Vertigal integration process
The vertical integration process means Mitsubishi can make any combination of resins and fibers required to optimize a golf shaft's design and performance. The majority of their competitors, on the other hand, work with a relatively limited list of raw materials from a finite number of available suppliers. Typically they purchase stock prepreg, which can require designs to be adjusted to the limitations of the available materials. Mitsubishi's ability to make any composition of resin or fiber and combine them into their own prepreg sets them apart from the competition.

Technology Mitsubishi Rayon/Graphite Shafts
Mitsubishi Rayon construct the best golf shafts because the complete process begins with the production of the raw materials. They utilize state-of-the-art equipment, innovative processes, and the finest materials in the world to make their golf shafts.
Over the past 25-years, Mitsubishi Rayon has developed it's own proprietary knowledge base and software system specific designed for developing golf shafts. They understand that engineering a premium golf shaft not only involves maximizing performance, but also involves incorporating an aesthetic appeal that gives the player confidence.
 
Basic raw materials consisting of simple molecular structures (monomers) are combined to produce Acrylonitrile (AN). AN is then polymerized to form polyacrylonitrile (PAN). Mitsubishi Rayon uses the highest grade materials available to create AN and PAN.
 
A solution of PAN is then spun into precursor. The process of creating precursor heavily influences the quality and consistency of the carbon fiber - it is, in effect, the skeleton of the shaft. It is a process in which Mitsubishi Rayon has refined and perfected over the last 80-years.
 
Mitsubishi Rayon has developed many different resin systems that possess a variety of mechanical properties (e.g. high-heat resistance, strength, toughness).
 
Precursor is oxidized and carbonized in ovens to produce carbon fiber. Mitsubishi Rayon produces carbon fiber for a variety of different applications and is the 3rd largest manufacturer of carbon fiber in the world. The playing characteristics of each shaft model is really influenced here.
 
Carbon fibers are impregnated with resin to produce ready-to-mould material in sheet form. Mitsubishi Rayon produces a variety of different types of prepreg for many different applications (e.g. aerospace, sporting goods, etc.).
 
Different types of prepreg are then cut into specific patterns and rolled to create a composite golf shaft. Using the wealth of experience, data and feedback from the many tour players who use them, they are able to create exceptional performance for different swing types. Custom fitting will determine which model/flex/tipping instructions will suit you best.
