Precision machining combined with precision casting can be indeed considered as precision manufacturing. Though steel investment casting process is called as precision casting which indeed can obtained neat shape casting, however, that doesn’t mean it doesn’t need any secondary machining. Furthermore, the lost wax casting process applied in common industrial field has still stayed at low but economical level which is so far from so called neat shape casting.
