Ablation
Laser systems allow high-precision selective material ablation of metals, ceramics, or polymers. The ablation process is characterized by short, highly energetic laser pulses. Surfaces can be furnished with structures in the micron range. The precise control of this process allows microstructures smaller than 15 µ as well as the ablation of entire surface layers.

Parylene Deposition
 |
Parylene-deposition equipment features a compact size that handles small volumes. Its small size together with a reliable construction makes the C-30-S suitable for laboratory use as well as for mass production. Parylene vacuum surface treatment provides an inert, biocompatible barrier to moisture and chemicals for medical components such as stents, tubes, needles, and pressure sensors. The company’s equipment are all CE certified.
Comelec
Plasma Process
 |
A low-pressure plasma process cleans and activates the surfaces of polymers. The plasma treatment is designed to optimize the polymer surface to improve the wettability of products such as blood tests and filters, dialysis filters and syringes, catheters for gluing processes, and implantables. The gas plasma can clean any plastic surface or prepare it for adhesive bonding.
Europlasma
Corona Treatment System
 |
A compact, self-contained floor-model corona treating system can treat most 3-D plastic parts. Any nonmetallic item that can fit through FlexiDyne’s 6-in. wide Ą up to 2-in. high opening can receive uniform corona treatment on all exposed areas.

Surface Modification
 |
A surface-modification technology platform improves lubricity, haemocompatibility, infection resistance, and tissue integration. PhotoLink technology adds properties to a surface without changing the bulk characteristics of the material. PhotoLink reagents are first dissolved in water and the solution is then applied to any hydrocarbon-containing substrate. Exposure to UV light activates a chemical reaction that produces a covalent bond between the coating and the device surface.
