Air is prone to oxidation inside the gas spring, causing rust inside the tube body, which is not conducive to product stability and long-term use needs. The inside of our gas springs is nitrogen, which is an inert gas and is not prone to chemical reactions.
Yes. Our gas springs are all REACH-compliant and manufactured in accordance with the RoHS directives, and ISO 9001 / ISO14001.
Our gas springs can pass the 96-hour salt spray test, and if they are made of stainless steel, they can pass the 120-hour salt spray test.
We have engineers with 15 years of experience in the gas spring industry who can provide technical support from the development stage to the post-production stage, and design gas springs to meet customer needs.
No, the pressure cannot be increased or decreased after the gas spring is produced.
The gas spring piston rod should be installed in a downward position as far as possible, not upside down, to reduce friction and ensure the best damping quality and cushioning performance.
You can find our catalog in DOWNLOAD, there is a calculation method in the last pages. Also you can contact me directly.
No. The ambient temperature range of gas springs is: -20 to +60 ℃ (specific manufactured gas springs can be used in 80 ℃)
The industry standard for gas springs is 28,000 times, and ZHILI gas springs can be used at least 50,000 times.
Normally it is 100PCS
Neutral salt spray tester, projector, seal auto tester, gas spring pressure tester, gas spring life tester, gas spring curve tester ......
Yes, the gas spring in the normal state of the rod is extended
The minimum pipe diameter of ZHILI gas spring is 12mm and the minimum pressure is 5N.
f the gas spring is not broken, the main reason why the gas spring piston rod cannot be compressed is that the external pressure is not enough to push the piston rod into the gas spring body.
Adjustable gas springs are divided into flexible adjustable gas spring and rigid adjustable gas spring
FLEXIBLE means the rod may slightly “flex” under heavy compression or tension loading. These springs must be used in a rod-down orientation unless an “oil chamber” system is fitted.
RIGID IN EXTENSION means no flex when rod is being pulled, slight flex when rod being pushed. These springs can be used in any orientation.
RIGID IN COMPRESSION means slight flex when rod being pulled, no flex when rod is being pushed. These springs must be used in a rod-down orientation unless an “oil chamber” system is fitted.
The most significant difference is the locking force which the loading force when the gas spring is locked. The rigid adjustable gas spring has better locking function, and the maximum locking force can reach 1500KG.
ZHILI adjustable gas springs with a minimum stroke of 24.5 mm
The self-locking gas spring has only two states, the rod is fully extended (unlocked state) and the rod is fully compressed into the tube (locked state), and the stroke length is fixed when used.
To unlock the self-locking gas spring, simply press the gas spring down to release the compression and the stroke returns to its natural extended state.
The minimum pipe diameter of self-locking gas spring is 15mm and the minimum pressure is 50N
Yes, the internal gas of the gas traction spring is also high purity nitrogen, and its functional specificity is due to the structural problems of the internal fittings.
The piston rod is extended when the reaction force is greater than the pressure inside the gas traction spring.
The forces of the gas traction spring F1 and F2 are relatively close to each other, F1: F2 ≈ 1:1.2, which is suitable for applications requiring close force values at both ends
Although the appearance of metal dampers and gas springs is the same, metal dampers do not have a support function; their main function is to reduce the impact force and bring cushioning function.
Metal dampers are divided into compression direction damping, tension direction damping and bidirectional damping.
No, the lateral force will easily damage the metal damper, affecting the use effect and service life.
ZHILI factory has more than 8 sets of injection machines, which can be customized according to customers' requirements and produced independently.
No, inside the damper, in addition to the spring, there are other accessories such as seals, silicone oil, etc. The mature structure provides a stable damping effect.
The inside of our plastic dampers are environmentally friendly silicone oil.
The common dampers on the market are constant damping, the advantage is the low cost, our dampers through the design of the internal structure to achieve the effect of variable speed, that is, in the damping value will change according to the strength of the impact received, thus allowing your product to achieve a stable effect.
