CNC Turning


We specialize in the manufacturing of complex turned parts made from titanium, stainless steel and nonferrous metals and plastics, primarily for use in medical technology.​

Wire Erosion


All conventional conductive materials can be processed, including PCD and CVD.



In addition to conventional tools, we also specialize in the grinding of surgical twist drill bits for dental technology, rotors for cardiology, bone screws and tips for laboratory technology.

CNC Milling


Complex production with 5-axis and 3D machining of components made of titanium, stainless steel and nonferrous metals, aluminum and plastics, primarily for use in medical technology.

Laser Marking


Various materials such as steel, titanium, brass, aluminum and even diamond can be processed.
QR codes, GS1 data matrices as well as barcodes can also be applied.



The SDI GmbH team have many years of experience in assembling and testing a wide variety of products. Test protocols can be generated, if required.

Consultancy | Design | Prototypes

Thanks to our knowhow, we can help you to optimize the product and solve problems.

Our services:


  • Design and calculation

  • Photorealistic product visualization

  • Instrument development for ophthalmology




The QM system 9001:2015 / ISO 13485:2016 ensures that processes and procedures are adhered to so that process reliability is guaranteed.

Thanks to our production planning system, an electronic production order can be generated for each order. This features every partial stage of processing. They are also labelled with a barcode. This guarantees the traceability of semi-finished and finished products.
