined to form by casting, like engine cover of high speed train
Because the formed products by gravity casting do not contain sand hole and gas hole, they are much more strong than general casting product when hydrostatic test and steam pressure test
