MERTEN precision engineering
MERTEN machine engineering

The Merten Group is a stable, family-owned company that operates in three business areas: precision engineering, mechanical engineering and Postpress. We have been successful in the market for 100 years and have always been owner-managed - today already in the 5th generation.

MERTEN-Präzisionstechnik manufactures complex and high-precision components - primarily as a reliable contract manufacturer, but also for its sister companies MERTEN Maschinenbau and IN-LOG | GÄMMERLER. We process all orders on state-of-the-art CNC 5-axis milling/machining centers as well as CNC lathes and grinding machines. Common to all our systems is a high degree of automation, resulting in impressive productivity. Our international customers value us as a high-quality supplier with extensive experience in the fields of mechanical engineering, the rail vehicle industry and precision engineering (e.g. aerospace, microscopy, orthopaedics).

Precision engineering
MERTEN Präzisionstechnik

We have decades of experience in plant engineering and parts manufacturing. This qualifies us as a reliable partner for the realization of your projects. Machine development from prototype to series machine, electrical design, control cabinet construction and PLC programming are just as much a part of our services as assembly, commissioning and on-site training. A particular strength of MERTEN Maschinenbau is automation, especially in the areas of conveying, stacking and robotics.

Mechanical Engineering
The best of both worlds: IN-LOG | GÄMMERLER is a leading post press supplier, implementing intelligent and reliable solutions for commercial, book and newspaper printing.
Our solutions range from single machines to complete systems and include new and refurbished equipment, upgrades, machine relocations and reconfigurations. With the largest installed machine base in the world and a clear commitment to the printing industry, we are the first choice for your Postpress projects.
As part of the Merten Group, we have the technical knowledge, experience and financial stability to deliver these projects reliably and successfully over the long term.

For more than 40 years Gämmerler has been shaping the world of Postpress. The FS 260 conveyor system, the RS 114/134/164 trimming lines, the KL 540/560 compensating stackers, the SH 700 log stacker and the PR 460/480 robots are used successfully by a wide range of printers worldwide. In 2021, the Merten Group took over Gämmerler with a clear goal - to provide professional service & support for the many Gämmerler installations worldwide!

IN-LOG was founded in 2001 as the Postpress division of the Merten Group. In recent years, the focus has been on Europe, where In-Log has installed fully automated and highly efficient Postpress systems behind the fastest and widest presses, up to the latest 96-page web presses. In-Log also regularly supplies machines and components to various other manufacturers, including Gämmerler.
