Degreasing and cleaning large components
Turbex has introduced an aqueous washing machine for degreasing and cleaning large components and it can take a load of 800kg measuring up to 900mm high by 1.4m diameter.
Coating reduces aerospace alloys wear by 75%
Tecvac's Nitron Flight coatings in comparative wear tests reduced abrasive wear by over 75% and can be applied to titanium, steel and advanced alloy surfaces.
The system also delivered improvements in surface finish, with dramatic reductions in sputtering and the elimination of inclusions in the paint.
3M's Paint Preparation System (PPS) is an innovative new type of dispensing system designed to reduce paint wastage, improve finish and dramatically cut solvent consumption during the spraying of chromated primers onto aircraft parts.
PPS is a modular dispensing system that comprises reusable plastic cups and disposable, flexible liners and lids.

Solvent cleaning machine removes all cutting oils
Industrial component washing machine is intended for machine shops using a combination of neat cutting oil and high-additive oils with a mixture of solvent-based and aqueous constituents.
Paint or primer is mixed in the liners within the reusable cups.
The system, which contains a built in filter, then attaches directly to standard spray guns.
During use, the liner collapses, ensuring maximum paint utilisation.
Once empty, the liners are discarded, eliminating the need to clean the system with expensive and toxic solvents.
PPS works with both gravity-fed and siphon spray guns.
Currently under evaluation with several major UK aerospace firms, the PPS system has proved itself to be particularly appropriate in aerospace applications, where chromated primers are very difficult to clean, while used paint and contaminated primer present a significant environmental danger with associated high handling and disposal costs.
"We have been working closely with the paint shops of the major aerospace manufacturers for some years, and they are already big users of our tapes, films and abrasive products," says David Humphries aerospace key account executive at 3M.
"When we brought PPS onto the market we realised that it could have huge benefits in the sector.
All our trials so far have borne this out and the painters love using it too." PPS has been developed by a 3M R and D team in the UK.
Its first applications were in the automotive sector, where savings in paint and solvent, combined with the ability to rapidly switch paint types and colours without time consuming cup cleaning, have already delivered dramatic cost savings and productivity benefits.
