[0002] The gas spring is an industrial accessory which can play the functions of supporting, buffering and braking, and is mainly applied to cover and door parts and various automobile shock absorbing components. The quality of the gas spring is mainly considered from the following aspects: first, the sealing property. If the sealing property is poor, oil and gas leakage will occur during use, and the main cause of the problem is usually the burr inside the gas spring steel pipe. Therefore, the burr inside the gas spring steel pipe will directly affect the working performance of the gas spring.
