Can SMES reatly coat wiihout prior experiences
and without a Ph.D. physicist? The
answer is: Yes. Numerous examples of
smat[ and medium-sized toot-manufacturers,
regrinders. mold and die makers, injection
motders, machine producers and
even of tool t.aders show thaL integraLion
of coaLing in Lhe mechanical production is
state of the art (Fig. 1) [6 and 7].
SMEs can easily coat
without prior experiences
Can Si\'.1Es produce quality-coatings with
constant composition, [ayer thickness, and

are not coated together with foreign toots
or even with totatty different parts jn the
same batch. 50 the layer thjckness, composifion
and even the choice of coating
does not depend on what are currentty running
in thejob coating centre (Fig. 2). For
S14Es onty compad and flexible coating
units can be considered. These have to be
abte to produce every coating that is avail
abte on the market. At the same time productivity
ofthjs compact machine has to be
high, so that up to six different coatings
can be deposited in a day (Fig.3).sMEs can
also deposit special coatings according to
special apptications or even generate own
brands wjth the hetp of the own in-house
coating, as shown in Fig.4 and 5.
Do SMEs have an answer shoutd the big
job coaters come to the market with
newty developed coatings? The answer:
! The S[4E shou[d be very careful when
buying a coaLing sysrem from machine
