Screen Frame Selection:
According to the material, the screen frames include wood frame, aluminum frame, iron frame, plastic frame, stainless steel frame, copper frame, commonly used wood frame, aluminum frame, iron frame, etc.
- Wooden frame: cheap and easy to make, it can be stretched manually and mechanically, but its disadvantage is low strength and easy to deform, it is only suitable for the printing of low precision products, and not suitable for rapid and high precision screen printing, in addition, the wooden frame out of Netease Slack, poor recycling.
- Iron Frame: compared with wood frame has the characteristics of stable size, strong and durable, but its weight, easy to rust, less convenient to use, and can only use mechanical tension net.
- Aluminum frame: Although only applicable to mechanical tension and Mesh, but its deformation is small, light, not easy to rust, easy to move, so the aluminum frame is currently the most used in the printing plate screen frame.
Screen Mesh Stretch
When making a screen plate, the method of stretch includes three types: manual, mechanical, and pneumatic. If the screen printing factory does not require high accuracy, it can generally adopt the first two methods; if the requirement is higher, it can use the last type of pneumatic stretch machine. The pneumatic stretch machine is suitable for high accuracy screen-mesh making purpose. It has the advantages of uniform pulling force, convenient use, and it can meet different requirements of pulling screen tension, which is especially suitable for stretching the screen mesh of high-precision color registration printing.
