Pistons are produced via gravity casting or hydraulic forging, followed by a heat treatment process. Machining is completed using CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes rigorous quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction. A new Phosphate Coating offers increased hardness, surface porosity, and improved adhesion and durability compared to the Molybdenum Coating.
