TOPIC: Wire cleaning

Wire cleaning 2 years, 3 months ago #1107

We manufacture copper coated wire. We need to clean the wire inline before coating. Any suggestions

Re: Wire cleaning 2 years, 3 months ago #1108

If you go to:

and type cleaning steel in the Title Contains box and click on the Submit Query button,you will find an abstract of a paper (ID 2695) titled Cleaning steel wire without acid by Klaus H. Oehr and Reinhold Roth, of the DynaMotive Corp. in Vancouver, Canada in 1995.

The paper presented at WAI 65th Annual Convention, Atlanta, GA and was published in Wire Journal International, May 1996 (Page 100)

If you click on "Detail" you will find the following abstract:

DynaPower is an electrolytic cleaning process that replaces acid pickling for the removal of oxides and lubricants from metal surfaces using ordinary salt water as an electrolyte. The process saves $16.35/ton, generates no liquid effluent, and reduces sludge by 40 percent, as compared with acid pickling which produces and estimated 55 million tons of liquid waste per year. The process produces a more uniform metal surface and the micro roughness can be easily controlled. Other benefits include no entrapped hydrogen to reduce metal strength. The surface is also less susceptible to rusting.

If this looks interesting to you, you can purchase the paper. This is the only reference I have found so far.

It seems that DynaMotive Corp., sold this part of their business in 2002 so you might have to contact them to find out which company bought the technology.

Update March 01, 2006

We learned today that the company we were referencing is:

DynaPower Inc.
3650 Wesbrook Mall
Vancouver, British Columbia
Canada V6S 2L2

Their phone/ fax numbers are:

Tel: (514) 369-4091
Fax: (514) 369-3940

and their web site is:

It is also possible to use a Plasmait plasma surface cleaner:

Are you talking about enamel coating copper wire? When you say clean the wire inline I assume you are meaning between the wire drawing machine or the wire coating machine.

Depending upon the speeds, there are people that successfully use cloth wipes. If the wire is round and large dia. 0.7+ mm in dia. you can use a rope. The important thing about any wipe is that you change it frequently so that you are taking dirt, grease, etc off and not reapplying it.

there are also ultra sonic cleaners that are used usually when processing aluminum magnet wire but I see no reason they would not work for copper.

Another thing is to run the wire through a tube type annealer. You don't have to anneal the wire but you can burn off the impurities, etc. You will need a false atmosphere to prevent oxidation.

He is cleaning copper not steel.

happy new year.

Hi Spectre

I would not make such a strong statement of fact as that.

Since it was posted in the Ferrous Section and since English is not necessarily his/her mother tongue, I just presumed "Wire" was discussing copper coated (clad) steel wire. I don't think that is so unreasonable.
