The structure adopts aluminum girder and dual rail, with the imported aluminum clamp, to assure the high tension during meshing, and it is easy to expand and contract, to suit different size of screen printing plate during meshing.Easy operation, even stretching tension during meshing, the stretching area can be adjusted, we can process many printing plates in the same time, which enhance the efficiency.The screen mesh will not rubbed with the screen frame during meshing, which can lessen breakage, improve economic returns.Mainly applied to the industries of SWT Mask Laser、PCB、Bid board、EL&LCD manufacturing、membrane switch etc. The general features of these industries are: large quantities of stretching net、high stretching tension、high precision etc.
