Aluminium oxide coating with microcrystalline barrier
extensive corrosion.
■ MICRALOX Lumina: Whether natural or dyed one of nine vivid colours, Lumina achieves 16 times the resistance in a hot alkaline strip test compared with Type II decorate anodising. It provides a perfect balance of breakthrough chemical resistance and design flexibility for medical device applications. With MICRALOX on the market for use on reusable cases, trays, tools, and components, the impact on the medical industry has been transformational.

Additive-free clear- to-clear welding
MICRALOX helps to revolutionise aluminium anodising.
Precision Coating offers a variety of innovative anodic coating solutions for medical equipment. MICRALOX, a speciality anodic coating, produces long life cycles for critical medical device instrument surfaces. Not only does it achieve extraordinary chemical and corrosion resistance, but it maintains its performance in high cleaning and sterilisation environments. It’s an excellent alternative to stainless steel, plastic, and other materials. The MICRALOX family includes: ■ MICRALOX Ultra:
When maximum performance for strong alkaline cleaning is critical to quality, Ultra provides 50 times the chemical resistance compared with decorative Type II anodising. These coated parts can also withstand other aggressive environments that would otherwise strip conventional anodic coatings and subject the parts to
is due to the vibration overtones of molecular bonds. The exact wavelength and strength of the absorption bands depend on the polymer’s type of atoms and bonds. Only completely fluorinated polymers like PTFE or PFA show no absorption at this wavelength region. A good example is the tubing for artificial respiration (tracheostomy) from soft PVC. An inflatable balloon must be welded leak-tight outside the main tube. There is a small channel in the main tube wall to inflate the balloon, which needs to stay open at the welding position and not collapse. The tube assembly is rotated in the focused laser beam absorbing part of it in the balloon wall and the upper layer of the tube melting both together. With the laser power in the appropriate process window, the small channel in the tube wall is not melted and stays open.
The Turnkey S uses a long-wavelength laser to weld a clear balloon to a breathing tube.
The traditional wavelengths for laser welding of plastics are 800–1,100nm, at which all polymers are transparent for the laser. To obtain absorption of the laser beam and heating for welding, a special dye or pigment must be added to the polymer. For medical applications, this additional colorant may require other considerations because it needs the requalification of the plastics with a new additive. A solution is to move from the standard wavelengths to longer ones. At 1,700–2,000nm, most polymers absorb slightly without an absorber. The weak absorption

All ProByLas’ machine platforms can now be equipped with a long-wavelength laser from Modula integration components to ready-to-use Turnkey S and M. In the contour process, the beam is focused on a spot, and a multi- axis servo aims the beam along a programmed trajectory. Compared with the traditional wavelengths the process is slower as a deeper melt zone is created with more energy necessary.

Superior Felt & Filtration offers a range of materials that are highly efficient against sub- micron particles. Many harmful airborne and suspended particles, including viral and bacterial particles, are less than 1µm in size. The ability for a filtration system to effectively filter these sub-micron particles is critical to the well-being of humans and the protection of sensitive equipment. Its Technostat family of tribo-charged needle-punched products are unique in providing a high level of sub-micron
