Manufacturing, Our Core

Production of
Surgical Instruments

In the Manufactory

High Tech and Know-how

In the spirit of our company name, our in-house manufactory provides almost every step from conception to finished surgical instrument in one location. Any off-site production steps are executed to our guidelines by qualified suppliers from the Tuttlingen area, situated at the heart of the world’s center of medical engineering, and the neighboring regions.

“Made in Germany” is not just a saying at Raimund Wenzler but a reliable seal of quality.

Since 1932, the Raimund Wenzler manufactory has developed and produced premium surgical instruments. Our production is based on the traditionally honed craft of surgical mechanics. This artisanal basis is effectively supported by the application of the most current production technologies, resulting in surgical instruments of highest precision, certified quality, as well as perfected handling. Even with the most complex procedures, we ensure that you – and your patients – can rely on our instruments completely.

Experience our manufacturing spectrum for yourself:


The foundation of our premium instruments’ precision starts with component production. Our machining process with a geometrically defined cutting edge forms the basis for the finished surgical instruments.

Our CNC-experts are trained to operate the most current CAM-/CAD-software and CNC-machines. Their experience and special knowledge greatly impact the precision of our finished instruments. Our roster of CNC-machinery is tailored perfectly to the production of surgical instruments. In combination with long-term and flexible production planning we have set the optimal course for a timely production.

Hardening / Heat treatment

By heat treating our surgical instruments, they attain the optimal properties for their final usage. During hardening, the workpiece achieves the desired stability through the transformation of the material composition. To ensure these processes, our validated hardening unit is monitored regularly. After tempering, the material is at its definitive hardness while the tensions generated through hardening are reduced.

WIG- and laser welding

Both WIG- and laser welding are conducted at our manufactory. WIG-welding encompasses the use of protective gas and tungsten electrodes. At Raimund Wenzler, we use additional material to ensure quality of our welding seams.

The process of laser welding is distinguished by the supply of energy through a laser beam. This allows is to precisely weld even the smallest seams.

Grinding / Polishing

The machining process with a geometrically defined cutting edge removes any remaining burr after milling. Our belt grinder prepares the foundation for your surgical instrument’s ideal surface. We ensure that the finished surgical instrument is haptically pleasant and provides ergonomic handling.

The subsequent polishing process then creates the prerequisites for corrosion resistance, sterility, cleanliness during lavation.

Rapid Prototyping / 3D-Printing

Using our in-house 3D-printer, we are able to provide you with a prototype of your functional model. 3D-models can be printed from synthetic material or steel. These prototypes offer a dynamic impression of the finished surgical instrument. Therefore, possible improvements become visible and facilitate the joint development of product between you, the client, and RW as your contract manufacturer.

Surface / Coating

During coating, additional material is applied to the surface of the surgical instrument.

Our Ebony (black TiAIN) coating: An elegant black coating that protects from reflection. The Ebony coating provides a striking visual effect as well as definitive advantages in application: protection from distracting reflections which facilitate use without bothering glares. In the long term, the surface is in no way impaired by aggressive reprocessing .

Aside from our Ebony coating, other custom coating treatments are available by request.

3D-Coordinate measuring

Our 3D-coordinate measuring device is an essential component of our quality control. This efficient measuring technology is used in the inspection of form and position tolerances. It can be navigated exactly and is this highly precise. The 3D-coordinate measuring device provides a consistently high and steady measuring quality, offering a strong comparability in readings. Therefore, possible inaccuracies and inconsistencies are quickly detected and eradicated.

Laser marking

During laser marking, the surface of the surgical instrument is directly penetrated by the laser beam. By engraving the product, traceability according to Unique Device Identification is provided for each surgical instrument. In agreement with our partners, an individual product identification with numerical codes is created in accordance with current standard specifications.
