Duplex treatments with different coating combinations.
CemeCon Scandinavia is a specialist in physical vapour deposition (PVD) and develops, produces and offers advanced, wear-resistant ceramic coatings for medical devices.
The company is a coating competence centre founded on two decades of knowledge and technology from university and institute research.
PVD coatings for medical devices and parts
CemeCon Scandinavia offers a wide range of PVD coatings, each with unique features tailored to specific applications. With the right surface treatment, the company can solve many production issues caused by material failure and reduce maintenance costs.
Its techniques and processes provide hard, durable, self-lubricating and corrosion, scratch, and wear-resistant tools and components. Ceramic coatings protect against burn, corrosion, destructive abrasion and adhesive wear, ensuring a longer lifetime of tool parts, which means fewer tool replacement and lower production costs.
Coatings solve critical challenges associated with friction, including the need for dry lubrication of moveable parts. Low friction properties reduce the tendency to sticking and material pick up from the counter surface, substantially reducing the downtime required for cleaning.
Furthermore, slip and non-stick properties reduce deposits of plastic and improve de-moulding, easing the cleaning, shortening the cycle times and increasing product quality.
Low-temperature processes for PVD coatings
At CemeCon Scandinavia, the company processes a wide variety of tool parts with PVD, including polished, etched and eroded surfaces, mould cavities and moving parts, cores, inserts, sliders, ejecting rings, hot runners, nozzles and needles.
Unique low-temperature processes enable clients to apply the coatings to most metals – even temperature-sensitive substrates, without the risk of deformation, and coatings are so thin (standard layer thickness of 1µm -3µm) that they are suitable for even high-tolerance parts.
Surface treatment expertise
CemeCon Scandinavia’s expert knowledge includes low-temperature coating, coating of eroded and polished surfaces, coatings in combination with small tolerances and optimal preparation of tools before coating.
The company has a comprehensive approach to surface treatment, not only considering the coating but also a combination of pre-treatment and post-treatment to obtain the best result.
In addition to its PVD-machines, CemeCon Scandinavia has de-coating facilities, advanced automated cleaning plants, blasting and polishing equipment, as well as tribological test and control facilities.
PVD sputtering capabilities
At CemeCon Scandinavia, the company uses PVD unbalanced magnetron sputtering.
PVD unbalanced magnetron sputtering is a coating technique where gas in a vacuum chamber is ionised (plasma) and is used to move (‘sputter’) metal on tools, then deposited as a surface coating with unique properties such as low friction, wear-resistance, high hardness, self-lubrication properties, and good slip properties.
Layer thickness is typically 1μm–30μm, while the process temperature varies from 100°C to 500°C. The technique provides careful control over the thickness and surface chemical composition and provides a very smooth surface free of defects and no corner build-up, which is preferable to other coating techniques.
CemeCon Scandinavia’s broad service programme and specialised knowledge enable it to solve tasks in various industries such as pharmaceutical, food and plastic.
Close cooperation with its research and development (R&D) department ensures that CemeCon Scandinavia’s sales team is up-to-date on the latest technological developments.
