A1-A30 Model and Specification of Aluminum Frame for screen printing
Basic knowledge of screen printing screen frame
1. Net frame is made of what material?These materials have the characteristics of what?
Production network box materials used are mainly wood, hollow aluminum, cast aluminum molding box, several kinds of materials such as steel.The most commonly used is the aluminum production network box.But all kinds of screen frame has the characteristics of their respective, when selected, according to different situations, choose different material net frame, the following are introduced.
Wooden screen frame with simple, light weight, convenient operation, low price, easy tension net method etc.The net frame is suitable for the manual printing.But the wooden material net frame poor solvent resistance, water resistance, easy to deformation after water immersion, will affect the printing precision.This kind of screen frame in commonly used before, is now rarely used.
Hollow aluminum screen frame and aluminum molding net frame, has convenient operation, net frame with high intensity, strong is not easy to deformation, solvent resistance and water resistance is strong, beautiful, etc.Suitable for printing and manual printing machinery.
Steel net frame is solid, high strength and good solvent resistance and resistance to water, but there is bulky, inconvenient operation faults, so using range is very small.
2. Choose network frame’s condition is what?
Net frame is one of the important material of making screen printing plate, net box to select proper quality of plate making, and has a direct impact on printing quality.In order to ensure the quality of plate making, printing and other requirements can choose net frame according to the following conditions.
(1) net frame must have a certain strength.Because when stretched mesh, wire mesh have certain pulling force and pressure on net frame.This requires network box pressure, does not produce distortion, to keep the box dimension precision.
(2) under the condition of guarantee the strength, the net box choose light weight, easy to operate and use.
(3) screen frame and screen adhesive surface should have certain roughness, to strengthen the screen and screen frame relay.
(4) net frame soundness.Net frame in use to often contact with water, solvent, and is affected by temperature changes, which requires the net frame not skewed wait for a phenomenon, to ensure the repeated use of net frame.This can reduce waste, reduce the cost.
(5) to configure different specifications in production network box, when used according to the size of the print size to determine the appropriate network box, less waste, and easy operation.
3. What are the main specifications of aluminum alloy net frame?
From the foregoing, made of hollow aluminum wire net frame with light weight, stable size, appearance, easy to operate, etc.
