How to determine the tension of the stretcher? The accuracy of screen printing is related to the accuracy of the screen printing plate, and the tension of the screen affects one of the important factors of the quality of the screen printing plate. The tension of the screen is related to the material and strength of the frame, the texture of the screen, the temperature, the humidity, and the method of stretching the net. Usually in the case of manual stretcher and without tension meter, the tension determination is mainly based on experience. When the net is stretched, the screen is stretched and the screen is pressed with a finger. Generally, the screen is pressed with a finger and the screen is felt. It has a certain flexibility. When using a stretcher and a large frame stretcher, the tension gauge is typically used to test the screen tension. When using a stretcher to stretch the net, since the movement of the stretcher chuck (tightening adjustment) is controlled by a barometer, the mesh of different textures has different air pressure values. Generally, the tension value of the tension net is 7-9kg/cm2: the tension value of the nylon mesh is 8-10kg/cm2: the tension value of the polyester mesh is 8-10kg/cm2; The net air pressure value is 10-13 kg/cm2. The above are the reference values ​​of the air pressure of several kinds of wire mesh stretching machines when stretching the net. The stretching net can refer to these data to stretch the net according to the actual situation to obtain the ideal stretch tension.
