The QUATTRO FORGED FACE with 4 technologies combined
Four proprietary technologies are incorporated into a single cup face to expand area with stable and high rebound. The driver delivers a pleasant feel and powerful performance, all while providing bounce and capturing the ball.
ROUND rod forging that produces exceptionally strong and dense metalic structure
Round rod forging that produces exceptionally strong and dense metallic structure *Revolutionary In contrast to conventional drivers with a face made of rolled titanium sheet material, the C01D incorporates round rod forging, PROTOCONCEPT’s innovative technology. The metal structure becomes very dense, improving tensile strength, hardness, and tenacity.
Through incorporating the round rod forging method, the titanium crystals have a more dense and uniform structure, creating a forged line (metal flow) in which metal particles are aligned and improving strength while providing a soft yet secure feel when hitting.
#01 Round rod forging
Forged line created with Spheres
Outstanding technology in high-precision press work
#03 Finish FOrging
The excess surrounding parts that were molded into the cup face in the previous process are removed. Due to the high precision of the manufacturing process, there is little margin needing removal.
The final pressing is done with a load of 500 tons.
The complex shapes with thickness deviation can be produced as designed with high-precision forging, which minimizes errors in thickness and weight and reduces the need for polishing work to the very least.
#5 Face Polishing
High precision face crafted with no "trimming down" required
