powder coating jigs - how to clean?
What is the best way to clean powder coating jigs used in a high volume production environment? I may be talking to a company soon (under my
consultancy business) who have a furnace at 450degC running all year round where they heat the jigs then sand blast them. Sounds expensive to have a
furnace running for such applications. Just wondering if anyone else works in a powder coating company that have a more cost effective solution. I
only have experience of Electropheritic wet paint dip plants, you dont get a high build up with those. The company makes automotive parts so will need
to have a high quality process to get approved via a process change request.
Only option i can think of is to find a local company that does the cleaning but i guess this has to be offset against needing more jigs so you can
send a batch out for cleaning.

shotblast them with heavy steel grit, should rip though it without preheating.
Do it on a "kanban" basis with a company with a "wheelabrator" machine (centrifugal blaster) i.e. just cycle a set of spare
jigs out to them
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

can the jigs be coated with something that the powder does not stick to?

Just need to find the same stuff some manufacturers seem to coat
their chassis with before they send them off for powder coating!!

Leave them nice and smooth and spray them with thin oil same as it comes from the steel stockholder.

Recently had my chassis shotblasted and was advised by the shot blaster to remove as much of the powder coating as possible before getting it blasted
. Paint stripper worked well

I'll back this up.
We use a wheelabrator at work for shot blasting cast iron castings. Used with 14g steel shot it makes short work of anything you put through it.
