What material is the screen frame of the automatic screen printing machine made of?

　　With the development of the printing industry, automatic screen printing machines have been widely used. Screen printing machines can perform color photo-level printing on the surface of different materials. The screen printing quality of screen printing has a great impact. Maybe many people don't know the screen frame of the screen printing machine, so what material is the screen frame of the screen printing machine made of?

　　The materials used to make screen frames mainly include wood, hollow aluminum profiles, cast aluminum forming frames, and steel. The most commonly used is the screen frame made of aluminum profiles. However, all kinds of screen frames have their own characteristics. When selecting, you can choose screen frames of different materials according to different situations, which will be introduced in turn below. The wooden screen frame has the characteristics of simple manufacture, light weight, convenient operation, low price, and convenient stretching method. This screen frame is suitable for hand printing. However, the screen frame of this wooden material has poor solvent resistance and water resistance, and is easily deformed after water immersion, which will affect the printing accuracy. This kind of screen frame was commonly used in the past, but it is rarely used now.

　　Hollow aluminum profile frame and cast aluminum frame have the characteristics of easy operation, high frame strength, firmness and not easy to deform, strong solvent and water resistance, and beautiful appearance. Suitable for mechanical printing and manual screen printing, etc. The steel screen frame has the characteristics of firmness, high strength, good solvent resistance and water resistance, but it has the disadvantages of being bulky and inconvenient to operate, so the scope of use is very small.

　　Conditions for selecting screen frames: Screen frames are one of the important materials for making screen printing plates. The selection of screen frames has a direct impact on the quality of plate making and printing quality. In order to ensure plate making, printing quality and other requirements, the screen frame can be selected according to the following conditions.

　　During use, the screen frame is often in contact with water and solvents, and is affected by temperature changes. This requires that the screen frame does not appear skewed, so as to ensure the repeated use of the screen frame. This reduces waste and reduces costs.
