加工方法

These components are usually made of iron- or copper-base alloys and very small, so powder metallurgy offers a better method than the processes involving machining, drop forging, die casting, pressing etc.

这些部件一般是铁基或铜基合金，而且尺寸很小，因而用粉末冶金法制造比用切削加工，模锻，模铸，冲压等方法更好。

Unfortunately, I can't really think of a feasable way to cast the dunce cap integrated into the hub without having to do some heavu machining later on, so I am just going to cast it separate and glue it on later.

不幸的是，我真的不能想出一个可行的方法，投下dunce上限，融入中心，而不必做一些heavu加工稍后，所以我刚才去投它单独和胶水，这对后来。
