Sliding and demolding coating
TopCoat
Everything has to fit together in the PVD coating process. Our TopCoat works as a stand-alone coating in the plastic injection molding industry or as the perfect complement to our PVD hard coatings in metalworking.
Perfection on top
How does the pacifier come out of the mold more easily? With our TopCoat anti-friction coating: a tungsten-based coating that can be applied directly to the base material or to a PVD hard coating. Like an oil film, it prevents direct contact between the friction partners. The result: the tendency to cold welding is reduced and the emergency running properties of highly stressed components are improved.
TopCoat originally comes from the plastics industry and can also be used as a stand-alone coating for plastics. The coating now also works extremely well in combination with our hard coatings as a demolding aid. We use it very successfully as a supplementary coating for customers who do not use temperature-suitable steels.
A successful example from stainless steel processing: The customer was desperate. During punching, the punch heads or functional surfaces of the punches used were tearing off, even though they were already equipped with a TiCN coating. By additionally applying the TopCoat, it was possible to further reduce friction and significantly improve the plunging and return of the punch.
A successful example from plastics processing: the anatomical shape of baby soothers can be a challenge in the production process. What to do if the silicone or natural rubber (latex) pacifiers get stuck in the mold during the injection process? We have equipped both halves of the mold with TopCoat, which has significantly reduced the plastic's tendency to stick.
