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。
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.
由于较高的压力和挤压作用，它比落锤锻造噪声及振动都小得多。
On account of the high pressure and squeezing action, it operates with less noise and vibration than a drop-forge.
粉末锻造零件通常不像冷挤压和烧结零件那样接近最终尺寸或形状。
Powder forged parts generally are not as close to final size or shape as cold pressed and sintered parts.
为了改进经济性与近终形(NNS)成形性，开发了无包套粉末挤压工艺与精压式粉末锻造工艺。
For improved economics and NNS (Near Net Shape) formability, encapsulation-free Powder Extrusion process and coining type Powder Forging process were developed.
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。
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.
一般情况下，各种形状的钢材物料需经过锻造挤压处理，而刚购入的钢板则呈现出平直平面的物理特性。
Normally, various shape steel materials required to pass through forging extrusion processing, and just purchased a flat plate were present in the plane of the physical properties.
