I have found this to be true. I have measured numerous steel springs before and after our zinc phosphate process and they always weight slightly less afterwards.
Aidan,
You are correct about the shotpeen process. I did not describe it correctly. Thanks.
Berkshire, dry ice blasting is something we have discussed for many different applications here. For this particular job it was dismissed due to footprint constraints but I would love to see what it...
Thanks all.
EdStainless, we use vib bowls for many other applications here but for this application we need an inline system, not a batch type system. The cleaning station is incorporated into the manufacturing cell and we would need more than one large vibs to keep up with the production...
Hi swall,
They are fairly big as springs go. Approximately 7" long by 2.5" diameter.
We were wondering if an ultrasonic would loosen and remove the residue. Now we know it should. We are looking to order a small unit to try it out. If we use one for our production requirements I think it...
Hello all,
We manufacture springs and a couple of our jobs require shotpeening. The parts are made from Oil Tempered Chrome Silicon wire. We send the parts through a spray wash cabinet followed by a heated air dry after shotpeening but some shot residue remains and is causing us to fail...
Well, anything is possible. We never had made our own before. We have two other processes where we use DI water that we purchase - for our salt spray cabinet and our EDM machine and never had a problem before so we thought this application wouldn't be any different.
Thanks for the quick response EdStainless. The light has gone red on the replacement tank. The conductivity was a little over 300 when I noticed it red checked the reading.
Also, do you think the high chloride reading will be a problem on our steel parts? I am thinking we need to empty...
Hello all. I am looking for some advice with a DI application.
We have a process that includes quenching small metal parts. The quench solution contains a sodium nitrite inhibitor that provides corrosion protection. We purchase DI water in tanks from a local water treatment supplier. In...
To me, the only logical choice is red for stop, green for start but I am dealing with a engineer who would like me to program a machine just the opposite. He wants the start button to be red and stop to be green. I think it will cause all kinds of confusion for the operators who have years of...
Is there any standard that states Start and Stop buttons on a touch screen must be a specific color? For instance, if I have a button labeled cycle or machine stop, does it have to be red?
We recently received some Oil Tempered Chrome Silicon spring wire that appeared to have some surface contamination. Our vendor stated that all wire goes through a molten lead quench and that it must be lead that was not burnt off in the subsequent burn off operation.
We had an outside lab...
Hi all,
We have a small 316 SS tank that we use for passivating small stainless components with a 50/50 mix of water and Nitric acid 42BE.
A new employee changed out the tank last night and added Hydrochloric acid to the water instead of Nitric acid. By time the acid was pumped out, it had...
I was using the wrong calculation when looking for a mag meter. I found a few that I should be able to use with my current plumbing design.
Manholes, flumes, wiers were all suggested and would work, but I need something small as space is very limited and we also want something we can install...
Our horizontal run would be a full pipe but not the vertical. I have checked Endress + Hauser, Signet and Omega and all state the effective measuring range for all of their models is from about 14 gallons per minute and up. Omega did have mini models but they went from 1 gallon per minute up...
