The materials used in the production of the frame are mainly wood, hollow aluminum profiles, cast aluminum frames, steel and other materials. The most commonly used is the frame made of aluminum profiles. However, all kinds of net frames have their own characteristics. When selecting, the net frames of different materials can be selected according to different situations, which are introduced in turn.
The wooden frame has the characteristics of simple production, light weight, convenient operation, low price and simple stretching method. This frame is suitable for manual printing. However, the frame of the wooden material is poor in solvent resistance and water resistance, and is easily deformed after water immersion, which may affect printing accuracy. This kind of frame has been widely used in the past and is rarely used now.
The hollow aluminum profile frame and the cast aluminum frame are light in operation, high in frame strength, strong and not easily deformed, resistant to solvents and water, and beautiful. Suitable for mechanical printing and manual printing.
The steel mesh frame has the characteristics of firmness, high strength, good solvent resistance and water resistance, but it has the disadvantages of being cumbersome and inconvenient to operate, so the use range is small.
