An eye surgeon, neurosurgeon, or other medical specialist often works with a precision down to the nearest half millimeter. The surgical tool is then many times smaller. Those tools should function smoothly and be pleasant to work with. In addition, that instrument must provide good guarantees of success in medical intervention.

To measure is to know and seeing is believing. In other words, with a prototype of the design, we verify that the theory will work in practice. When prototyping for precision mechanical parts, we go beyond construction alone. When necessary, we even design and build our own tools to develop and create the prototype. It goes without saying that we will work with you at the same time to investigate whether the design can be mass produced effectively and at an acceptable cost. Want to know how that works? Let’s get acquainted.
