Fundamental technology for
increasing shell strength.
Our manufacturing process and machines
were independently designed more than 40
years ago. Using these time-tested pro-
cesses and machines, Arai bonds togeth-
er various materials. By molding the shells
in-house, Arai creates helmet shells that
are strong down to their edges.
Arai's Preforma machine, created to pro-
duce the first and last foundational
layer of every Arai shell, has evolved as
part of Arai's constant efforts to improve
protection, and continues to evolve even
now. Currently, Arai is working to improve
the even distribution of fibers in order to
create uniform layers in the preforma by
using state-of-the–art digital techniques.
In this process, Arai cuts Super Fiber to
specified lengths, which is then drawn
over the form by a vacuum. The flow of the
fibers is controlled to efficiently scatter
the fibers in certain sections according to
the required thickness.
Arai's longstanding belief is that, "It is
better to accumulate improvements rather
than do nothing." As such, improvements
to the preforma come from Arai's desire to
protect the heads of its wearers.
Every helmet starts and ends with a preforma. The
special AR mat is used to make the shell lighter and
approximately 20 individual and unique components
are used in lamination depending on model and size.
From these components, an extremely strong shell
is prodced.
Compared to normal fiberglass, the "S" glass used in Arai's
preforma is over six times more expensive, but 30% stronger. This
Super Fiber, which is often used in aviation and aerospace, is used
exclusively by Arai for helmet making
