How to control the pressure generated during the use of a screen printing machine?
Time of publication:2023-5-6

Dongguan screen printing machines are mainly used in the electronic processing industry, for screen printing logos on printed circuit boards, logos on instrument casing panels, and solder paste printing during circuit board processing. How to control the pressure generated during the use of a screen printing machine?

The effect of printing pressure on a screen printing machine is to ensure that the screen is in full contact with the printing surface, and the smaller the pressure, the better. Due to the greater pressure, although the scraper has a good contact with the screen, the flattening degree of the screen and the degree of the scraper’s insertion into the mesh are higher. Therefore, the amount of ink transfer is smaller, and the deformation of the scraper is also greater. This will have a significant impact on the oil filling situation and increase the deformation of the screen. Moreover, the conflict force between the scraper and the screen will also increase, which not only increases the conflict with the screen, but also affects the scraping speed of printing.

During the screen printing process, the scraper and the screen plate are touched horizontally and subjected to pressure, so the scraper will inevitably wear out after a certain number of uses. In addition, collision is inevitable during use, resulting in scratches on the scraper. When the scraper wears out, it will affect the printing effect; Therefore, before printing, it is necessary to check the flatness, sharpness, and defects of the scraper blade edge.

After the scraper is worn out, it needs to be ground before use. Grinding can be divided into manual grinding and mechanical grinding. Generally speaking, during manual grinding, the angle and pressure of the scraper may affect the grinding effect. To ensure the straightness of the blade, sandpaper can be applied to a flat wooden board and a wall panel perpendicular to the grinding board can be erected along the grinding direction. The scraper quality of mechanical grinding is uniform and stable, better than manual grinding. In practical production, the scrapers after grinding should also be inspected.
