Aluminum bottle base design
When the aluminum bottle is designed with a base structure, it should ensure that the base has sufficient strength and the base material should be compatible with the material of the bottle body. The base shall be cylindrical in shape and shall ensure the upright stability of the aluminum cylinder. The connection between the base and the bottle body should not be welded, and the structure should not cause water accumulation.
Aluminum gas bottleneck ring design
When the aluminum bottle is designed with a collar, the collar shall be of sufficient strength and the collar material shall be compatible with the bottle material. The collar should not be welded to the bottle body. The axial pull force of the collar shall not be less than 10 times the weight of the empty bottle and not less than 1. 0. N, rotational torque shall not be less than 100 Nmo

Aluminum bottles of cylinder
The bottle body is made of ingot and extruded bar as raw materials by cold extrusion or hot extrusion or cold drawing after extrusion.
The bottle body is made of pipe material by spinning process.
The bottle body is made of sheet metal by stamping, drawing and spinning.
Aluminum cylinder ends
Shoulder can be molded or spinning closing process.
The surface of the transition between bottle mouth and bottle shoulder should be smooth without mutation or obvious wrinkles.
The end should be heated evenly during the forming process to ensure that the material has no over-burning structure.
No welding shall be performed.
Aluminum alloy cylinder group batch
Manufacturing shall be managed in batches, each batch not more than 200 plus the number of destructive test bottles.
