The manufacturing processes in medical engineering must meet the most demanding standards. Surfaces must not only be clean but perfectly flawless and/or sterile. All our systems are equipped with a USB and LAN connection to ensure traceability of pretreatment process by way of printed-out process records. Since we are certified to DIN EN 13485, we meet all the specified requirements in the quality management system that apply when a company must submit proof of its ability to deliver medicinal devices and the respective services.

We also offer this process as surface treatment services provided on our premises. Several plasma systems as well as skilled and experienced staff are at your disposal. Our class 8 clean-room is certified to DIN ISO 14644. Thus, we can ensure optimum surface quality of your components and parts.

Materials cleaning

Plasma technology offers solutions for any type of contamination, for any substrate and any post-treatment. In the process, molecular contamination residues are decomposed as well.

Activation of materials

Good wettability is a prerequisite for the adhesion of binding partners in painting, gluing, printing or bonding.

Etching materials

Plasma technology allows for anisotropic and isotropic etching. Isotropic etching is done by chemical etching and anisotropic etching by physical etching.

Coating of materials

With low-pressure plasmas, components can be tempered with various coats. This is done by supplying gaseous and liquid starting substances into the vacuum chamber.

Frequent applications of plasma in medical engineering

Medical engineering is developing constantly, and implants are one of the fields where much progress is made. An implant is a piece of artificial material implanted in the patient’s body to stay there permanently or at least for a long period of time. Despite the continuous advances of the technology, some problems remain. In many cases, for example, the patient’s body reacts to the implant with an infection, or it takes very long for the body to properly integrate the implant. Made of artificial substances, it is not bio-compatible; the patient’s body often perceives the implant as foreign matter and will reject it in the worst case. The so-called stents used to hold open blood vessels or hollow organs usually consist of a cylindrical wire-mesh structure made of metal or synthetic fibres. One of the potential problems is the high friction coefficient which makes it difficult to introduce the stent into a vessel.

Thanks to our plasma treatment, implants will be integrated into the body faster and more firmly while the risk of infection is reduced. Joint and dental implants are made truly bio-compatible by plasma treatment. Stents are coated by means of plasma polymerisation of HMDSO, which creates surfaces with a significantly reduced friction coefficient.
