Just one quick question, about how hot do you have to get the metal parts to get the powder to stick when you dust it on?
And how much heat does it take to get the powder to turn into a liquid for dipping?
I really like the idea of dipping a stator into a shallow pan of melted powder so that tops and corners of the arms are immersed and become protected.
You dont have to melt the powder first, just dip a hot stator directly into the dry powder.
As far as temperature, it varies depending on the powder, mainly due to particle size, and what sort of finish you want. Usually we heat to about 200c , which is well below the annealing temp of the stator material, and allows for a nice even flow.
You can heat the parts in your home oven , if the wife permits!!! Or for small parts like R/C stators, a toaster oven would be ideal.
If you look HERE
, you will see the green stator in the housing on one of our machines. This was done with the above "hot dip in dry powder" method.
