This paper introduces the character of ObjectARX and the process of developing CAD system of cast process with ObjectARX,and the technical piths invloved.

Application of CAE to Design of Casting Process for Piston;

Improving on casting process with computer simulatoin of ZG1Cr18Ni9 valve body;

The Production and Casting Process of Nodular Iron Casting Body;

Design and Realization of a Casting Technology CAD System by Further Development on Pro/E;

Casting technology of cylinder sleeves for large marine diesel engines;

Casting Technology for Screwy Sheath of Double Screw Roller Grinded-paste Machine;

The Optimal Casting Technique Design of Water Turbine Runners;

Therefore computer aided design for structure and casting technique of supporting trunnion roller is realized.

Through the improvement on casting process, the horizontal tilting metal mould casting technique has been adopted to produce Al alloy pressure-tight shells.

An introduction was made to the foundry method of CY4D series diesel engine cylinder block and head,as well as the quality problems met during the trial production and their prevention measures including: leakage of cylinder head; dimensional deviation of block after machining and cylinder cores cracking.

The foundry method design of a nodular iron reductor housing with ferrite matrix was de-scribed.

The foundry method scheme, gating system design, melting and treatment of the molten iron was described.
