cone-die direct extrusion 锥形模正挤压
direct extrusion molding 直接挤出成型
For direct extrusion presses, temperature tapering of the billet can provide significant increase in press speed without reducing profile quality and in some cases improving profile quality.
对于正向挤压机来说,短锭温度递减却能使挤压速度明显提高,不会影响型材的质量,一些时候还会提高型材质量。
The direct extrusion press design is the most popular design because it is simple to produce, operate and maintain.
正向挤压机是普遍采用的设计,因为它易于生产加工、控制使用和维护保养。
But the direct extrusion press has a thermodynamic problem.
但是正向挤压机也存在一个热力学的问题。
