Powder Coating

Postby DuncaninFrance » Sun Mar 11, 2018 8:27 am

I was just looking at some Videos on YouTube about Powder Coating - very interesting.
I have everything I need to try it except the paint powder,
I looked on Harbor Freight as they seem to be a common place to source the colours.

16oz bottle of Red = $6,99 +p&p.
Amazon UK - SAME item $85 :shock:

Amazon UK $$...... :shock:
That exact same brand/item on Amazon US is $18 + $6 shipping.
Although Harbor Freight is known for home use items, not professional grade.
Most all their stuff comes from China...... they are the Walmart of tools........ :lol:

A great result today.......
I contacted a company in the UK last night by email to get their non premium phone number - https://www.electrostaticmagic.co.uk/ and spoke to a lovely lady who was able to sort me out ( impossible I hear someone shout :roll: )

They ship to all parts and so I placed an order for a trial bag of Red

https://www.electrostaticmagic.co.uk/collections/gloss-bag/products/dark-red-gloss

Postage for 500gms would be £26 tracked ( this is the same up to 30kg I think) so for the test I sent it to a pal in the UK for posting on.

Cost; £11.98 / $16.50! AND of course, they make the stuff. She asked me to let her know how I got on which is great after sales :razz: :razz:

Powder arrived today,
Here ar images of the kit I have got together to try this process.

POWDER 01.jpg

I am going to try 50 cast bullets in .303 Sporting and see what happens. I shall make a photographic record as I go along.
There are lots of YouTube videos out there but they seem to generalize. We shall see.............

You are going to powder coat cast bullets??? What is the advantage of doing that???

If you heat up the lead bullets in that toaster oven as part of the procedure won't it maybe soften the lead up enough to get the bullets out of round?

According to the videos I have seen it removes the need for gaschecks and lube plus it prevents leading. Accuracy is improved too.

As these are a lead & wheel weight mix the melting temp is around 600ºC. The oven temp for the 'baking' is 200ºC. I doubt there would be a problem - it certainly doesn't feature in the videos or comments. Once coated the bullets can pass through a re-sizing die without lube.

First result was not a good one.

Here is the process.
POWDER COATING FLOWCHART.jpg


First stage went OK
POWDER 03.jpg


Bullets did not coat as expected.
POWDER 04.jpg


I only baked eight to see how the powder stuck - if at all - and it did.
POWDER 05.jpg


SO :roll: Next try on Sunday.
1) Clean the bullets first in case grease is the problem.
2) Miss out the pre-coat warming.
3 )Agitate much longer to create better static :)

Update:-
Having tried all possible ways I can think of to get the powder to stick to the bullets and being unsuccessful I obtained a Product Data Sheet from Harbor Freight and sent it, along with my observations on the problem, to the powder supplier in the UK.

I spoke to them yesterday on the phone and the only possible difference between their powder and Harbor Freights is that the HF powder contains a 'Nasty' which theirs doesn't ( EU Laws probably) . They confirmed that they sent various colours to some reloaders in Scandinavia who have not complained.

They have offered to do some trials for me so today I sent off a selection of cast bullets for them to test. Will wait and see what happens.

I spoke to ElectrostaticMAGIC on Friday to see if there had been any progress with the bullets I sent them last month.

They were very apologetic and said they had been very busy with a new product launch but they would put my problem at the top of their to do list.

Today I received an email with the results of their trial. They look very good. They are gun coated as opposed to electrostatic coated.

They are posting them back for me to assess.

Well the bullets arrived yesterday and the coating is fantastic.

I worked this idea out for spay coating. The bullet point does not engage the rifling but the base needs to be coated to protect is as gaschecks do. This set up should do it although I am still thinking about it.

I shall buy a a powder gun but because it will cost about £28 / $38 to ship it I will get our next guests in the gîte to bring it over for nothing! Unfortunately that will not be until July 8th but I can wait.

This morning I did a test on the materials that I hope to use for the powder coating system.

The plate was put into the electric oven at 200º C / 400º f and baked for 15 minutes.

TEST 1.jpg


As can be seen the bullets have all canted over a small amount.

Once the plate and bullets were cool I removed the bullets from the Blu Tack. As can be seen they came away cleanly and the Blu Tack was still malleable.

TEST 2.jpg


So, it looks like I may have developed a system, all be it not one for bulk production but enough for my use :)

OK, so here we go.
First make the support plates from 8 mm thick aluminium..

Drill 5 mm dia holes

PLATE IDEA 3.jpg


Use a 22 mm drill to clean the back of the holes.

PLATE IDEA 4.jpg


Counter sink the 5 mm holes on top using a 10 mm drill

PLATE IDEA 5.jpg


Holes for 100 bullets.

PLATE IDEA 6.jpg


To be continued :cool:

Next stage was to set up a plate to take some .303 British using small inserts of BluTack.
60 now ready to coat.
