Consultation Advanced ceramics Independent, impartial and individual The ideal material in medical technology

Every project is unique This is why a close analysis of the requirements and the field of application come first. Selecting the perfect material is crucial to the success of a project. With our many years of experience and our independence from raw material suppliers, we offer our customers impartial advice when it comes to selecting the best material. We also sup- port them in the development of efficient designs for large-scale production and in hard material engineering. Thanks to our systematic project management, we are able to successfully run large customer projects.

Our engineering makes it possible

Manufacturing components in very small 3 mm dimensions is one of our greatest strengths. In order to machine superhard materials with the highest precision, we develop our own special manufacturing systems, tools and equipment. Our R & D engineers have many years of experience and are familiar with the challenges. 2 mm
