为了克能压铸工艺的不足之处和更好地发扬其优点而生产出优质铸件,挤压铸造工艺正在不断发展。这种铸造工艺包括原先的将熔化金属浇注凹模型腔,以及在凝固期间通过压头或凸模施加压力。这不是用通常的锻造和铸造能组合成的一种简单操作。因为熔化金属充填型腔和凝固期间将形成铸件缺陷。这是一种慢慢地充填型腔,並在此期间对熔化金属施加压力的好方法。不会滞留空气,监能进行烈处理(T6)。铸件机械性能还得到完善,特别是延伸率、沙比冲击值和抗疲劳性。
In order to overcome the shortcomings of the die-casting process and to better develop its advantages and produce high-quality castings, the extrusion casting process is evolving. This casting process involves the original casting of molten metal into the cavity of the die and the application of pressure by means of a ram or punch during solidification. This is not a simple operation that can be combined with the usual forging and casting. Because molten metal fills the cavity and casts defects during solidification. This is a good way to slowly fill the cavity and exert pressure on the molten metal during this time. Will not stay in the air, supervise the strong treatment (T6). Castings mechanical properties have also been improved, especially elongation, sand than the impact value and fatigue resistance.
