鋳造剪刀和锻造剪刀的区别

作者: 编辑:
鋳造剪刀:

也就是将金属的粉末,经高温熔化成液态,倒入已经有剪刀型的模具内,等冷却后脱模而出 ,就是剪刀的粗胚,通常在高温金属液注模具时易产生气泡,比较不好的缺点是韧性差.产生气孔的部份保养不易较容易形成锈蚀o



锻造剪刀:
是将有一定厚度的钢板材放入高温炉内经高温而让钢板材的温度升高后.放入冲床上的模具上利用冲床的冲压原理金属板的分子更紧密及完成粗胚成型加工,目地是让剪刀的硬度提高,且韧性也比鋳造的剪刀来的高.

两种刀的优劣不难比较出来.鋳造剪刀的缺点比锻造剪刀来的多.优点来的少.但粗胚完成后,后续的细部加工也与剪刀的耐用度有息息相关的重要性,就如锻造剪刀的后期热处理部分如果处理不善,那也会造成硬度不足,而使得剪刀的刀锋角较容易崩塌营响剪刀的切断能力
