DIESUB是什么工艺

die-casting和forging的工艺流程和区别在于:

die casting,压铸,是一种金属铸造工艺,其特点是利用模具腔对融化的金属施加高压。模具通常是用强度更高的合金加工而成的,这个过程有些类似注塑成型。大多数压铸铸件都是不含铁的,例如锌、铜、铝、镁、铅、锡以及铅锡合金以及它们的合金。根据压铸类型的不同,需要使用冷室压铸机或者热室压铸机。

forging,锻造,是一种利用锻压机械对金属坯料施加压力,使其产生塑性变形以获得具有一定机械性能、一定形状和尺寸锻件的加工方法,锻压(锻造与冲压)的两大组成部分之一。通过锻造能消除金属在冶炼过程中产生的铸态疏松等缺陷,优化微观组织结构,同时由于保存了完整的金属流线,锻件的机械性能一般优于同样材料的铸件。相关机械中负载高、工作条件严峻的重要零件,除形状较简单的可用轧制的板材、型材或焊接件外,多采用锻件。

挤压铸造(squeeze casting)和压铸(die-casting)有什么区别呢?
提示:

挤压铸造(squeeze casting)和压铸(die-casting)有什么区别呢?

挤压铸造是指对型腔内的金属液(或半固态浆料)施加很高的压力进行挤压,使得破坏晶枝的生长,在压力下补缩,从而得到品质很好的铸件的压铸成型方法。
压铸就是高压铸造。区别:1.挤压铸造的产品没有气孔,基本没有缩孔疏松。2.挤压铸造的铸件内部比较致密,可以达到气密性要求3.可以做T6等固溶处理进行强化,抗拉强度,伸长率都有提高4。可以焊接.5,表面耐腐蚀性能优于压铸件。
