United States Technology, or better known as UST, designs, manufacturers and markets innovative, high performance golf shafts in the world. USTs flagship ProForce Series, which includes the V2, HMOI, High Launch and Proforce Classic, is the number one selling line of graphite replacement shafts in the world and one of the most popular on the PGA and European Tours. Starting with the 1999 Masters victory, the Proforce brand has continued its winning ways on tour and at the club.
With state-of-the-art manufacturing facilities in the U.S., China and Bangladesh and offices in the U.S. (California and Texas), Japan, Australia and Europe, UST Mamiya engineers work with club manufacturers around the world to create the most innovative graphite shafts sold. Our test markets are the professional golf tours around the world, and our success includes multiple wins at every major.
UST Mamiyas headquarter in Fort Worth, Texas, U.S.A., is supported by a global network of engineering, marketing and manufacturing facilities. Brands include ProForce, IROD (the worlds first hybrid shaft), the innovative Frequency Filtered putter shaft and the Competition Series shafts.
UST Mamiya makes graphite golf shafts for golf consumers and supplies many original equipment manufacturers, such as Adams, Bridgestone, Callaway, Cleveland, Cobra, Nike, PING, Titliest, Wilson, and others. UST Mamiya also produces and distributes such world-renown graphite shaft brands as Proforce, AXIV, IROD and Frequency Filtered putter shafts which are played in more than 100 tour events on the PGA, SPGA, Nationwide and European tours. Headquartered in Fort Worth, Texas, UST Mamiya maintains four operational facilities throughout the world and has produced more than fifty million graphite shafts for original equipment manufacturers and makers of golf club components.
AXIV Technology:
AXIV technology in the recently introduced Proforce AXIVCore Series is a UST Mamiya exclusive, proprietary process of weaving specific high-modulus carbon fibers in the critical four axis directions necessary in shaft design to optimize stiffness, hoop strength, and torsional resistance, all in a single ply. The AXIV material resists deformation allowing the shaft to maintain consistent symmetry. The Proforce AXIVCore Series feature Blue, Tour Black, Tour Red models and are now available in multiple weights and flexes to fit various swing profiles. The Blue is for the player seeking additional spin for longer carry distance, while the Tour Black is for the player seeking high launch, low spin and more ball speed. The Tour Red is for those players needing very stable golf shafts that produce a penetrating ball flight with low spin. These counter-balanced models also reduce club heft to help players generate more club head speed for more ball speed resulting in longer drives.
UST ProForce Tip Technology:
With the premise that golfers would benefit from playing a low torque shaft, the question facing UST engineers is how to design them so that Tour pros and average golfers can actually get them airborne with the most amount of feel. The answer rests in our Proforce Tip Technology’s more responsive tip section. With our Proforce Tip Technology, we can match-up the launch conditions of the head to the shaft. We have the ability to make the tip section stiffer or more flexible. UST started the tip-stiff movement of the late 1990s with the launch of the popular Proforce Gold shaft. Back then, the industry produced wound balls that featured higher spin rates and shallower face drivers that increase spin than today. The result is golfers were looking for a shaft to keep the ball down. Today, solid balls and low-spinning, oversized drivers are the norm. Shaft designers are now trying to keep the ball in the air. The optimum design features a softer tip section that responds to the individual golfer, all to generate lower spin with higher initial launch conditions. The result is a higher ball flight and more ball speed because the tip section is now traveling faster through the hitting zone. And because the flexural, bend profile is softer in the tip and butt sections, golfers will experience better feel.
