Chair Gas Cylinder Manufacturers: What Are the Necessary Facilities?
Necessary facilities for gas cylinder manufacturing
As a chair gas cylinder manufacturer, we are always requested to offer the Office Chair Gas Cylinders which should be durable and safe by our clients. In the following content we are going to introduce the indispensable facilities in a gas cylinder factory.
The chair is for sitting. In all the office chair parts components, more closer to the body, the ergonomic issue is necessary to be considered.

1. For Tube Cutting:
Cutting machine: the seamless steel tubes arriving at warehouse, need to be cut into the right size according to customers’ order.
2. Surface Polishing and Concentric Machine:
During the transportation, the tube may get bending and scratches on the surface, which will affect the piston working inside.
If the piston with an o-ring working in one bending tube, the gas will leak sooner or later.
Meanwhile the scratches inside the tube will hurt the o-ring, and it will lead to leakage as well.
This machine will concentric the tubes and polish the surface finishing.
Comparing before and after this step.
3. Curling one end and engraved thread the other
4. Ultrasonic Cleaning
The ultrasonic cleaning is necessary, because in the machining process, the oil is everywhere in the tube and in the machine. Without this machine, the dirty especially the oil can’t be removed.
All these clean and polish steps will ensure the duration of the chair gas cylinder, and it should be completed carefully and strictly.
5. Assembly machine line
For the assembly part, each chair gas cylinder manufacturer will design his own line according to its situation. The mass production is asking for a high level-auto machine line.
During these steps, the auto- assemble machine line is not 100% necessary, higher auto level, more quantity request in the MOQ.
The video on the left is one part of the assembly by manual.
Manual assembling for the final assembly:
As chair gas cylinder manufacturers, we should pay attention to the followlling points:
(1) The gas pressure test: 3 times during the production:
- 1st time: injection Nitrogen
- 2nd time: inner-cylinder placed for a time to check whether the gas is leakaging or not.
- 3rd time: after the layout and before assembling with the out-cylinder, normally this step will combine together with printing(some clients may request their own logo remark )
(2) The high-press gas should be 100% Nitrogen
(3) The inner tube of the gas cylinder must be 100% seamless steel tube.
(4) The test should be applied all the time to meet the BIFMA certified.
