Hydraulic Cylinder Forgings & Mechanical Assembly
Weforging delivers comprehensive manufacturing solutions for hydraulic components, including cylinder barrels, pistons, glands, end caps, and piston rods. We process carbon steel, alloy steel, and stainless steel, ensuring optimal mechanical strength and corrosion resistance across various industries. Our integrated facilities combine CNC machining, heat treatment, and precision assembly, supporting both small and large batch production for OEM and customized projects. Under strict ISO 9001 quality management, Weforging ensures full forging and assembly integration, guaranteeing reliability and consistency in every part.
Hydraulic Cylinder Product Range
Weforging manufactures a wide range of hydraulic cylinder forgings designed for diverse industrial applications. Our product lineup covers both standard and customized configurations to meet different performance and load requirements:
Cylinder Barrels — Hot-forged and precision-machined barrels with high internal pressure resistance and smooth inner surfaces for optimal sealing performance.
Piston Rods — Induction-hardened and chrome-plated rods providing exceptional wear resistance, surface finish, and load stability.
End Caps & Glands — Forged from high-strength alloy steel for enhanced durability and secure sealing under variable pressure.
Pistons — Machined for tight tolerances to ensure efficient power transmission and smooth operation in hydraulic systems.
Complete Cylinder Assemblies — Fully assembled and tested hydraulic units for OEM applications in construction, mining, and energy equipment.
These components are available in carbon steel, alloy steel, and stainless steel, with customized dimensions, coatings, and connection types to suit specific engineering requirements.
Hydraulic Cylinder Forging Process
The hydraulic cylinder forging process at Weforging follows strict, step-by-step control to ensure precision, strength, and traceability throughout production:
Billet Selection & Cutting — High-quality alloy or carbon steel billets are selected and cut to the required length.
Heating — Billets are uniformly heated to 1050°C–1250°C to achieve optimal plasticity for deformation.
Closed-Die Forging — Under controlled pressure, heated billets are forged into dense, uniform shapes with refined grain flow.
Heat Treatment — Each forging undergoes normalizing, quenching, and tempering to enhance strength and fatigue resistance.
CNC Machining — Advanced turning, milling, and drilling operations ensure tight tolerances and smooth surface finishes.
Inspection & Testing — Every part is verified through ultrasonic, hardness, and dimensional inspections for full quality traceability.
Mechanical Assembly Services
Weforging’s mechanical assembly capabilities enable seamless integration of forged and machined components into high-performance hydraulic systems. The process involves precision assembly of pistons, rods, seals, glands, and housings under strictly controlled torque and cleanliness standards. Each subassembly undergoes leak and pressure verification to ensure optimal sealing performance and durability. With accurate tolerance management, all components maintain precise alignment and smooth functionality. Additional services such as surface finishing, labeling, and corrosion-resistant packaging ensure every hydraulic cylinder assembly is delivered installation-ready and built for extended service life.
Technical Advantages & Quality Control
Weforging integrates forging, machining, assembly, and testing into one unified production system for superior precision and traceability. Each stage of manufacturing is monitored under a ISO 9001:2015-certified framework with comprehensive material certification and process tracking. Our facilities utilize CMM inspection, ultrasonic testing, and fatigue analysis to maintain tight tolerances and consistent structural integrity.
