Numerical simulation technique has become the important verifying tools in extrusion and forging die shape design. It helps designers to know the design parameters space better.
数值仿真技术已成为挤压锻造模具设计中的重要评价手段，有助于设计人员更好的理解设计空间。

In bulk deformation processes such as forging, rolling, extrusion, and wire drawing there is an intentional change in the thickness or the lateral dimension of the workpiece.
大部分的变形过程如：锻造，轧制，挤压和拉丝都有同样的过程就是有意使工件的厚度或外部尺寸发生变化。

Normally, various shape steel materials required to pass through forgingextrusion processing, and just purchased a flat plate were present in the plane of the physical properties.
