Stenter ( https://www.hotairstenter.com/product/hot-air-stenter.html ) belongs to stencil printing, which is called the four printing methods together with lithographic, embossing, and gravure printing. Automatic screen printing machines include transcription, perforated pattern, spray and screen printing, etc. The principle of stencil printing is: the printing plate (the perforations that can pass ink are made on the base of the paper film plate or other plates). When printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the perforations of the stencil under a certain pressure. ) To form an image or text. The automatic screen printing machine is named according to the degree of automation of the screen printing machine. After several generations of industry personnel's wisdom and experience research, it is a development trend of screen printing machines after manual screen printing machines (handprinting stations) and semi-automatic screen printing machines. The use of more advanced technology and technology makes the screen printing process more accurate and faster. , Higher degree of automation.

The automatic screen printing machine is composed of five major elements, namely the screen printing plate, the squeegee, the ink, the printing table and the substrate. The working principle of the automatic screen printing machine is: use the screen printing plate to penetrate the ink through the graphic part of the screen, not the graphic The basic principle of partial mesh impermeability for printing.

When printing, pour ink on one end of the screen printing plate, and use a squeegee to apply a certain pressure on the ink position on the screen printing plate while moving toward the other end of the screen printing plate. The ink is squeezed onto the substrate by the squeegee from the mesh of the graphic part while moving. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, the squeegee is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the squeegee, due to the screen printing plate and the substrate. A certain gap is maintained between them, so that the screen printing plate during printing produces a reaction force against the squeegee through its own tension. This reaction force is called resilience.

Due to the effect of resilience, the Flat Screen Printer ( https://www.hotairstenter.com/product/flat-screen-printing-machine.html ) makes the screen printing plate and the substrate only have a moving line contact, while the other parts of the screen printing plate and the substrate are in a separate state. The ink and the screen are broken to ensure the dimensional accuracy of printing and avoid smearing the substrate. When the squeegee is scraped across the entire layout, it is lifted, and the screen printing plate is lifted at the same time, and the ink is gently scraped back to the initial position, so far is a printing stroke.
