Stenter Grid Selection Conditions

  • Stenter is a large-scale printing equipment widely used in the printing industry. Many people may not know the automatic screen printing machine. The net frame is a frame used to support printing. The net frame of the automatic screen printing machine is made of metal, wood or other materials. What are the selection conditions of the automatic screen printing machine? Let's take a look!
     
    The main materials for making the net frame of the automatic screen printing machine are wood, hollow aluminum profile, cast aluminum mold frame, steel and so on. The most widely used is the aluminum grid. However, various frameworks have their characteristics. When selecting, different data can be selected according to different situations. The following automatic screen printing machine grids are introduced in turn. The wooden net structure is characterized by simple production, light weight, convenient operation, low price, and simple way of fixing the net.

    The utility model is suitable for process printing, but the grid frame of this wooden material has poor solvent resistance and water resistance, and simple deformation after immersion in water will affect the printing accuracy. Such a grid used to be much used before, but now it is used less. The hollow aluminum profile screen frame and cast aluminum forming screen frame are easy to operate, the screen frame is high in strength, firm, not easy to be deformed, solvent resistance, good water performance, and beautiful. Suitable for mechanical printing and technical printing. The metal wire mesh frame has the characteristics of strong, high strength, solvent resistance, water resistance, etc., but the operation is cumbersome and inconvenient, and the scope of application is small.
    1. The net frame is one of the main materials for making screen printing plates. The selection of the sieve box directly affects the quality of plate making and printing. In order to meet the requirements of plate making and printing quality, the filter screen can be selected according to the following conditions;
    2. The joint surface of the net frame and the net frame should have a certain degree of roughness, so as to enhance the binding force of the net frame and the net frame;
    3. The grid frame must have a certain strength because when the grid frame is stretched, a certain tension and pressure need to be applied to the frame. This requires that the frame's voltage resistance is not deformed, and it must conform to the frame's dimensional accuracy;
    4. The reinforced screen frame is often in contact with water and solvents, and is affected by temperature changes during use. The screen frame needs to be kept not tilted to ensure repeated use. This can reduce waste and reduce costs;
    5. Flat Screen Printing Machine should be equipped with screen frames of different standards during production. When using the screen frame, it can be concluded that a suitable screen frame can reduce waste according to the size of the printing size, and the operation is simple.
