Japanese amazing casting technology. The process of zinc alloy casting without molds.

Thank you for adding subtitles.
It is very helpful and easy to understand.

The process is interesting! But I still don't understand what they are doing, what is it for?

[@Process-ONE]

Casting recycles zinc alloy.
Finished castings are used as molds for various products.

为什么浇筑后加在表面用火焰加热加热？是为了让他从底下向上冷却，避免上下同时冷却中间开裂？

[@Process-ONE]

感谢您的评论。
这是正确的。
如果加热时不硬化，则不会渗透到底部而导致变形和开裂。
这个过程也是提高耐用性所必需的。
