Water-cooled motorcycle engine cylinder head adopts low-pressure casting blank.During initial production period,it appears more serious casting defects. Through the re-design of the cooling system,exhaust system and gating system,the qualiifed rate of the cast is improved from the original 30%~40% to 90%,also the surface quality of the important part of the casting and the comprehensive quality assessment have been signiifcantly improved,to meet the technological requirements.
