CORMASTER® is SCHÜTZ’s High-performance Composite Material
SCHÜTZ has announced a significant technological leap forward in its COMPOSITES division, underlining its commitment to serial precision and the latest advancements in lightweight construction. Through systematic and targeted investments in new equipment and state-of-the-art control technology, the company is continuously refining its production processes to ensure that every stage of manufacturing consistently meets the highest quality standards. As outlined in the December 2025 issue of SCHÜTZ NEWS, these measures further strengthen the long-term reliability, supply security and performance of its high-tech lightweight materials.
At the heart of this progress is CORMASTER®, SCHÜTZ’s high-performance composite material, which combines exceptional strength with outstanding resistance properties. Thanks to these characteristics, CORMASTER® is used worldwide in highly demanding applications, including the aerospace industry as well as vehicle and boat construction. The material forms the core of sophisticated sandwich panels that are manufactured using a thermal pressing process. In this process, the CORMASTER® honeycomb core is combined with one or more layers of prepreg, consisting of pre-impregnated glass or carbon fibre textiles, and consolidated in multi-stage presses. These technologically advanced production steps demand precise process control and maximum temperature homogeneity, requirements that have guided SCHÜTZ’s most recent investments.
A central component of the expansion strategy is the installation of an additional sandwich panel press, scheduled to go into operation at the beginning of 2026. With this new press, SCHÜTZ will increase its production capacity by approximately 40 percent. Designed identically to the existing system, the new press introduces valuable redundancy into the production environment. This not only enhances operational reliability but also enables flexible production planning, even during periods of high-capacity utilization. By creating parallel capabilities, SCHÜTZ is reinforcing its ability to guarantee dependable delivery performance for customers operating in safety-critical and time-sensitive industries.
Further strengthening its production infrastructure, SCHÜTZ has installed a new CNC cutter within the clean room facility at its Siershahn plant. This cutter is dedicated to high-precision prepreg cutting and operates entirely under controlled clean room conditions. By ensuring that processing takes place exclusively within this controlled environment, the company effectively prevents contamination and maintains a consistently high level of product quality. The integration of the cutter directly into the clean room also shortens transport distances and eliminates the need to move cut materials outside the protected area. This significantly reduces the risk of contamination, increases process reliability and allows for faster response times to customer requirements.
In parallel, an existing CNC cutter previously used for honeycomb processing in Siershahn has been relocated to Selters. At this site, SCHÜTZ will now produce customer-specific components based on individual drawings in a “built to print” approach. The relocation enables flexible and precise manufacturing with shorter internal transport routes. In addition to improving responsiveness and efficiency, these streamlined logistics contribute to a reduction in CO₂ emissions. Together, these measures underscore SCHÜTZ’s commitment not only to technical excellence but also to sustainable production practices.
The Siershahn facility has also undergone a comprehensive upgrade of its existing sandwich panel press. The system has been equipped with a state-of-the-art control platform featuring a high degree of automation. This modernized control system processes and evaluates production data with even greater precision, allowing for more effective diagnostics, faster maintenance interventions and continuous system optimization. Improved spare parts availability further enhances operational dependability, providing a substantial boost to supply security for customers.
Temperature control, a critical factor in the thermal processing of composite materials, has been enhanced through the integration of additional measuring points within the system. These sensors enable comprehensive monitoring of temperature homogeneity and allow precise recording and documentation of temperature curves throughout the process. As a result, SCHÜTZ fully complies with the stringent requirements of the AMS 2750 standard governing heat treatment processes in the aerospace industry. This compliance ensures that customers can rely on consistently high product quality, even in applications where material performance and safety are paramount.
All sandwich panels continue to be manufactured under strict clean room conditions, guaranteeing a controlled production environment and effectively eliminating contamination risks. With its latest investments in equipment, automation, clean room integration and capacity expansion, SCHÜTZ is laying the foundation for sustained growth in its COMPOSITES business segment. The company is positioning itself to continue delivering component manufacturing at the highest technical level while ensuring uncompromising quality, availability and supply reliability for customers worldwide.
Through these forward-looking initiatives, SCHÜTZ reaffirms its role as a technology leader in lightweight construction and advanced composite manufacturing. By combining serial precision with cutting-edge process control and strategic capacity expansion, the company is setting new benchmarks for performance, reliability and customer-focused innovation in the global composites market.
