Custom Open Die Forged Cylinder for Mechanical and Hydraulic Systems
Our custom open die forged cylinders are designed to meet the demanding requirements of mechanical and hydraulic systems operating under high pressure, repetitive motion, and heavy loads. Manufactured from premium carbon or alloy steel, each cylinder is forged with a controlled grain structure to improve internal strength and fatigue resistance. With flexible sizing, material selection, and optional machining services, we deliver fully tailored components for critical industrial applications.
