hot-extrusion die

While manufacturing a hot-extrusion die made of RM-2 hot working die steel, quenching cracks was found during the quenching process.

在制造热挤压模具的过程中，所用的模具钢rm - 2在淬火过程中发生了淬火开裂。

Form and dimension may also be achieved by a number of alternative processes such as hot or cold extrusion, sand casting, die casting, and precision casting.

形式和尺寸也可以通过其它一些可选工艺来达到，比如热挤出或冷挤出加工，沙模铸造，拉模铸造，或精密铸造。

So, in hot extrusion process, how to reduce wear and improve die life is one of the most concerned problems for mold designer.

因此，在热挤压过程中，如何减少磨损、避免局部磨损过大是设计人员最关心的问题之一。
