Screen printing screen process squeegee plays a key role in creating pressure and handling ink in screen printing. Its hardness and shape, as well as the angle of squeegee, are a fundamental parameter that affects these effects.
Firstly, the cross-sectional shape of the squeegee is most commonly used as a pointed triangle and a rectangular rectangle is used as a flat printing tip triangle for screen printing. This is because the curved surface of the touch surface is a line-pointed triangle and it is easier to obtain ambition with less printing pressure. Ink. The undulations in the course of the rotation of the cylindrical product have also provided a good note for the application of the sharp-edged squeegee. Secondly, the hardness of the squeegee is also one of the parameters considered. Under all printing conditions, the softer squeegee has a lower pressure on the screen than the harder squeegee. The greater the pressure, the more invisible the ink will be printed.
The mesh distance in screen printing mesh is a unique variable in the screen printing process, which directly affects the handling effect of the ink. Too large and too small a mesh will have a negative impact on screen printing.
The line touch state of the cylindrical product after pressing under the wire mesh and the bus bar of the product determines that the mesh distance is smaller than that of the face screen printing. There is no fixed number here. The key is to be able to test the most suitable results. Screen Printing Machines There is no need to say that the printing of cylindrical products necessitates the selection of screen printing machines with curved surfaces. The difference between the screen printing curved screen printing machine and the flat screen printing machine is that the former screen performs a reciprocating plane motion during the printing process and the product rotates under the driving of the screen rack. Most of the curved screen printing machines fix the hollow plastic bottle on the rotating fixture with the transmission gear at the end. The parameters of this gear are very important, otherwise there will be problems in printing: we must make the diameter of the indexing circle and the hollow plastic The diameter of the bottle is flat so that the graphic on the screen will be accurately transported to the exterior of the plastic bottle during the printing process.
The above is an important description of the role of the process scraper. Screen printing meshs, in addition to the use of the process scraper, there will still be a long time when the screen is placed for a long time, more or less adhered to the dust before printing, if not cleaned in time, it will also cause paste.
