With the help of Magma software

the high pressure die casting process of automobile engine bracket was simulated.The results show that the bracket’s defects type and location predicted are well agreement with practical ones.The uneven part surface and thickness and gate solidification ahead result in difficulties in exhausting air

together with the poor effect of pressure at the distal end

which are responsible for generation of gas hole.Through analysis of gas hole formation and location

local squeezing device was designed to solve gas holes around the distal bearing hole

and it was observed by X-ray imaging system.Thus

the efficient engine bracket production mode combining with local squeezing process and high pressure die casting as well as CAE analysis was established

which could reduce gas hole rate in the engine bracket to 0.6%

improving effectively production efficiency.
