WOLL.AUTOMATION
Your partner for automation solutions
Automation is more than technology. It is a decisive factor for product quality, time-to-market, and cost-effectiveness. We develop customized automation solutions for companies with complex production processes.
Together with you, we analyze product, process, and technical, economic, and regulatory requirements in detail. On this basis, we develop tailored turnkey solutions – end-to-end: from design, through our own manufacturing, programming, to commissioning and beyond. Always with the commitment to automate processes so that they produce economically from day one.
Our strength lies in our ability to combine mechanical and process engineering. This enables us to automate critical processes and implement automation systems that consistently deliver safe and efficient results, even under high demand. Each system is unique. They are designed based on your specific process requirements.
As an experienced automation partner, we support our customers throughout the entire system lifecycle – worldwide. We offer direct communication, high reliability and service beyond the warranty. The result is automation solutions that streamline processes, cut costs and generate long-term competitive advantages.
For industrial automation that works. Today and tomorrow.
WOLL.MANUFACTURING
Precise metal solutions for every project size
WOLL.Manufacturing stands for precise metal processing with a high degree of vertical integration. We manufacture demanding components and assemblies in sheet metal processing, CNC machining, welding technology, and tube and profile processing. From single parts to series production and complex large-scale projects, we realize solutions that are technically convincing and economically viable.
Our particular strength lies in stable, controlled manufacturing processes. Modern machines, clear procedures, and experienced specialists ensure high process reliability, reproducible quality, and on-time delivery. Even with tight schedules and high demands. Thanks to scalable capacities and clear structures, our customers can plan reliably. Technically precise, economically sensible, and at the quality level expected by demanding industries.
WOLL.SEMICON
Process technology for semiconductor manufacturing
Within the WOLL.Group, WOLL.Semicon represents cutting-edge technology in semiconductor and microtechnology. As a brand of M-O-T Mikro- und Oberflächentechnik GmbH, we have been contributing in-depth experience to the development and manufacture of production systems for demanding semiconductor processes for over 25 years.
Our particular strength lies in our in-depth process understanding of wet-chemical manufacturing. This expertise forms the basis for customized equipment systems that reliably cover all front-end and back-end processes in semiconductor production. The systems are modular in design and flexibly scalable, enabling efficient integration into large-scale production, small-batch series, pilot lines, and laboratory environments.
In addition to complete system solutions, we also supply process-critical components and specially coordinated chemicals that are optimally matched to each other and ensure maximum precision and stable processes during operation.
Through excellent process control, high material compatibility and consistently well-conceived, environmentally sound system concepts, WOLL.Semicon sets standards in the semiconductor industry. Our technologies combine efficiency, reliability and sustainability and meet even the strictest requirements for quality and environmental standards.
This creates solutions that not only convince today, but also create long-term technological reliability and competitive advantages.

We are happy to assist you.
