Water rinse cleans brass products
Trials have confirmed that water can now be used successfully to degrease components using water rinse iat 75 deg C so the components dry rapidly after degreasing.

Lubricant additives benefit SS tube drawing
Work to significantly enhance the lubrication of highly chlorinated tube drawing lubricants - and deep drawing - has lead to the discovery of additives which offer considerable performance benefits.
Lubricants smooth severe cold metal reductions
A range of lubricants can be applied as a coating for the most severe cold reductions in stainless steel alloy, and titanium and are suitable for the most arduous operations.
Like many engineering companies a low cost way of changing away from TCE was required.
The cost of installing a hermetically sealed degreasing system was totally prohibitive.
Nor was there was no way to reduce consumption to less than 1tpa.
Having studied the company's way of working and its processes, John Neale considered that lubricants could be selected, which would either wash-off in water or clean burn off in certain hot processes.
Samples of new technology water rinse-able products were supplied to the company.
The company had mentioned that they had trialed several of this type of product from their previous supplier with no success.
John Neale explained that the use of standard soluble metal-working fluids is not suitable for water rinse degreasing.
The lubricants have to be removed with no agitation and simply dissolve into the water, which does not happen with most water-mix lubricants.
Trials have confirmed that water can now be used successfully to degrease components.
The water rinse is operated at 75 deg C so the components dry rapidly after degreasing.
Components are cleaned to the company's full satisfaction.
Samples of thermal degreasing fluid were supplied so that the customer could avoid degreasing altogether on operations where hot processes followed.
Careful selection of lubricant raw materials again gave total success.
Now the company can avoid degreasing on a significant amount of production and so prevent a 'bottle neck' at the degreasing plant.
John Neale has many lubricant solutions to help customers remove TCE from their process.
