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.
