Three spraying methods during sheet metal processing

In the process of Sheet Metal Processing in Shenyang, if the internal space is small, such as internal welding, welding gun should be considered. 6.2 If the thickness is less than or equal to 1mm, it is prone to shortening or burning after welding, which is caused by welding deformation. The main three spraying methods are as follows:

Flat light: can be divided into sub light, flat light, and high light, with a coating thickness of about 60-90 meters and a coating thickness of about 90-120 meters after spraying

Sandprint: can be subdivided into fine sand and coarse sand. The thickness of the spray coating is about 50-80 μ m, which is about 80-110 meters before injection.

Orange pattern: can be divided into small orange pattern and large orange pattern. The spraying thickness is about 90-120 μ m, and it is injected approximately 120-150 meters later.

The coating thickness will exceed the above-mentioned thickness.

1. Flat light: Advantages: Beautiful appearance, good printing effect; Defects: High cost, high spray repair rate, easy to scratch, scratch the surface, unable to repair, and difficult to spray high gloss during the process. Try to avoid using light as much as possible, especially in situations where it is easy to handle protrusions on large chassis.

2. Sandprint: Advantages: Not easy to scratch, low spraying cost by three; Defect: The outer oil is easy to remove, and the printing effect is not as good as ordinary orange peel.

3. Orange pattern: Advantages: Not easy to scratch, good printing effect, easy removal of surface oil, spray coating cost slightly higher than sand particles, but much lower than plains. Defect: The aesthetic level is slightly lower than that of the plain.

4. The paint color should be as uniform as possible, using the main product colors of our company to facilitate the supplier's ordering of powder.

5. Try to use one spray color as much as possible to reduce spray costs, greatly improve processing time, and reduce the probability of supplier coating errors.

6. The use of silver powder should be avoided. Silver powder is a compound containing silver, and its price is twice that of regular powder. It is difficult to spray and prone to producing defective products.
