Manufacturing process

Process 1Cutting

Best materials and precise cutting

The best materials developed jointly with a carbon fabric manufacturer are precisely cut according to measurements corresponding to each part used for the shaft.


Process 2Winding

Manual work performed by seasoned artisans

The work involved in winding carbon fabric around an iron core known as a mandrel is manually performed by seasoned artisans.
The ability to master the delicacy of rolling up a properly aligned highly elastic carbon sheet, which can be very difficult to handle, is the very essence of craftsmanship.


Process 3Thermal treatment

Thermal treatment to harden resin

After eliminating minute amounts of air from inside the shaft and applying tape to enable a clean form to be fabricated, thermal treatment to harden the resin is undertaken.
The duration and temperature settings for this process comprise a part of the company’s know-how as based on research results obtained over the course of many years of operation.


Process 4Shafts abrasion

Careful polishing raising by the artisan

After the mandrel (iron core) is extracted and the tape is removed, the surface of the shaft is polished.
Once a machine is first used to roughly grind the shaft, an artisan will patiently apply the finishing touch to each individual shaft by polishing it with sandpaper.
The latest ARMRQ shafts were brought into existence thanks to the craftsmanship required to carefully polish the quadraxial fabric (Specialty Continuous Non-Woven Fabric, SOF®) that forms their outermost surface.


Process 5Shafts coating

Coating with a material that weighs as little as a fraction of a gram

The coating work corresponding to the final process is carried out by hand.
At first glance, one might believe that it would be better to perform this task using machines. While an outsider could be excused for thinking that coating work is simple, the truth is that it demands a level of sophisticated craftsmanship to accommodate the highly delicate challenges that it poses.
Coating a shaft with a material that weighs as little as a fraction of a gram per unit requires making the coating as thin as possible while strengthening it and finishing it in an aesthetically pleasing manner.
It takes at least three full years to become a competent coating expert.
This too is an area on which a great deal of focus is placed by Honma.
