We now have a new process for applying anti-friction coating to small
diameter pistons for air conditioning compressors and small engine pistons such
as those used in gardening equipment like a chain saw.
Unlike conventional application methods such as spraying, these systems
require no masking of the part to be coated. With our selective
application method, even the top land area of a small piston can be coated with
an anti-friction coating. This cannot be done with spray applications
since the top of the piston must first be covered with a masking boot to keep
the material from going into the ring groove. Obviously this boot itself
is sprayed, wasting the anti-friction coating.
In the spray method of application, pistons must be masked prior to coating
and the boots removed after the curing process. This also will waste
valuable manpower, not to mention the chemicals needed to clean the masking
materials for re-use. But then again, we did mention it, didn't we?
That's because our new process has nearly 100% utilization of the
anti-friction coating material. No masking. No over spray. No
manpower to put the boots on or take the boots off.
As show above, both ends of an air conditioning piston
(raw part) are coated without masking
or over spray.
Small diameter pistons with and without top land coating.
No spray, no screens, nearly no expendable tooling, no V.O.C. or air
