Filament Winding

The endless glass or carbon fibres are mechanically impregnated in a resin bath and placed on a rotating mandrel by CNC-controlled machines. The completely automated manufacturing process guarantees absolute reproducibility and the highest quality of series components. In addition, the winding technology, also known as filament winding, is extremely economic thanks to low contract manufacturing costs and minimal waste of expensive materials as with conventional fibre composite processes.

Guaranteed high economic efficiency
Component solutions are manufactured with absolute precision and in high quantities, thanks to optimally automated and customisable production. It is primarily suitable for the production of rotationally symmetrical components such as pipes, shafts, beams or containers.

Outstanding strength with winding technology:

• Perfectly defined fiber placement
• Optimal mechanical properties
• Ideal fiber content
• Low pore content
• Reduced weight
• Lower inertia
• High rigidity
• Very good vibration damping
• Very low thermal expansion

Compared to CFRP components made of woven fabrics, wound components weigh 20% less and achieve the same mechanical properties. The method is characterised by its high accuracy and good reproducibility. The processes can be largely automated and produce highly economical reproducible components - even in small series.

Applications in the following segments:

E-mobility: rotor strip tubes, canned tubes
Automotive: compression struts, test bench actuators, tension straps
Aviation: supports, struts, camera carriers
Mechanical engineering: tool extensions, laser guide tubes, rollers, pressure tank drum robotics Actuator tubes
Water Treatment: Pressure pipes, filter bodies

Know-how and resources optimally combined:

• Multi-spindle CNC winding machines, each with four freely programmable axis
• Maximum winding length up to six meters
• Largest diameter 600mm
• Maximum weight per component 1,500kg
• CNC process software and winding simulation with "COMPOSICAD"
• Computer controlled and automated curing ovens
  
  

Winding machine

A winding machine consists of a turning device for the tool mandrel, thread guide and thread storage and a resin bath that moves back and forth along the axis of rotation. With a revolutionary winding machine from the German world market leader "Roth Industrie", CONNOVA offers a stable and fail-safe component supply, especially for large series production of 10,000-100,000 components per year. Due to the new process data monitoring system, an excellent process capability level is achieved so that new markets & applications can be addressed, which could not be developed by means of existing technology.
