Machined to Withstand Force and Flow

Hydraulic systems demand components that can withstand extreme pressure, fluid dynamics, and constant mechanical stress. At Nanjing Precision Engineering Co Ltd, we supply high-strength, precision-machined parts for a wide range of hydraulic applications — from valve bodies and fittings to pump housings and connection tubes. With advanced CNC machining services, CNC tube bending services, and tight-tolerance sheet metal fabrication services, our solutions ensure leak-proof performance, structural durability, and seamless integration into high-pressure hydraulic systems used in industrial equipment, construction machinery, and automation platforms.

What is Hydraulic Components Machining?

Hydraulic components machining is the precision manufacturing process of producing high-performance parts used in hydraulic systems—such as valve blocks, cylinder components, manifolds, fittings, and piston rods—through methods like CNC machining, milling, turning, and drilling. These components must meet tight tolerances, high-pressure durability, and leak-proof performance standards to ensure the reliable flow and control of hydraulic fluids in demanding environments. Leveraging advanced machining technologies and rigorous quality control, hydraulic components machining is essential for ensuring system integrity, efficiency, and safety across applications in automotive, aerospace, heavy equipment, and industrial automation sectors.
