My boss recently sold a division of our company, and is fully investing its profits into a brand new powder coating shop from the ground up.

In my area, there isnt any competition locally......

I was wondering if there was anyone out there that works or has experience in powder coating that would be willing to share any information for a start up?

It seems that "we" are going to be involved in this project of his....and Just want to do it right. Any information or advice would be EXTREMELY helpful!!

Make sure the donuts get an even coating and that they don't sit and get soggy. That makes the powder gross.

Apply powder in moderation, too much will make you look slutty.

What are you coating with powder?

There's a modern way to furnish walls, instead of wallpaper or just painting. It's done by preparing the wall with some kind of glue and then blowing some kind of plastic powder to it, then sealing it with transparent paint.

Washable and looks interesting.

With powder coating you're probably mean something different?

I wish they would make cars with that kind of finish. Instead of all those shiney crap that reflects sun and you can see all dirt on, the color never looking the same depending on lighing and viewing angle, the dull view of powder coating could look really cool. I think the military uses something similar, I just don't like those shades of green, for cars at least.

Our chassis supplier is starting up a powdercoat operation too. I'll pass on any issues they share with me.

From what I've heard:
Powder coating is:
A) Better for the environment
B) Lousy finish (longevity and durability-wise)

I own a "powder coated" painted car now, and I can attest to item B) (or maybe its just inferior German paint? Shrugs)

The wife bought two white metal patio chairs from a discount retailer last year. After about 2 months in the elements, we could no longer use them because the paint was starting to come off. Now that I think about it, it was like the paint was coming off as a fine powder. Was this a crappy powder coating?

Could be that they were not fired enough? Or the metal preparation.

Hiya,
Used to work allover UK installing finishing plants etc

Powder plants eg........

start/degreaser cleaner/rinser/drier/powder booth-s (charged electrostatic) then into the bake oven/end

On most well more like 99% of plant installs we did the owners etc opted for a "wet" (wet spray system also)
This enabled mass powder coating at efficient-cheaper rates per item and switched to Wet type when the runs were uneconomical or very small etc

We worked in a variety of major companies eg Ford/JCB/Newsift/Lawrence Scott

Some plants were huge i mean 100ds of foot long (Lawrence Scott in norwich was a mass of factory roofs with 1 ulmighty open floor space, Had a rail system in there to shift stuff around, Always rem when we were waiting for some parts and we would see who could push a wagon the furthest from a 6ft run up lmao)

Done kilns/spray booth (cars etc)

Moved whole plants from england n shipped em to belfast n portadown etc

Basic is....Start = hanging part on some form of hook or jig on a overhead rail system, This chaining moves at a set speed (real slow so powder don't shake/drop off etc) (1.5hrs sat on a jig going around lawrence scotts new plant (i was nominated to go thru all the processes to check for probs lol))
It will make its way through a "pretreatment-degreaser-rust remover" mix of various chemicals, Some setups we installed had say 4 acid baths as we called em he he, It will then go thru at least 1 dryoff oven or maybe a few depending on what the plant was mainly designed for, It then goes to powder/wet station, Powder charged, Generally you aim and the gun/s spray the powder out and the opp charged part/s attract it (we had fun also messing n seeing who could get the furthest away n still coat stuff lol) From here it makes its way to the bake oven, this on average plants is like 80ft long, In there the powder is heated etc and then it returns to a exit/pickup point or to the start (depends layout etc as i say)

That's basicly the plant

Wet as i say is used instead of powder station if required

Got a plan here of a small plant we did in scotland well i think it was scotland, We did that many i lost track

After getting used to working "away from home" i loved the job and the money was great (though the hotel bar took a hefty slice lmao)

Any more info just ask

Mickey it sounds as though

A: too short a time in bakeoff oven or
B: bakeoff oven temps too low
C: mix of both lol

I work for ITW Industrial Finishing, who owns in the finishing group Binks, DeVilbiss, Ransburg and Gema Powder equipment
Drop me an email and I 'll see if I can hook you up with someone from Gema.
PS Very good overview Defiance, just like with wet systems powder coating can have its problems. Anyone check out Orange County Choppers and some of the bike parts they powder coat, absolutley incredible stuff.
