With research and development center has developed a range of technologies, processes, coatings and coating, are able to provide solutions to most problems related to friction, corrosion, abrasion, in automotive, aerospace and construction material during the transformation / pressing, extrusion. ... / CERTESS under the brand name is now most common coatings based on TiN, TiCN, TiAlN, TiAlCN, CrN, but also not as advanced coatings based TiBN, CrXnY (with the possibility of any adjustment ratio X: Y) and DLC (possibly adjustment of any ratio of carbon in the form of graphite in the form of diamond).

Mechanisms and problems of pressing: When injecting plastics are facing many problems: - Zadieranie corrosion and friction of moving parts of some forms / ejectors, moving pins, tractor parts, guide rails, etc. ... - Fatigue, abrasive attrition / eg. through fiberglass /, corrosion / eg. through decomposition or condensation of chloride polymers, the effect of diesel / combined heat and pressure acting on gas in closed areas / In addition to these aspects which reduce the life forms we will mention two more critical parameters: - Forms the feed rate in most cases be directly proportional to the coefficient of friction material / plastic / forms on the surface. This directly affects the duration of the pressing cycle and hence the cost of a cycle. - Very important and well known phenomenon is the interaction between the surfacethe temperature should not exceed 150-200 ° C, occurs when changes to the mechanical properties of forms. How effective is proving just PVD coatings CERTESS X CERTESS DLC, PEMS ® technology-applied at low temperatures. Some applications are already in practical use.
Summary: The above examples demonstrated the advantages CERTESS coating applied to the molds and tools for plastic injection, rubber and aluminum: - Form filling easier - Reduce the frequency and forms of treatment by - Reduction of machine downtime - Improving the quality of the surface forming member / cast
