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 net frame has the characteristics of their respective ? when selecting ? can select different materials according to different situations of net frame ? are introduced below.Wooden screen frame has simple production, light weight, convenient operation, low stretch mesh method is simple in price.The net frame is suitable for the manual printing.But the wooden material net frame poor solvent resistance, resistance to water water easy to deformation after ? will affect the printing precision.The net frame before widely used ? is now rarely used.Hollow aluminum mesh frame and aluminum molding box ? ? net operation of the light box with high intensity, strong distortion ? the 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 water resistance, etc ? but there is bulky, inconvenient operation faults ? thus using range is very small.
Choose network frame's condition is what?
Net frame is one of the important material of making screen printing plate ? net box to select appropriate or not ? the process quality 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 net ? screen to screen frame have pull
Force and stress.This requires network box compression deformation ? ? does not produce to keep the box dimension precision.
(2) under the condition of guarantee strength as far as possible choose light weight ? ? net box is convenient for operation and use.
(3) screen frame and screen the roughness of bonding surface must have certain ? to strengthen screen and screen frame relay.
(4) net frame soundness.Net frame in use to often contact with water, solvent ? as well as affected by temperature change ? this request the phenomenon such as net frame not skewed ? to ensure the repeated use of net frame.This can reduce waste ? reduce costs.
In the production of (5) to configure different specifications of the net frame ? when used according to the size of the print size to determine the appropriate network box ? can waste less ? and easy operation.
What are the main specifications of aluminum alloy net frame?
By the known ? made of hollow aluminum wire net frame with light weight, stable size, appearance, easy to operate, etc.
