Powder coating of moulded (Nylon 6 GFR) components

I'm looking for process information and design guidelines (preferably
practical experience) with this type of finish.
I've tried to Google it but doesn't seems to have much info at all.
Your help would be appreciated

Why would you do this? Nylon can be colored during molding. Powder
coat is typicall fused in an oven at temperatures that would probably
destroy the nylon part.

 

Google is useless...too much info, little if any of it hits the target.

You might try www.globalspec.com and www.kellysearch.com to find suppliers
of powder coating equipment and services, maybe their websites have some
links to process info. I seem to recall that there is a powder coating
industries association of some sort, might give some useful links. Googling
THAT may get you something useful. You could try Amazon.com,
barnesandnoble.com, booksamillion.com and purchase a technical reference.

 

I looked into this a couple of years ago. I'll try and dig out the
details - it is possible onto plastic however I am not sure about
nylon.

The project was dropped because the plastic syupplier was not happy
with the consistancey for supply . The powder coat would work OK on
some batches but not others so there was too many rejects.

I know it sounds bizarre - to pay for something twice - but the
technique has been developed to get a consistant surface finish
accross components and the supplier I was talking to was supplying to
the Auto industry.

Nylon is a high temperature plastic. If the powder had a low fusing
temperature or was a heat cured epoxy then this might make sense. One
drawback might be that the powder would limit the high temp properties
of nylon. As I think about it this might be a good process to color
nylon when it is fiber filled. I never liked the look of my car door
handles after a few years of sun. It exposes the filler.

 

Eric,

This month's issue of "Paint & Powder" is all about "powder on
plastic" check out their website paintandpowder.com you may find the
information you are looking for.

I was looking at street furniture with a filled plastic for strength
and to match in with all the powdercoated steel and aluminium.


The problem was getting the conductivity consistant to get a good
attracion for the powder. But it looks like it may have been solved
after just reading Paint and Powder.

Its quite a usefull process to keep in mind because for low volume
items like street furniture, on each job the architect wants his own
colour and it is just not economic for coloured plastic production
runs. So we were planning on buying in a decent amount moulded in
brown and then colouring to order.
