It turns out that big and small heads can still do this
The large and small heads that are pressed are basically made in this mode!
This is also the first time I’ve seen it, and it’s an eye-opener.
This may be a more traditional way of manufacturing large and small heads. Generally, carbon steel is suitable, right? If it is heat-resistant steel, is this the same method? ?
There is actually not much information on Haichuan.
They are all made of forged iron and have been tempered.
