How and where we produce
Where we produce
CAST helmets are entirely produced in Italy by companies belonging to the BELL Safety group, leader in the production of military and professional helmets by specializedpersonnel with long experience.
The materials we use
For the shells, neglecting the characteristics of helmets in Plastics Resin, generally suitable for Jet or cheap helmets, we evaluate the differences between the Fibers used to obtain the best performing helmets.
The helmets commonly called "in Fiber" are produced by impregnating with a "binder" hardener resin a fiber that acts as a supporting structure and determines the strength and characteristics of the helmet.
The normal glass fiber is the most economical and less resistant supporting component as well as heavier, the weight / strength ratio is very disadvantageous.
A cheap fiber helmet check it out with a "high" weight
The Multiaxial fibers possibly reinforced with Carbon or Aramidic greatly increase this ratio for which light and resistant helmets are obtained.
The maximum of this weight / strength ratio is obtained by using carbon fibers impregnated with epoxy resins and is currently the best high-tech material that the industry is able to produce in appreciable quantities.
A carbon fiber is a long and thin wire largely composed of carbon atoms, several thousand carbon fibers are intertwined together to form a fabric with a very high tensile strength. To give an idea, the tensile modulus or the resistance that can withstand without breaking is more than 140 M.psi for more resistant and quality fibers.
To make a comparison, steel has a modulus strength of about 29 M.psi, so the best carbon fiber is about five times stronger than steel (and lighter).
The carbon fiber fabric obtained from thin carbon filaments arranged according to the classic warp and weft scheme, is impregnated with epoxy resins to obtain helmets with exceptional strength and limited weight.
The production takes place by hot molding after exact stratification of the fabrics and impregnation of the resin or by autoclaving.
Historically, the best production of carbon fiber products is recognized as "Made in Italy" or "Made in England" areas of great development in this sector (F1 auto experience) and where it resides personnel with long experience
This is due to the type of carbon fiber used and the operator's experience
