Forged Hydraulic Cylinder Components

What is the process of Forging ?

Forging is the process of working or forming metal to the desired shape by impact or pressure from hammers, presses or forging machines. The metal object produced through this process is termed a forging.

Forging Advantages ?

Forgings are superior over castings and fabrications as the structural integrity can withstand the higher forces that exist in a rigorous or high duty cycle application.

Why Choose Forging ?

Forgings are best used in high duty cycle or more rigorous applications where a more durable, high quality hydraulic cylinder is required. This could be within markets such as construction, mining, refuse etc. Forged hydraulic cylinder components provide the best impact resistance due to the improved directional strength of the grain structure created through the forging process. Forgings can also reduce cost in material, machining and even warranty due to it's superior quality.

FORGED COMPONENTS SLIDESHOW   

Forging Provides:

  • 1
    STRUCTURAL STRENGTH
    Forgings provide exceptional structural integrity which in turn will ensure the component will withstand and exceed the application requirements. This reliability will reduce warranty claims and promote safety.
  • 2
    DIRECTIONAL GRAIN FLOW
    A forged component such as a hydraulic cylinder rod, trunnion, etc. produces a directional grain flow that improves the mechanical properties of the metal. The process will produce a predictable grain flow that will result in improved mechanical properties best suited to match the intended application.
  • 3
    IMPACT STRENGTH AND FATIGUE RESISTANCE
    This directional grain flow assures maximum impact resistance and fatigue, this will extend the service life of the component and the efficiency of the application.
  • 4
    MANUFACTURING EFFICIENCY
    In many cases forged hydraulic cylinder components are formed closer to the finished sizes in comparison to fabricated metal components, plate or barstock. This potentially reduces machining time and increases manufacturing efficiencies.
  • 5
    REDUCED REJECTION RATES
    Forged hydraulic cylinder components are weld free. The higher quality of the material and one piece construction improves upon the structural integrity which reduces reject costs and warranty claims.

A Forged component in a hydraulic cylinder could be any of the following:

Hydraulic Cylinders Rod
End Cap Assembly
Barrel Or Tube
Piston
Gland
Clevis
Trunnion
Flange

Forged Hydraulic Cylinder Components Provide:


  • Excellent metallurgical properties, very consistent results
  • Directional grain flow and superior strength
  • Improved structural integrity and product reliability
  • The elimination of welding results in a much stronger cylinder rod or component
  • Heat treatment requirements will provide improved and more stable results
  • Manufacturing requirements are simplified
  • Reject, rework and replacement costs are greatly reduced
  • Reduced warranty cost, improved warranty


Grain Flow Comparison


FORGED BAR
A forged bar contains a directional alignment that is oriented in the direction to achieve maximum strength. This grain flow will yield ductility and resistance to impact and fatigue.
MACHINED BAR
A machined bar contains a unidirectional grain flow due to the changes in contour and exposed grain on the ends. This is more prone to fatigue and more sensitive to stress corrosion cracking
CAST BAR
A cast bar contains no grain flow or directional strength.
