- Mold Aid:
For special shaped tanks, mold-assisted molding may be required to ensure dimensional accuracy.
4. Welding process
- Argon arc welding (TIG welding):
TIG welding technology is used to ensure uniform and firm welds to avoid defects such as porosity and cracks. Use inert gas (such as argon) to protect the welding process and prevent oxidation of stainless steel.
- Seamless welding:
The box adopts seamless welding process to ensure that the seams are smooth and free of dead ends, avoiding bacterial growth and leakage problems.
- Internal weld treatment:
The weld seams inside the tank are ground and polished to ensure a smooth surface for easy cleaning and maintenance.
5. Fitting Installation

Make holes in the designated position of the water tank and install the fittings such as water inlet, outlet, overflow, drain, etc. to ensure good sealing of the interface.
- Level meter or sensor installation:
Install liquid level meter or water level sensor as needed to facilitate real-time monitoring of water level in the tank.
6. surface treatment
- Polishing treatment:
Polishing treatment on the internal and external surfaces of the water tank to make it smooth and bright, which is not only beautiful, but also prevents dirt from adhering.
- Acid washing passivation:
Pickling passivation treatment for welding parts and surfaces, removing the oxidized layer and forming a protective film to enhance corrosion resistance.
- Sandblasting (optional):
Part of the surface of the water tank can be sandblasted to form a matte effect and enhance the appearance of texture.
