Premium OEM Hydraulic Cylinder Solutions
Hydraulic cylinders are key power components that convert hydraulic energy into linear motion in heavy machinery and industrial systems. At Weforging, we produce precision-forged hydraulic cylinders that combine exceptional mechanical strength, sealing reliability, and corrosion resistance. Through integrated processes—forging, CNC machining, heat treatment, and surface finishing—each component achieves high dimensional accuracy and long-term durability, even in high-pressure and high-load conditions.
What Is a Hydraulic Cylinder Forging
A hydraulic cylinder forging is created by deforming heated metal under controlled pressure to refine its grain structure. Unlike cast or welded cylinders, forged types eliminate internal voids and impurities, resulting in stronger, more reliable components. This process ensures uniform microstructure and optimal fatigue resistance, making forged hydraulic cylinders ideal for use in construction, mining, and marine systems that demand both power and endurance.
Manufacturing Process at Weforging
Weforging follows a systematic production process to ensure every hydraulic cylinder forging achieves structural integrity and dimensional accuracy.
The main steps include:
Hot Forging – Heated alloy or carbon steel billets are formed under controlled pressure to match the designed stress flow lines. This step refines the grain structure and increases core strength.
Heat Treatment – Each forged blank undergoes normalizing, quenching, and tempering to balance hardness with ductility, improving fatigue resistance and overall durability.
CNC Machining – Precision machining ensures tight bore alignment, accurate threading, and smooth sealing surfaces. This guarantees efficient motion and leak-free operation.
Surface Treatment – Final coatings such as chrome plating, nickel coating, or phosphating are applied to enhance corrosion resistance and wear protection, especially for cylinders used in high-humidity or saltwater environments.
Inspection & Testing – Ultrasonic, dimensional, and hardness tests are conducted to verify structural integrity and meet ISO 9001:2015 standards before shipment.
