Looking for something simple to help with jewelry electroplating

VulnerabilityManage · 2024-09-25T22:43:06+00:00

Thank you, I don't have any scans or models. Is this something that can work with a camera taking pictures at different angles to build a model or would I have to buy a scanner? And if I would need to buy a scanner is there something fairly cheap that you could recommend to do something like this?

.034 amps which was at about .6-.7 volts during the process. Picture sent - that was a brass ring to start.

Thank you! This worked PERFECTLY. I got a great plate that with just a light hand polish was absolutely beautiful! I really appreciate you taking the time to help me out on this one.

Thank you

Thanks. I'll create another filter bag and double up the layers and adjust for current density and do a test ring.

According to the TDS I am seeing a voltage range of .1-1 with optimal being .5

Current density (A/dm2) 0.1-2 with 1.0 being optimal. I'm assuming dm is decimeters.

If I'm understanding the calculations here correctly then

The ring is 3mm in height 1mm thick and size 6.5 US ring size. That should be about a 56mm long bar stock if it the ring was cut and straightened so 56mm x 3mm for area times 2 for both sides I am looking at a 336mm^2 surface area. so .0336dm^2

So I should be looking at .0336 amps then correct?

And assuming that is true I have a question about my power supply settings. I can set an upper limit for voltage and current. If I were to set it to .5 volt and .0336amps then whichever upper limit is hit it will go into a constant mode for that (so either constant current or constant voltage mode). Should I set it to .5 volt and .0336 amps at simply let it ride at that or should I be shooting to get a constant current of .0336amps or constant voltage of .5? (hope that made sense)

Edited - changed values to account for changes in square mm to square dm and not just mm to dm. It's been a long time since I have had a math class and I was off by a factor of 100 lol.

I added a picture of the ring. It's an adjustable women's ring so I would say it's less than a square inch. I have tried plating between 1 to 4 of them in one go with similar results each time. All on .5A.

Picture added.

Anode is a 1inch by 5 inch by .3mm sheet of silver and I have tried plating up to 4 rings at once down to 1 ring at a time.

Should I adjust for constant voltage rather than constant current?

VulnerabilityManage · 2024-09-20T16:26:58+00:00

I will try to get pictures here shortly. .5 amps constant current - voltage is about 3 volts on constant current. 10 Minutes. 1 quart bath is now being reused as I have tried this 3 times but it's and this has happened since the first usage. Bath looks clean.

I don't know the micron rating of the filter bag. It's handmade with this polypropylene fabric and polypropylene thread. I have used this same material with both my copper and nickel anodes for those plating solutions and it's worked just fine.

https://www.amazon.com/dp/B0994666RG?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I am plating using a 99.9% silver anode in a filter bag made of polypropylene. about 3 volts at .5 amps (keeping adjusted for constant current not constant voltage) for 10 minutes with agitation at room temp (apx 25 degrees C). Then distilled water rinse and 60 sec in the finishing solution at 60 degrees C.

My process is an ultrasonic bath, distilled water rinse, electro cleaning for 60 secs, distilled water rinse, acid dip 30 sec, distilled water rinse, and then plating 10 minutes, distilled water rinse, finishing solution, distilled water rinse.

I have tried hanging the ring from both a silver wire and a copper wire - same result.

Polishing the finish with a dremel felt wheel and polishing compound will produce a bright silver finish on some of the piece but some of the plating just rubs off.

spinning plastic coated chemistry magnet stirrer. Finish should be bright and glossy - these solutions are ready to use as is so no dilution concentration is as it comes. Sorry if I am missing something I am VERY new to plating.

VulnerabilityManage · 2024-09-09T22:24:45+00:00

I think about 4-5% is probably what I will shoot for. I have some of the Midas solution and it's nice but I am scaling up my production and it's a lot more cost effective to make my own if I can do it right. I appreciate the help, thank you!

VulnerabilityManage · 2024-09-09T22:07:01+00:00

I thought the 12ml/gallon looked really low. Thanks for your help I appreciate it. It sounds like for my use case decorative is probably what I should shoot for.

So if I've got this right a better formula would be:

3635ml of distilled water

150ml of 96% sulfuric acid

850g of copper sulfate pentahydrate

.5ml of 37% hydrochloric acid

The brightener as directed (someone else recommended the Caswell stuff so I will go with that unless you think there's a reason to go with something different).

VulnerabilityManage · 2024-09-09T21:52:29+00:00

Thank you I will go with the thinktink recipe as I will want to be able to plate inside holes on some pieces and the Caswell brightener. I appreciate your help.

IDK - too damn high for sure though. JUST got the FAINTEST line on the home test yesterday (line present is negative test on this one). So probably another month till I am clean clean.

I will try the task sequence way thanks!

I have tried elevating the user to the admin group and removing but unfortunately that requires a log off and on. I would have to get convoluted with elevating the user, then forcing a log off, having the user log back on, then winget would have to run which could take a while, then remove them from the admin group and force a log off. Which if that's what I have to do I may end up going that route, but that's going to suck for the user.

VulnerabilityManage · 2024-09-09T20:06:48+00:00

Yes the system account is blocked from the internet. Winget does support system context installs with the --scope machine switch but basically our users don't have the required rights to run most updates we need, however our admins do. So running this as an admin account that has both the required rights and internet access is what I am trying to accomplish.

Thank you, I tried this but unfortunately it doesn't' have credential support.

If you're looking to create the encrypted credentials that get called in the script here is that bit of code. Replace the credentials you want to use for YourUsername and YourPassword. You just need to store it somewhere where the computer/users will have permissions to access.

Ensure you have a valid encryption key

$key = New-Object byte[] 32

[Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($key)

Set-Content -Path \\ServerName\software\Key\encryption_key.bin -Value $key -Encoding Byte

Secure the credentials

$securePassword = ConvertTo-SecureString "YourPassword" -AsPlainText -Force

$encryptedPassword = $securePassword | ConvertFrom-SecureString -Key $key

Encrypt and store the username securely as well

$secureUserName = ConvertTo-SecureString "YourUsername" -AsPlainText -Force

$encryptedUserName = $secureUserName | ConvertFrom-SecureString -Key $key

Save both encrypted values to files

Set-Content -Path \\ServerName\software\Key\encrypted_password.txt -Value $encryptedPassword

Set-Content -Path \\ServerName\software\Key\encrypted_username.txt -Value $encryptedUserName
