Cendres+Métaux - Your Specialist for Implantable Micromechanical Components

Cendres+Métaux specialises in the production of implantable, micromechanical components or systems with complex geometries made from precious metal or titanium alloys. We also offer non-metallic implant solutions with machined or moulded components made from PEKK, the newest generation in high-performance polymers.


Cendres+Métaux is a mid-sized company employing around 430 people worldwide. With more than 125 years of experience, the company combines traditional values with innovative solutions in order to provide its customers with individual concepts bringing true added-value to their business.

Cendres+Métaux is accredited and certified ISO 13'485 / 9001 / 14001, as well as FDA registered.

From engineering to packaging

If you wish to launch a new medical device, but are missing a reliable source for your micromechanical components, Cendres+Métaux's competent and experienced engineering and sales teams are here to help.

Our team can assist you with any technical questions, as well as conduct a feasibility analysis, before ensuring an ideal manufacturing process for serial production.

Cendres+Métaux has a wide range of standard packaging options available, including trays, deep-well trays, tubes, capsules, blisters and peel pouches, nearly all of which can be adapted to customer requirements. If your vision of the perfect packaging is not amongst our standard solutions then special packaging enquiries are always welcome.

Our skilled engineers will present you with different options, and together you can determine the best possible packaging option for your device. What's more, they will also help you to establish a realistic project schedule, as well as supervise your project from the idea, through to the successful market launch.


From inspection to certificate of conformity

If required, this process can also include the establishment of the relevant legal documentation, in which case the quality management and regulatory teams will advise you in this matter. Quality control plays an essential role at Cendres+Métaux, with dimensions, materials, surface finishes and packaging continuously recorded and monitored, to ensure a consistently high-level of quality.

Cleanliness is also a top priority with Cendres+Métaux. Our in-house microbiologist is ready to help with any concerns surrounding the production environment your devices are produced in. We constantly monitor production environments, as well as validated cleaning processes, to ensure a safe and traceable manufacturing operation.

From casting to micromachining

Cendres+Métaux has more than 125 years' experience in refining, casting and processing precious metals. To ensure that the highest quality requirements for homogeneous alloys are met, we operate our own accredited metallurgical and analytical laboratories according to ISO/IEC 17025. All our casts are first analysed, documented and approved, before they can be further processed into semi-finished products.

Due to our long refining and casting tradition, biocompatible precious metal fine wires, strips, sheets and bars naturally belong to our wide range of customised products. Our wires offer an excellent radiopacity, are biocompatible and perfectly applicable for long-term implantable uses. They exhibit a completely even surface and maintain the tightest tolerances. If you are interested in high-quality, fully biocompatible, homogenous, radiopaque, precious metal fine wires, bars or strips, your search stops here.

From development to analysis

Our internal analytical and materials testing laboratories characterise and test new materials, verify the quality of alloys, as well as investigate complaints. The most important procedures have been accredited by the Swiss Accreditation Service in accordance with ISO/IEC 17025, and are registered under STS 174. In addition, the analytical laboratory is regularly inspected by the Swiss Precious Metals Control authorities.

Our accreditation highlights that our laboratories make independent testing decisions, employ competent staff and work with validated methods. Moreover, our laboratories are able to trace the tested merchandise back to the test results.

Therefore, we assure the application of medical device and precious metal legislations which help to guarantee the conformity of our products.

From tradition to modernity

Cendres+Métaux recently introduced the high-performance polymer Pekkton®, a material based on OPM's OXPEKK®-IG, to the dental world. Pekkton® will allow its customers to break new ground in dentistry product development. Over the past decades, our thermoset and thermoplastic polymers have been widely employed in the dental market.

The material most often used is called PEEK, a fibre-reinforced thermoplastic (polyetheretherketones). But because of its crystalline structure, PEEK's performance is limited, and the complex manufacturing process needs fingertip accuracy.

However, Pekkton® is based on another member of the polyaryletherketone family, polyetherketoneketone (PEKK), and has been specifically developed for dental applications. Unlike PEEK, the Pekkton® line offers crystalline as well as amorphous structures, which means a wider range of products can be offered.

Furthermore, the material has a slow rate of crystallisation, making it possible to obtain tight tolerances without expensive and time-consuming post-treatments. With its greater processing flexibility, the Pekkton® line will contribute to the development of successful products that provide both structural and aesthetic satisfaction.

For implantable medical devices outside the mouth (short and long-term applications), Cendres+Métaux offers a high-performance polymer named OXPEKK-IG. Similar to Pekkton®, OXPEKK-IG200 offers a high processability, including optimal flow and crystallisation kinetics, as well as considerable mechanical properties (about 50% greater compressive ultimate strength than PEEK, most other properties about 10%-15% greater than PEEK).

From creation to visualisation

Cendres+Métaux can even support you with your marketing documentation. For example, if you would like to post an animated video on your website showing your implant in action, then all you would need to do is bring your 3D files and instructions, and Cendres+Métaux can help. Equipped with the latest 3D animation software, Cendres+Métaux's in-house specialists can create fantastic visualisations of your product.
