How to determine tension when stretching bolting cloth

Stretching bolting cloth (screen printing mesh) is quite important for printing accuracy. So how should we determine the tension when Stretching bolting cloth in order to make the best use of bolting cloth (screen printing mesh)? Let’s find out in this passage.

Screen printing accuracy is related to the accuracy of screen printing, and screen tension affects one of the important factors of screen printing quality. 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 no tension meter, the tension determination is mainly based on experience. When stretching the net, the net is stretched and the screen is pressed with a finger. Generally, the screen is pressed with a finger, and the net is felt. It will be flexible.

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 pressure value is 10-13kg/cm2.

The above are the reference values of the air pressure of several kinds of screens in the stretched net. The stretch net can refer to these data to stretch the net according to the actual situation to obtain the ideal stretch tension.

Hope the passage is of great help for you when determining the tension for stretching bolting cloth.
