MONO-SOLVENT SYSTEMS EASE THE SWITCH FROM TRICH
Ultrasonics give TRW Aeronautical pristine pistons
TRW Aeronautical Systems has five Microsolve ultrasonic cleaning systems at its Birmingham factory, finishing steel valve components used in fuel and hydraulic systems of jet engines.
Kerry Microsolve 250 mono-solvent cleaners were chosen to remove excess lubricant and general debris from the aerospace parts. The majority is removed in the first stage, which is also treated with ultrasonics. Finer traces can be removed in the second cleaning stage, and a final freeboard stage allows vaporised solvent to condense onto the component's surface, rinsing it free of any remaining traces of contamination with pure solvent.
Trichloroethylene (trich, trike, or TCE) was being used at TRW Aeronautical in their aerospace parts cleaning. Installing Kerry mono-solvent systems meant that the consumption of trich was minimised, and changes in solvent legislation could be accommodated easily. Solvent emissions are low, meaning that both running costs and environmental impact are minimised.
TRW Aeronautical Systems uses a one-piece flow production technique in its plant, which means the throughput of each machine averages 50 units a day. A semi-automated process was chosen using the Autotrans Single Axis Lift, capable of lifting 10kg and offering an economic alternative to full automation.
