Sealing performance

The Vacuum process is an important technology used in the manufacture of wholesale stainless steel water bottles. The process insulates the inside and outside of the container to form a vacuum layer to achieve heat preservation or cold preservation.

During the production process, the vacuum environment is created by pumping out between the two wholesale stainless steel layers, and the sealing treatment is carried out using high-temperature sealing technology to ensure the stability and lasting maintenance of the vacuum layer.

This design effectively reduces heat conduction and heat radiation, preventing the loss or entry of heat, and thus maintaining the temperature stability or cooling effect of the drink over a period of time.

Thickness control

Wholesale Stainless steel water bottles are usually manufactured in two different thicknesses: single and double. The single-layer water bottle is generally made of a layer of wholesale stainless steel material, and the double-layer water bottle is composed of a vacuum layer between two layers of stainless steel material, which has been designed to reduce the influence of the external temperature on the temperature of the liquid in the bottle, effectively ensuring the quality of the liquid.

Coating treatment

In addition to thickness control, the internal coating of the water bottle is also one of the key concerns. High-quality stainless steel water bottles are usually made of food-grade 304 stainless steel material and specially treated to improve its corrosion resistance and anti-bacterial, this internal coating also protects the purity of the water.

Vacuum insulation process

The vacuum insulation process of wholesale stainless steel water bottles is realized by creating a vacuum layer between the inner and outer bottle walls.

The vacuum insulation process mainly includes the following steps:

(1) Manufacturing the inner and outer walls: Wholesale Stainless steel water bottles usually consist of two layers of stainless steel walls, the inner wall is responsible for storing liquids, and the outer wall is used for protection and isolation.

(2) Create a vacuum layer between the inner and outer walls: The manufacturing process will form a vacuum layer between the inner and outer layers of the bottle wall, through the evacuation process to make it into a vacuum state.

(3) Sealing the bottle mouth: After the manufacturing process is completed, the bottle mouth needs to be sealed to ensure that the vacuum state is not disturbed by external gases.

What is a spraying line

A spraying production line is a whole line of machinery and equipment used for metal surface treatment of goods and can be used to spray products, powder coating, gold-plating, and other chemical substances, to achieve the effect of a beautiful and generous or maintenance.

Automatic multi-functional intelligent production line process

The pre-treatment of the workpiece can be carried out on the conveyor chain in the following ways: shot blasting, sandblasting, spraying, groove dipping, etc. The pre-treatment of the workpiece can be carried out on the conveyor chain.

After pre-treatment of the workpiece with the chain drive into the powder spraying room,an automatic powder spray gun for powder coating of the workpiece, and the powder spraying room supporting the recycling device can also be equipped with a fully automatic clearing powder for the color of the big cyclone powder recycling device.

After spraying the workpiece continues to run to the high-temperature furnace for powder melting and curing, The high-temperature furnace runs out of the run to continue to run after cooling, cooling the next piece, complete the process.

According to the customer’s request, it is also equipped with environmental protection equipment, so that the smoke emitted from the high-temperature furnace is purified by the environmental protection equipment and becomes a harmless gas emission into the atmosphere.

Manual spraying common production line process

Pre-treatment of the workpiece can be taken to phosphating solution wiping dirt, sanding with an angle grinder to remove rust, sandblasting treatment of oil rust, etc., and then on the piece to the chain of the hangers run to the ordinary powder spraying room, the staff holding a powder spray gun on the workpiece for the powder spraying, after spraying the workpiece continues to run to the high-temperature furnace for the melting and curing of the powder, run out of the high-temperature furnace and continue to run after the cooling, cooling down the next piece, to complete the process.
