Efficient lightweight solutions, maximum performance and new possibilities for industry and technology
Pultrusion – the continuous extrusion process
Pultrusion enables the efficient and automated production of fiber-reinforced profiles with constant cross-sections. The combination of high-performance fibers and specially matched resin systems produces components with outstanding mechanical, chemical and physical properties. CG TEC produces both standard products and individual custom-made products on nine state-of-the-art pultrusion systems, guaranteeing maximum precision and reproducibility. One of these systems is available for customized customer projects, particularly for development and research purposes.
Advantages of pultruded products
Pultruded profiles offer decisive advantages in practical applications: With up to 80% less weight than comparable steel components and higher specific strength at the same time, they enable significant weight savings in constructions. The excellent corrosion resistance to acids, alkalis and salt water makes the profiles ideal for aggressive environments in which conventional materials would fail. Thanks to their minimal thermal expansion, they guarantee maximum dimensional stability even with temperature fluctuations – a decisive advantage for precision applications.
The excellent dielectric properties predestine the products for applications in the electrical sector where electrical insulation is required. Particularly noteworthy is the exceptional fatigue strength: pultruded profiles retain their mechanical properties even after millions of load cycles.
Variety of applications and customer benefits
In the field of pultrusion technology, CG TEC’s product range includes both round rods and flat rods in various dimensions made from carbon, glass or basalt fibers. These products are used in numerous industries:
- Medical technology: CG TEC is the market leader in the field of external carbon fixators
- Automation and robotics: lightweight components for highly dynamic applications, such as components for drones
- Measuring technology: Precision rods for the highest accuracy requirements
- Sport and leisure: unbreakable, lightweight and age-resistant components, such as the Flexi-Bar or the innovative “Fiber Divider” room divider
- Construction industry: Innovative reinforcing bars made from high-performance fibers for sustainable concrete structures
Customers benefit from high cost efficiency through automated production processes, increased performance through optimized material compositions and sustainability through reduced material usage, low energy consumption and recyclability. Close cooperation with customers enables CG TEC to analyze individual requirements and develop tailor-made solutions that offer real added value.
Technological challenges and solutions
Pultrusion is traditionally designed for profiles with a constant cross-section. CG TEC meets this challenge with specially developed processes that also enable more complex geometries. The targeted use of special reinforcing materials and optimized fibre orientations also achieves outstanding mechanical properties. Continuous process optimization – especially in resin absorption and curing – guarantees consistently high product quality and minimizes air inclusions.
Future prospects and innovative strength
The global demand for pultrusion products is growing steadily. CG TEC is continuously investing in research and development in order to open up new fields of application and further optimize production processes. The company sees great potential, particularly in the area of sustainable building materials and renewable raw materials such as flax and hemp fibers. With its many years of experience, innovative strength and customer focus, CG TEC is ideally positioned to further expand its technological leadership and open up new markets.
