About us: Partner for mechanical engineering and automation

In 1921, Amandus Keller laid the foundation, initially with film development equipment that was supplied to film and sound studios around the globe. Today, as Keller Feinwerktechnik GmbH, we primarily specialize in custom machine construction. In Elmshorn, we work closely together in two facilities: production and technology center. Here, extensive practical experience meets the possibilities of modern digital development, and this combination is crucial to us.

Our range of services is quite broad: from the production of CNC precision parts on machines like Mori Seiki or DMG/Mori to complete custom machines and automated turnkey systems. Robotics, conveyor technology, and industry-specific solutions are also part of our portfolio. Whether automotive, medical technology, packaging, or textiles. And we support projects not just up to the prototype stage, but all the way to completion: from the initial concept to commissioning, when it really matters.

What drives us is a very clear ambition: precision, innovation, and quality, and we've upheld these principles for over 100 years. For us, this also includes sustainable processes, energy-efficient facilities, and Industry 4.0 concepts where AI isn't just a buzzword, but meaningfully integrated. Ultimately, production should run smoothly, remain transparent, and be able to scale with the company. Customer proximity means short communication channels, rapid response times, high flexibility, and reliable service. We're rooted here locally, but our vision extends far beyond the local area.

As a certified company, we operate according to recognized ISO standards, ensure CE conformity, and consistently document quality at every step. With a focus on automation, precision manufacturing, and the efficient use of materials and energy, we develop solutions that not only work today but will also be relevant tomorrow.

Our main facility is located at
Fritz-Straßmann-Straße 2, 25337 Elmshorn.

At our Technology Center, we integrate development, assembly, and testing into a seamless process. Here, we assemble custom machines precisely to meet specific customer requirements and test their functionality under real-world conditions. At the same time, we conduct feasibility studies to evaluate technical concepts at an early stage, reduce risks, and establish a solid foundation for decision-making. This results in solutions that are not only innovative but also economically viable and reliably implementable. Our customers benefit from short decision-making processes, high flexibility, and a clear focus on practical applicability.
