1. In the printing process of Flat Screen Printing Machine ( https://www.hotairstenter.com/product/flat-screen-printing-machine.html ), bubbles appear on the pattern. The surface of the plastic head produces oil stains, stickiness and deterioration, and damage. The reason is that the center point of the glue head is just pressed on the pattern of this point. The ink has deteriorated. The ink is thinner (783 or 718). The scraper is not sharp. The curvature of the plastic head surface is insufficient. The ink is too thin. Add less additives to the ink.

2. The pattern lines of the flat screen printing machine are rough and fuzzy during printing. The surface of the plastic head is damaged. The ink is too thin. The steel plate pattern is damaged. The scraper is not sharp or notched. The pattern design is rough. The steel plate pattern is too deep. The ink is too dry.

3. During the printing process of flat screen printing machine, the pattern ink color is light and the ink is too thin. Ink precipitation. Add excessive amount of filler (generally controlled at about 5%). The steel pattern is worn. The depth of the steel plate pattern is insufficient.

4. In the printing process of the flat screen printing machine, the pattern of the steel plate appears to be excessive. Scraper notch. The rubber head slider is loose. The pressure of the glue head is too high.

5. During the printing process of the flat screen printing machine, the height of the deformed plastic head is insufficient. Improper selection of plastic head shape. The pattern is beyond the printing range. The glue head is too small and too hard. Plastic head pressure is too high

Maintenance and repair of automatic flat screen printing machine

1. Maintenance of automatic flat screen printing machine: Maintaining the flat screen printing machine can extend its service life and ensure that the flat screen printing machine maintains a good operating state and high printing accuracy.

2. The environmental requirements of the automatic flat screen printing machine: the production environment should be clean without excessive dust. The machine should be kept clean and covered with plastic bags to prevent dust during long-term shutdown.

3. The air source requirements of the automatic flat screen printing machine: the gas used for the flat screen printing machine should be clean and dry, and the water accumulated in the water separator of the water filter should be discharged regularly.

4. Ink: In the printing process, there will often be ink dripping onto the flat screen printing machine. These inks may penetrate into the active parts of the machine and solidify, causing difficulties in adjustment and even positioning inaccuracy. Therefore, this phenomenon should be immediately erased when printing.

5. Machine parts: After printing, the steel plate, rubber head, blade, oil bucket, oil roller, etc. should be cleaned for later use.

6. Lubrication: The sliding guides, bearings, rollers, and parts with mutual movements of flat screen printing machines need to be lubricated to make them move smoothly and reduce wear and prolong service life.

Precautions for the use of automatic flat screen printing machine The size of the steel plate should match the size of the oil pan, knife holder and oil roller. Attention should be paid to the choice of pad printing head: the hardness of pad printing paste can be divided into soft, medium and hard. For the finer patterns, the harder ones are used, and soft plastic heads are suitable for uneven prints. In addition, the volume and shape of the plastic head should be similar to the size of the pattern and the shape of the surface of the printed part. Use of Ink: Printed parts of different materials, such as plastic, glass or metal, must use different inks, and the ink must be stirred before being injected into the oil pan. When the operation is paused, press the "empty line" button to allow the oil scraping system to continue to work to prevent the ink from drying out. During the printing process of csgia.net, an appropriate amount of thinner should be added from time to time according to the air drying speed of the ink to maintain the proper viscosity of the ink. After the thinner is added, it should be stirred immediately. If the pad is stained with dirt, it must be wiped off with a cleaning agent . The fixture must be prefabricated according to the shape of the printed part. After printing, use a cleaning agent to clean the steel plate and remove the oil roller for cleaning. Safe operation, two people are not allowed to operate a machine at the same time, to avoid accidents.​​
