Medical technology combines engineering sciences with the field of medicine to form a unique technological focus. This focus aims to improve diagnostics, treatment, therapy, care, rehabilitation and quality of life. The field is characterised above all by the close interlinking of products and services and a high level of research and development activities. Challenges are posed by comprehensive national and international standardisation as well as various regulations at state level.
RÜBIG is MDSAP certified in the field of vacuum hardening and has extensive knowledge of special steels, such as stainless steels 1.4028, 1.4034 and 1.4021. A well-equipped laboratory and an R&D team experienced in medical technology enable efficient cooperation and development work with customers. The results of these development activities are special processes and coatings.
Scalpels, retractors, wound hooks and all other surgical instruments and surgical equipment are exposed to particularly difficult conditions during their use. At the same time, they have to meet high quality standards in terms of hygiene and strength. Resistance to blood and acids and excellent cleanability have top priority. This implies high wear and corrosion resistance and durability of the instruments and naturally a corresponding biocompatibility of the surfaces.
The broad portfolio of R.VAC+® vacuum hardening processes offers the right heat treatment for these demanding precision parts and guarantees highest reproducibility of results.
Preparation and dental instruments are subject to tremendous wear. The same applies to their individual components such as turbine angle pieces and turbine heads, components of dental drills, couplings or FG shanks. Just like surgical instruments, they are subject to strict hygiene regulations and must be resistant to blood and acids. The R.VAC+® vacuum hardening processes provide individual components with the necessary core hardness, fatigue strength and basic wear resistance. Components requiring further heat treatment in the surface layer are nitrided in-house (PLASNIT® plasma nitriding or R.NIT+® gas nitriding processes). This further improves the wear properties of the surface.
Thanks to advances in medicine and technology, people with disabilities can made be more independent, more mobile and thus enjoy a better quality of life. Prostheses, orthoses, splints or even wheelchairs can now be adapted to individual needs and environments. In order to guarantee this adaptability and user orientation, the right heat treatment must be ensured during the production of the equipment. Axles, shafts, joints – each and every component must allow the user of the end product to pursue everyday and leisure activities with the least possible restrictions. RÜBIG offers a wide range of heat treatment processes to suit each individual part and stress type: Vacuum hardening (R.VAC+®), case hardening (R.Carb+®), plasma (PLASNIT®) and gas nitriding (R.NIT+®) and various surface coatings.
OEMs and suppliers to the pharmaceutical industry are confronted with the engineering challenges of making production steps more efficient and ensuring a high level of quality at lower costs. The service life of these high-precision machines for end applications ranging from weighing and granulating to screening or mixing is a significant decision criterion. Correct heat treatment of the various components or component groups within these machines can provide the decisive competitive advantage. Reliable protection against wear and corrosion, the possibility of effective and clean disinfection or, ideally, the application of biocidal surfaces are basic requirements for every OEM. Vacuum hardening (R.VAC+®), case hardening (R.Carb+®), plasma (PLASNIT®) and gas nitriding (R.NIT+®) or various coating processes support our partners worldwide in meeting these requirements.
Hard coatings offer maximum wear and corrosion resistance as well as excellent sliding properties. Furthermore, customer-specific colour schemes can be assigned to them, enabling the end user to identify coated parts quickly and clearly. PACVD coatings (Plasma Assisted Chemical Vapor Desposition) are applied plasma-assisted by physical deposition. The coatings are either carbon- or titanium-based and are also offered in the DUPLEX procedure, i.e. they are plasma-nitrided in advance. This annitration of the surface significantly improves the adhesion of the applied hard material layer.
DLC Xtended® (Diamond Like Carbon) is a carbon-based amorphous layer alloyed with silicon and hydrogen. Their high chemical resistance not only guarantees the highest level of corrosion and wear protection among all hard material layers, but also prevents the absorption of foreign substances in the surface. In addition, it impresses with its perfect feel and optics with shiny metallic and clean surfaces. Combined with a PLASNIT® plasma nitriding process, a surface hardness of up to 1.500 HV can be achieved.
