The secret weapon of investment casting -Applications and considerations for ceramic cores
1. Casting cavity than the outer contour of the surface finish requirements are higher
2. The inner cavity of the casting has a complex structure, or the inner cavity of the casting is larger than the mouth of the inner cavity, so it is not possible to make wax molds with wax mold molds.
3. Small and deep holes inside the casting, or thin and long grooves, which can not be completed by 6-7 layers of shell making.
