Slogan painting mold

1. For products without spraying texture, the number of spots that may be caused by oil or dust on the products depends on their diameter and distribution. According to the surface gloss, we suggest:

φ≤ 0.3mm, d≥ 10/0mm, OK.

1.0mm ≥φ 0.5mm, d ≥ 50mm: 4 points are allowed; (d = distance between two points)

0.5 mm ≥ φ 0.3 mm, d ≥ 25mm: 8 spots are allowed;

Otherwise condition, NG

For products that do not bite flowers and spray oil, the diameter and distribution of stains (which may be caused by oil or dust) determine the quantity. We will determine the acceptance standard of the product stain quantity according to the surface smoothness of the product. Specific suggestions are as follows:

I didn't say what your gloss requirement was. )

There is another impurity on the product. It is silk made of dust or cloth fibers. According to their length, we suggest:

2.0mm ≥ l "1.5mm, d ≥ 40mm: 4 threads are allowed; (d = distance between two silks)

.....

There is also a surface impurity, which may be filaments caused by dust or clothing fibers. We will determine the acceptance criteria for the quantity of silk products according to their length (L). Specific suggestions are as follows:

3. It is necessary to test the paint adhesion (cross test). Our question is whether to use 3M600 for the test. Besides, do you have any other test requirements, such as wear resistance and solvent resistance?

It is necessary to test the adhesion of spray-painted products (100 bar test). Our question is, do we use 3M600 for testing? Besides, do you have any other test requirements, such as abrasion resistance test and solvent resistance test?

The fourth point is a bit unprofessional, and the fifth point should be raised in the first point. There is no time. Maybe next time. In addition, add some points, tired.
