1,不锈钢模具过模间隙要比碳钢的要大。随着产品的长度增长而增大。


2,不是所有不锈钢螺丝的线材都需要草酸的,一般直孔模或者缩的很短的,缩比不大的直接白线就好了。草酸后表面轻拉适合,增大表面硬度,适合强束和缩杆。


3,做不锈钢机器一定要好点的。同样的机器打铁的好做再做不不锈钢的话不一定能做。


4,润滑油有要求的,不是普通机油就可以的。不在乎机器外观和寿命直接用厚白漆加机油调和下就OK。


5,不锈钢线材加热要适而可止,不是温度越高越好。温度越高对模具的寿命影响很大。有的普通头型的不用加热也很好做。

6,不锈钢模具,主模钨钢要选合适的型号。否则容易裂或者不耐磨。顶针最起码要H55以上的材质。
能想到的就这么多了。

7,热处理,一般的不锈钢螺丝是不需要热处理的,搓牙后直接清洗抛光烘干就可以包装了。特殊材质的是需要热处理的,退磁,加硬。
