I The measures of Guarantee waterproof & air tightness:
1.1 Welding completely & penetration: firmly wipeout false welding.
1.2 WIFI interface:
2.1 stamping die for the whole to ensure level and consistency;
2.2 welding with the clamp for positioning ;
2.3 Full inspection :see nothing under the light.

1.3 Guarantee the smooth of the bottom:
3.1 Incoming material control: aluminum plate: inspect each lot--- hardness 7 degree, ensure the consistency of bending coefficient.
3.2 Press and riveting positioning die to ensure concentricity & smooth.
3.3 Full inspection of the flatness:gap within 0.5 mm.

2 process:
2.1 welding
1.1 12 professional process of aluminum welding.

2.2 Polishing:
2.1 the first process: rough polishing: polishing the mark of welding.
2.2 the second process: precision polishing: fine, smooth.
2.3 the third process:air mill: ensure the surface smoothness & perfection.
2.4 assembly line of polishing manipulator, and 12 employeers of polishing.

Spraying 2.3:
2.3.1 the self-owned spraying factory,passing the environmental impact assessment,ensuring the continuous and stable supply.
2.3.2 professional aluminum spraying process, special powder for the aluminum spraying, pickling + passivation ( phosphating for iron), ensuring the long-term adhesion of aluminum surface.
2.3.3 thickness: 40-120μm, ISO revision: 1 ,hardness: 1H.
2.4 fully automatic welding (in the second half)
