Engine cylinder

as one of the key parts for the engine

is a typical difficult-forming complicated part

which exhibits the feature not only larger size

complex structure

thin wall with un-even thickness but also narrow processing method and many influencing factors

so it is suitable for production by LFC（lost foam casting）.Mould design is a key procedure in producing engine cylinder.The desirable design can not only reduce the requirements for production conditions

but also improve the qualified rate and comprehensive performance of the parts.The mould for LFC engine cylinder with excellent structure was designed by considering the features of the parts and convenience of next-manufacturing combining with the characteristics of LFC mould

which is beneficial for improving the qualified rate and comprehensive performance of the cylinder.
