Dashang Wire Mesh New Product Series

Stainless steel wire mesh and tungsten wire mesh are mainly used for high-precision screen printing in the printing industry. In screen printing technology, these materials are widely used because of their unique physical and chemical properties.

1. **Application and characteristics of stainless steel wire mesh**:

- Stainless steel wire mesh is widely used in the printing industry for its excellent plane stability and stability of the size of the produced graphics. Especially in occasions where high-precision printing is required, such as printed integrated circuits, thick film semiconductors, etc., stainless steel wire mesh can ensure the accuracy and consistency of the pattern during the printing process.

- Stainless steel wire mesh has the characteristics of high permeability, positive pore structure and a 90-degree angle between the two diameters of the adjacent edges. These characteristics enable stainless steel wire mesh to provide uniform ink transfer during the printing process, ensuring the consistency and high quality of printing quality.

- Under high tension, the degree of stretching of stainless steel wire mesh is very small, which means that the shape and size of the wire mesh can remain highly stable even under long-term and high-intensity use conditions. This feature is particularly important for long-term printing operations, which can greatly reduce printing deviations caused by screen deformation.

2. **Application and characteristics of tungsten wire mesh**:

- The main characteristics of tungsten wire mesh are its high temperature resistance and high hardness, which makes it show unique advantages in some special printing applications. For example, in those printing processes that require high-temperature ink or special chemical treatment, tungsten wire mesh can maintain the stability of physical and chemical properties, thereby ensuring the smooth progress of the printing process.

- As a metal with a high melting point, tungsten wire mesh can still remain stable in a high temperature environment, which makes it used in the electronics or optoelectronics industry that requires high-temperature sintering or special heat treatment. Tungsten wire mesh is also suitable for processing certain printing materials with strong chemical corrosion due to its corrosion resistance.

3. **Principle of screen printing technology**:

- Screen printing is a printing technology based on the basic principle that the mesh holes of the pattern part of the screen are permeable to the slurry, and the mesh holes of the non-pattern part are not permeable to the slurry. The specific principle is: when printing, pour the slurry at one end of the screen, apply a certain pressure on the slurry part of the screen with a scraper, and move toward the other end of the screen at the same time, so that the slurry is squeezed from the mesh holes of the pattern part to the substrate by the scraper during movement.

4. **Application of screen printing technology**:

- The latex is removed at the openings of the screen pattern design, so that the slurry applied to the screen can be printed on the substrate through the openings of the pattern when the scraper brushes over the mesh.

In addition, when choosing the screen material, factors to consider include the type of printing material, the required accuracy, the printing environment (such as temperature, the presence of chemicals, etc.) and the cost. For example, the electronics industry, which requires extremely high accuracy, may prefer to use stainless steel screens, while in some situations that require special treatment, tungsten screens may be considered.
