Not surprisingly, I got several replies pointing out the propensity of plastic
to melt at the temperatures required for powder coating.
I should have mentioned that I wasn't looking at powder coating any of the
parts that came with our Triumphs.
Instead I'm looking at the plastic that is used by the Rapid Prototyping
machine I use at work.
It basically uses a laser to melt together layers of powdered plastic from the
ground up. (Yeah, its pretty cool. I'm psyched about this job)
The plastic is essentially nylon and makes remarkably strong parts (it makes
What really got my attention in Nelson's article is the fact that the Powder
could flow at temperatures below 350 degrees.
I happen to know that the plastic I'm using to make parts has a melting
temperature of 383 degrees. I bring the powdered form of it up to over 300
degrees before the laser hits it to sinter it together, and the tiny particles
don't clump together at all at that temperature.
So there you go . . . I've got plastic parts that can withstand elevated
temperatures. Maybe not quite 400 degrees, but then again, I'd be
experimenting with samples anyway.
Which brings me back to my original question: How can I make the powder stick
to a plastic part?
