What are the misunderstandings in the production of water cups? (three)

In the first two articles, the editor talked about some production misunderstandings on the cup lid and itself. Today I will share the misunderstanding of the cup body spraying.At present, the surface spraying process of stainless steel water cups on the market is painting and powder coating (powder coating). Since powder coating appears later than spraying, there are still some production errors in powder coating.

Hanging spraying method should not be used in the spraying production of water cups.Because the spraying process mostly uses electrostatic adsorption, the stainless steel water cup hanging will cause the stainless steel water cup to not be level and flat, and will be inclined, so that the spraying will be prone to uneven spraying and inadequate spraying during spraying.

The most mature spraying process for stainless steel water cups is inverted spraying.The advantage of this is that the water cup is sprayed evenly and the spraying efficiency will be higher, and the fixture itself is easier to separate from itself after spraying at high temperature and drying.

Due to the better hand feeling, higher hardness and higher abrasion resistance after powder coating, many brands and purchasers are more inclined to adopt the powder coating process.However, it is not recommended to use the powder coating process in the smooth effect. The difficulty of production is one aspect, and the defective product rate is difficult to control.

At the same time, because the flat powder is more delicate and achieves the effect of matte paint, the viscosity of the powder is increased, and the fixture is not good and the cup body falls off after drying.If you must have a flat gloss effect or a flat matte effect, it is recommended to spray a flat paint or a matte paint.
