Chrome Plated Rods
Chrome Plated Rods are produced from medium carbon cold-finished or hot rolled steel bars usually in Steel 1045/1050 or 10v45 grades. The bars need to be polished, and chrome plated to a minimum thickness of 0.0005", and 0.001" per side. Chrome Plated Rods are specifically designed to be used for most piston rod applications in hydraulic cylinders.
Nikrom Rod
As some of customers' machines working environment is highly corrosive conditions, which required very high corrosion resistance. Ningbo LD provides an option of Nikrom rod.
Due to the presence of natural micro cracks in the chromium layer, erosion may penetrate the coating. In corrosive environments or strictly safe applications, exposure to the risk of mechanical damage, oil film alone is not enough to protect in the field.
This is especially true if the piston rod remains elongated for a long time as the oil film dries out. By combining the chromium plating with the lower nickel layer. Nikrom can greatly improve the corrosion resistance regardless of the overall oil film protection state of the piston rod.
Nitrided-Treating Rods
Compared with chrome plated rods, Nitrided rods' black colored surface finish is very hard, and the hardness can be above 55 HRC. The process of liquid nitriding begins with the cleaning and super-polishing of the material to a surface roughness of 6 to 10 Ra.
The improved corrosion resistance can reach the requirements of 500-1000 Hours by Salt Spray Testing (ASTM B117), the nitrided rods are normally sufficient to protect the shaft during its entire life. Nitrided rods are cost effective alternative way for longer time salt spray testing requirements.
3.Casting Fabrication For Hydraulic Cylinder Components
Ningbo LD has over 30 years experiences in casting fabrication. We have great flexibility in offering cast components in our hydraulic cylinder designs. Cast components are made from pouring molten metal into a pre-engineered molds that produces a specific shape or form. The most common cast items in our hydraulic cylinders are rod clevis or base end clevis as well as customized end caps.
The benefits of Casting components :
Cost Saving
Reducing welding processing steps for complex shapes
Better finish looking
Excellent machinability with increased strength
Repetitive and precise process
4.Forging Fabrication For 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.
The benefits of Forging components :
Superior strength with directional grain flow
Excellent metallurgical properties with very consistent results
Improved structural integrity and products' reliability
The elimination of welding results in a much stronger cylinder rod or component
Simplifying the manufacturing requirements
Reject, rework and replacement costs are greatly reduced compared with casting
Reduced warranty cost, improved quality warranty
