Design and Manufacturing
Material: Generally speaking, chrome plated piston rod is made with high strength carbon steel (SAE1045) or stainless steel (304/316)through high-temperature forging which can ensure its density and strength and to adapting to in all kinds of bad using conditions, considering the factors of economy and wear resistance. Hollow design for weight saving and structure security.
Chrome Plating : Thicker than 20 micron for more corrosion resistance, decrease friction and increase surface hardness (up to HV850). This also guarantees a fine surface finish (Ra ≤0.2μm) for perfect sealing with gas spring components.
Precision Machining: chrome plated piston rod specialized processes such as honing and polishing are utilized to attain precise tolerances (ISO f7/h8/g6) and straightness (≤0.2/1000mm).
Uses in Gas Springs
Automobiles & Furniture Application: chrome plated piston rod is mostly used in automotive seats, like trunk lids, and in lifting or rocking device of furniture,as a mechanism for games machines,sports equipment, and more.
Industrial Machinery: 10mm chrome rods are used in hydraulic systems, as vibration dampers, in robotic arms to transmit precise force.
High-Performance Situations: For instance, in high speedy rail seats, the chrome plated piston rod can be used for angle adjustment and can retain locks with little maintenance.
Corrosion Resistance: Chrome plating, along with other rust-resistant treatments (e.g., oil coating), deliver maximum durability for withstanding harsh marine or high-humidity environments.
Weight Loss: With the hollow structure, the system’s weight is decreased, which is important for uses such as aerospace and automotive engineering.
High Torsion Load: Capable of withstanding tensile forces of up to 5,000 N (e.g., ACE industrial gas springs), which means high load capacity for heavy duty applications.
