Saver S.p.A. is the global leader of production of filament winding tubes (FWT) of glass, polyester and aramidic fibers for electrical and industrial applications.
The company has resources for developing, producing and selling standard and tailor-made FWT.
Our technicians and sales force have many years of experience in composite materials, which allows for efficient collaboration with customers as we find the most advantageous solutions, in keeping with specific customer requests.
Some examples of application of our FWT are:
All following insulating fibers have been used through these years in the production of Saver:
The design of the filament wound tube can be customized to obtain the mechanical values requested by the customer considering the specific application.
Epoxy resins with Tg > 120÷130°C
Special resins with Tg > 300°C for special heavy applications and special requirements.
The design of the tube is extremely flexible. The winding angle can be chosen and changed even inside the same product for different layers of the winding process, in order to give the composite materials specific mechanical characteristic requested by the customer depending on the final application.
In this sense, the winding angle will determine the orientation of the impregnated fibers of the composite material depending on the mechanical properties to be enhanced compared to the others.
Our experience enables us to propose successful solutions, supported by our test reports on prototypes and samples. Moreover we can choose different resin systems considering the exercise temperature of the product and / or specific applications. For some particular applications we are also able to produce conical composite materials. All our tubes can be machined and different solutions can be decided with the customer (considering the application) for the finishing of the outer surface (taping, varnishing, machining etc…).
