What are the categories of Screen Printing Machine?

 Screen Printing Machine is classified:

①Flat Screen Printing Machine. It uses a flat-screen plate to print on a flat substrate. Generally, the squeegee moves horizontally against the plate, and the substrate is replaced by the rise and fall of the plate.

② Curved Screen Printing Machine. The use of flat-screen in the round surface substrate printing, generally squeegee plate fixed, the printing plate horizontal movement, the substrate with the printing plate, and other linear speed rotation.

③Rotary Screen Printing Machine. The use of cylindrical screen plate, cylinder internal

The printing plate rotates and the substrate moves at the same linear speed.

④Electrostatic Screen Printing Machine. It uses a stainless steel screen plate with good electrical conductivity, and the electrostatic force between the positive and negative electrode plates drives the powder and ink through the through-hole part of the plate to the surface of the substrate, which is pressureless printing. The shape of the machine varies depending on the substrate, but generally includes the substrate input part, printing part, ink fixation drying part, and substrate collection part. The printing part consists of a screen printing plate, electrode plate, high-pressure generation device. 5.

5. Electrostatic screen printing: electrostatic screen printing is the use of electrostatic gravitational force to transfer the ink from the screen printing layout to the substrate surface method, which is a non-contact printing method, is to use a conductive metal screen as a printing plate, and high-voltage power supply connected to the positive pole; the negative pole is a metal plate parallel to the printing plate; substrate between the two levels. Printing, the printing plate toner through the mesh with a positive charge, and by the negative charge of the attraction, scattered to the substrate surface, and then heated and other methods to set the image to form a print. This method is now mainly used for high-temperature substrates, such as the printing of steel plates out of the furnace.
