What do you mean by mesh and film thickness? For example, what does 500*350 mesh 15um mean?

Mesh refers to the density between the wires of the screen. The higher the mesh number, the denser the screen and the smaller the mesh. Conversely, the lower the mesh number, the thinner the screen. The film thickness refers to the actual thickness of the screen. 500*350 mesh, 15nm means that the mesh number of the screen is 500*350, and the screen thickness is 15um.

The mesh number indicates the mesh number of the standard sieve. In Taylor's standard sieve, the so-called sieve hole is the number of sieve holes with a length of 2.54 cm (1 inch), which is simply called mesh.

The production of screen printing screen was monopolized by foreign enterprises in the past because of its high precision requirements, such as Smart, SEFA, NBC and other well-known foreign companies. With the introduction of technology and equipment, domestic enterprises also produce high-grade silk screens.

Extended data:

Types and applications of screen printing;

Woven materials can be divided into metal mesh and chemical fiber mesh. Metals are generally made of stainless steel, which has the characteristics of high tensile strength and low elongation, but it is very expensive and not widely used.

Its chemical fiber screen printing is generally divided into polyester material and nylon material. The difference between them lies in the low elongation of polyester silk screen printing, small mesh deformation and high printing accuracy. Nylon material has its elasticity, can be used for printing non-planar materials, and has the characteristics of wear resistance.

From the weaving process, it can be divided into plain mesh and twill mesh. Compared with twill screen, flat screen has higher printing accuracy, while twill screen has higher tension.
