The RUBIG Group is consolidating its Laser Technology and Surface Coating divisions with its latest subsidiary, RUBIG Technology. This increases the field of application for lightweight parts at the same time. The surface coating technology is individually adapted to the customer‘s requirements. And RUBIG has even found a formula to fight viruses and bacteria.
Materials typically used in lightweight construction, such as aluminium, titanium or plastic, have special properties that make them particularly attractive compared to steel: density, specific strength and suitability for mass processing are just a few examples. On the downside, these materials have a few disadvantages in terms of their surface wear resistance. And this, in turn, restricts their potential uses in the component application. At RUBIG Technology, the latest addition to the RUBIG Group, the portfolio focus is on growing these fields of application.
Using laser deposition welding or laser alloying, hard material particles such as silicon and tungsten carbide can be integrated into the surface. These highly durable materials significantly improve the resistance to adhesive and abrasive wear and make surfaces even more stable than that of steel. The hard material phase components are adapted to the customer‘s needs as a function of the respective type of stress and the production process. This ensures that the use of lightweight materials is optimised in terms of machining, resources and stress.
PVD – Physical Vapour Deposition – is a surface coating technology based on physical impact. PVD coating systems are wellknown for their excellent wear resistance and are therefore often used for machining tools. But they are equally useful for the surfaces of plastics. RUBIG Technology tailors both the design of the coating system and the coating recipe specifically to suit the plastic components or meet concrete customer requirements. Standard wear protection coatings but also functional, decorative coatings with a variety of coating compositions can be implemented.
Corona taught us a great deal about the presence, role and spread of viruses and bacteria and clearly showed us the limits of our infrastructure. Since the beginning of the pandemic, the RUBIG Group has concentrated on improving this infrastructure with new technologies. RUBIG Nitropep is a non-toxic coating developed for metals and plastics that contains disinfecting and antimicrobial agents such as chlorhexidine. Viruses and bacteria are killed within minutes after contact with a surface treated with Nitropep. Additional actions such as light irradiation are not required.
Targeted use at neuralgic points such as entrance doors to kindergartens, schoolsor care homes can effectively reduce the transmission of pathogens. The coat is firmly bonded to the surface of the coated object and can only be removed mechanically, i.e., by destroying the surface. It is non-hazardous in terms of sensitisation and cytotoxicity. An accredited Austrian laboratory has demonstrated the effectiveness and non-hazardous nature. Chlorhexidine is also approved by ECHA as an active substance and in the pertinent product groups in line with biocide legislation.
