Experiential Scouting Method:New Method of Optimization of Gate Location of Mold Design;

Design Optimization of Plastics Injection Mold Gate Location Based on MoldFlow;

Taking into account the great influences of gate location on part warpage,the computer aided engineering for injection molding was combined with optimization technology to find the optimal gate location with minimized feature warpage.

In view of the importance of gate position and quantity in the design of injection plastic molding,Moldflow,special software for analyzing the plastic flow in mold,was applied to the optimization design of gate in injection mold.

The relations of gate position to product shrinkage,gate dimension to facticity data of tensile strength and toughness of injection materials to mould cavity and ejector mechanism were stated.

The relations between gate position and injection pressure, weldline as well as part thickness in valve-typed controlled filling process are analyzed.

The effect of incision position in phacoemulsification on postoperative astigmatism;

frame connected with openings at different positions are analyzed by using finited element method,influence of openings positions on stress distribution and the way of transferring stress for transfer beam supported on R.
