This paper researched the application of non-mold casting technology for reducing the development cycle and cost of tractor diesel engine cylinder body.The detail of the each process method has explained which based on the non-mold casting process of a diesel engine cylinder block.The results showed that rapid casting of diesel engine cylinder block can be realized by the non-mold casting composite forming technology,combined with CAD/CAE technology and virtual reality technology.The advantages of this method have fast speed,low cost,green,and lightweight,that is to say,piece manufacturing cycle was shortened by more than 50%,single piece manufacturing cost was reduced by more than 81%,and 8-9 molds were saved.
