1. Wooden screen frame

Wooden screen frame has simple production, light weight, easy to operate.Low price, stretch network method simple characteristics, this screen frame is still widely used in manual printing, especially small surface printing.But the wood material solvent resistance, poor water resistance, easy to deformation after water immersion, will affect the printing accuracy.There is a tendency to be gradually replaced by metal mesh frames.At present, it is mainly used in manual screen printing.

Wooden ark is the square frame that surrounds with skill bar, 4 horn are fixed union.The size of the square bar depends on the size of the frame.The size is generally between 3cmX3cm and 4cmX5cm.Mesh frame four corners of the combination of a variety of ways, such as flat, overlapping.In the process of combining,

L – shaped metal devices on the four corners can prevent or reduce the deformation of the mesh frame.

Wooden frame has a variety of types, some wooden frame without groove, directly coated with adhesive, stretching network;Some wooden frames with grooves, with wedges fixed screen;There are also adjustable bars or metal bars in the wooden frame, its thickness is the same as the frame, the adjustment nut protruded through the fixed frame, just tighten the butterfly nut, the screen can be tightened.

2. Aluminum mesh frame

The screen frame of aluminum alloy material has the characteristics of light operation, high strength, not easy to deform, not easy to rust, easy to process, solvent resistance and water resistance, beautiful and so on.The screen frame is mainly formed by welding various aluminum tubes.The aluminum alloy tube is hollow, the section shape of the tube has many kinds, the section shape of the screen frame of the hollow aluminum profile commonly used in China is square, rectangle.The wall thickness is 1.5mm, 2.0mm and 2.5mm.

3. Steel mesh frame

Steel mesh frame has the advantages of firm, high strength, good water absorption and solvent resistance.But it is bulky and inconvenient to carry, so it is used less.

4. Plastic mesh frames

Plastic mesh frame is still under development, thermoplastic, strong polyester and fiberglass materials.The frame bar of the thermoplastic frame is made of composite material, the outer tube is plastic and the inner core is wood.Plastic has thermoplastic energy, can be used to wire mesh bonding on it;The wood core ensures the strength of the screen frame.

5. Combine screen frames

This is a strong polyester or fiberglass frame as a free combination of the frame.Both materials are very strong;The Angle of the frame is connected by special Angle fasteners, which is very simple to assemble and disassemble.Such as the use of glass fiber frame edge, nylon embedded corner of the combined mesh frame, strong, anti-static, thick fiber can prevent the erosion of the printing solvent.Before drawing net, need sandpaper to grind next face, make it easy to stick.In addition, because the mesh frame is the combination of activities, after use, may have to be taken apart and reassembled, so when the adhesive mesh glue to be particularly careful, in order to avoid through the Angle, hinder the removal of the mesh frame.
