Deep Drawing Aluminised steel.

What is the motivation for changing a process which presumably already works?

I expect it's cost, can you recover/reuse the oil?

The polythene wrap sounds a hideous idea to me.

What sort of pans are you talking about? Cooking pans? Sump pans?

Thanks for you reply. The polythene idea sounded wild to all of us too, But i can assure you that one of our competitors uses this method with great success. The only drawback for us is that we have hit a brick wall in finding a supplier.

i think you can use waterbased lubricant instead of oil, it canbe wash very easy. i konw milacron have this type fluid for forming.

Great answer WWKAYAKER welcome to CR4

Thanks Milo! It feels good to finally get to offer something to the message board.

Wow. Thanks for your reply and the information looks good but mostly explains coatings on steel. The one thing that I am still struggling with is getting hold of polythene which is wrapped around the blanks prior to deep drawing. The polythene is approximatley 0.14mm in thickness and is clear I assume it must come in a roll which is then cut up and individually wrapped onto each blanks.

Many thanks

We deep draw aircraft metals all the time ( inconel, hastx,cobalt and so on) we believe it or not spray blue dykem on the parts and then coat them in drawing wax.

It works like magic.

Thanks. That sounds interesting, do you think that would work on aluminised steel ? if so were can I learn more about these products ?

Have you ever thought about hydroforming?

The company I work for is very cost sensitive in these competitive economic times, and as I don't have any idea what cost is associated with EasyFilm, I just want to offer that we currently use water-soluble oil when drawing aluminized steel.

We have had great success with the water-soluble, and the flexibility of being able to change the water/oil mixture has allowed us to minimize our supplier base and stored quantity of lubricant, as we are able to use this over a wide spectrum of stamping and forming/drawing operations.

I am the president of an engineering consulting company in the US that specializes in [development/commercialization of] metalworking fluids. We have just introduced an environmentally friendly dry film that allows radical shapes (deep draws) to be easily formed with exceptionally low coefficients of friction. It is typically sprayed or roll-coated at the mill and no further lubrication is required when processing. It is easily removed and residual needs little treatment. Would this be of interest?

We have a superb dry film lube for drawing aluminum, high alloy steel etc. It is setting a benchmark for this application wherever it is being used. If interested you can e-mail me at the source for this material at m.dorbeck@galleonintl.com
