  2. 2. BALINIT® coatings for tools (exception = Oerlikon Balinit Hartec) Cutting Plastics processing Punching/ Die casting forming Mould protection Wear resistance Tool life Tool life Shorter cycle times Productivity Dry running Moving elements without Oil / grease Wat zijn PVD coatings ? Uiterst dunne keramische coatings. Anders dan bij galvanische technieken zijn de eigenschappen van de afzonderlijke bestanddelen niet meer aanwezig!!! Niet alleen de vereiste gladheid of structuur van gereedschappen wordt geseald met deze deklaag. Eigenschappen als corrosiebescherming, slijtageweerstand, lossing en matrijsvulling worden stuk voor stuk positief beïnvloed. Last but not least is “dry running” in veel gevallen (medisch / food) een keiharde eis. Physical Vapour Deposition  Are attached at temperatures between 200 and 500 °C  Thickness of the coating typical: 1-16 µm Standard : 31 µm  Strong adhesion of the coatings  High hardness and low coëfficiënt of friction. 2
