Precisely what are metal mesh screens? They are basically nets which might be employed in various applications including construction, utensils and fencing. By way of example, step into any kitchen these days and you are more likely to go to a metal mesh screen sitting on the counter, draining away the lake from wet dishes and silverware. Stainless steel’s corrosion resistance helps make the material highly amenable for this task.
But additionally you’ll see metal mesh screens employed in the screen printing industry. That usage will be the focus of this discussion. What will happen is often a rundown with the logic behind why you as a screen printer may wish to give serious consideration to some wire mesh screen constructed of metal.
First of all, quality lies at the reasons for these mesh screens for that screen printing industry. Screen printers who use wire screens created from stainless steel screen benefit from the highest amount of registration accuracy, precision treating their ink deposits and a superior amount of abrasion resistance.
Additionally, the mesh screens exhibit outstanding dimensional stability and narrow tolerance of thickness on the fabric being utilized inside the screen printing process. Consequently, printers experience more uniform and accurate aperture widths than previously.
It’s the strength with the material that these benefits are derived. Especially, the strong excellence of the steel provides for the usage of thinner wire diameters. Additionally, steel wicks away moisture, preventing it from being absorbed. It’s also generally capable to withstand both high and low temperatures along with humidity without difficulty. Indeed, applied temperatures all the way to 600°C (1112°F) can be remedied.
An additional of employing a stainless steel wire mesh screen is that it will keep its decoration. That is because the steel that it is made resists shrinkage, stretching and sagging. Consequently, the printer enjoys flawless screen printing each time, even after a lot of use.
Don’t let the assumed rigidity with the steel obstruct of giving wire mesh screens an attempt. They are actually more elastic than could possibly be expected yet they still spend the money for user the dimensional stability s/he is looking to get. This really is even in situations the place that the wire mesh is proscribed with an angle to the stencil frame.
That elasticity, actually, enables the screen printer to stretch a highly-tensioned, drum-tight screen and print with a minimum off-contact distance. The end result is maximum accuracy and also the most consistently printed product.
Finally, the wire employed in metal mesh screen has conductivity benefits because it doesn’t emit an electrostatic control of its own.
So now that most of metal wire mesh’s benefits have been outlined, of what screen printing capacities can the material go to best use? The high tensile strength and yield stress properties with the metal result in the mesh especially amenable to stencil printing.
Wire mesh can also be calendered for defined ink deposits. This calendaring process removes air pockets contained in all as-woven wire mesh. Therefore, it forces the wire knuckles to their final positions, causing a screen that is stabilized rapidly.
