The screen printing machine uses the principle of screen holes to press the ink down from the screen, causing the screen to deform, thereby squeezing out the ink to form a print. The specific steps include: first, install the screen on the printing head and tighten the screen; then, transfer the ink in the ink pump to the screen through the conveyor belt; finally, raise the printing head to the printing position for printing. During this process, the squeegee squeezes the ink and the screen printing plate during movement to form a pressing line, and the ink leaks through the mesh holes onto the substrate, completing the printing cycle.

There are many types of screen printing machines, which can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, electrostatic screen printing machines, etc. according to different standards. Each type of printing machine has its own characteristics and is suitable for different printing needs.

-Flat screen printing machine : Suitable for flat substrates, such as paper, wood boards, etc. During printing, the printing plate is fixed and the squeegee moves horizontally.

-Curved screen printing machine : Can print on curved substrates (such as spheres and cylinders). During printing, the squeegee is fixed, the printing plate moves horizontally, and the substrate rotates with the printing plate.

-Rotary screen printing machine : Uses a cylindrical screen plate with a fixed squeegee inside the cylinder. The printing plate and substrate move synchronously at the same linear speed, which is suitable for continuous printing.

-Electrostatic screen printing machine : Uses electrostatic attraction to transfer ink from the screen printing plate to the printing surface. It is a non-contact printing method, especially suitable for high-temperature substrates.

Screen printing machines are widely used in many fields due to their unique advantages:

1.‌ Efficiency ‌: ‌ Modern screen printing machines adopt automation technology, ‌ can achieve 24-hour uninterrupted printing, ‌ significantly improve production efficiency.

2.Accuracy : High-precision plate making and printing technology ensures the clarity and consistency of patterns and text, meeting the requirements for high-quality printing.

3.Diversity : Screen printing is suitable for substrates of a variety of materials and shapes, including paper, plastic, metal, glass, ceramics, etc., and has wide applicability.

4.Stability : The automatic screen printing machine equipment operates stably and reliably, and can maintain efficient working status for a long time, reducing the risk of equipment failure and production interruption.

5.‌Intelligent‌ : ‌The intelligent control system and human-machine interface are easy to operate, ‌can quickly adjust and set parameters according to different printing needs, and ‌achieve diversified printing. ‌

Screen printing machines have shown strong adaptability in many fields, including but not limited to:

-Packaging and printing : Widely used in packaging and printing of food, medicine, cosmetics and other products to enhance product added value.

-Textile printing : Printing patterns or texts on textiles to enhance product grade and added value.

-Electronics industry : In the manufacturing process of circuit boards, electronic components and other products, fast and accurate precision pattern printing can be achieved.

-Automobile manufacturing : Used in body painting, interior decoration and other aspects to complete large-area, high-precision printing.

-Advertising industry : Meet the needs of enterprises for efficient and precise production of large-scale outdoor advertisements and small promotional posters.

With the continuous advancement of science and technology, screen printing equipment will develop in the direction of being more efficient, smarter and more environmentally friendly. High-precision, intelligent and integrated solutions will become the main trend in the future. In addition, the promotion of green environmental protection concepts will also prompt screen printing machines to pay more attention to environmental protection and energy saving during the use of ink and printing process, reducing the impact on the environment.

In summary, screen printing machines play an important role in the printing industry with their high efficiency, precision, diversity and stability. With the continuous development of technology and the continuous expansion of application fields, screen printing machines will continue to lead the printing industry towards a more efficient, smarter and more sustainable direction.
