Due to the special structure and strict technical requirements of the front shock absorber sleeve of motorcycle, which leads to casting defects, such as shrinkage porosity, surface blowhole, are very easy to occur in production.

Discussing various influence factors of ductile iron's surface blowhole defects indicates that bringing various gases in the molten metal or on the interface with the sand mould is inevitable.

对影响球墨铸铁件皮下气孔的各种因素分析表明，铁液中气体的产生有其必然性，通过减少气体的发生量以防止皮下气孔的方法并不是都能奏效。
