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 cotor? In the own coating-shop the tooß 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: !

Mitting of gears with conventional and nanocomposite coatings, shorter delivery time than job coaters normally offer (2 to 14 days)? With best logistics and express-service job coaters cannot coat most urgent parts in hours. Delivery time for coatings can be reduced to 24 hours The typicat time of detivery is a week (job coating for SMEs) which can be reduced to 24 hours (in-house coating). Through the jntroductjon of a minimum order quantity job coaters show more and more that they are not actuatly interested in sma[[ customers. The total of needed toots has to be two to three times higher than a weeks suppty because of job coaters. Therefore inhouse coating can reduce storage costs significantly. There is a risk for damages or mix-ups at packing and unpacking to and from the job coater to occur. With in-house coating these activities are unnecessary. Experience shows that personnel costs of in-house coating do not exceed costs those for logistics of job c0aters. But what about the foltowing question: Does the company have probtems with manufacturers which run job coating centres in the same country. He has to MANUFACTURER , cobalt-leaching at recoated toots?
