What exactly are metal mesh screens? They are basically nets which can be employed in many different applications including construction, utensils and fencing. As an example, get yourself into any kitchen nowadays and you are clearly likely to go to a metal mesh screen sitting out on the counter, draining away the water from wet dishes and silverware. Stainless steel’s corrosion resistance helps to make the material highly amenable to this task.
But more commonly you can see metal mesh screens employed in the screen printing industry. That usage could be the focus with this discussion. What follows is really a rundown of the main reasons why you like a screen printer may wish to give thinking into a wire mesh screen made out of metal.
First of all, quality lies with the reasons for these mesh screens for that screen printing industry. Screen printers using wire screens made of stainless steel screen enjoy the highest amount of registration accuracy, precision treatments for their ink deposits plus a superior amount of abrasion resistance.
Additionally, the mesh screens exhibit outstanding dimensional stability and narrow tolerance of thickness about the fabric used within the screen printing process. As a result, printers experience more uniform and accurate aperture widths than ever before.
It is the strength of the material where these benefits are derived. Specifically, the strong excellence of the steel provides for the application of thinner wire diameters. Additionally, steel wicks away moisture, preventing it from being absorbed. It’s also generally in a position to withstand both high and low temperatures and also humidity without difficulty. Indeed, applied temperatures as high as 600°C (1112°F) can be handled.
An additional of using a chrome steel wire mesh screen would it be will keep its decoration. The reason being that the steel where it’s made resists shrinkage, stretching and sagging. As a result, the printer enjoys flawless screen printing each time, even after numerous years of use.
Don’t let the assumed rigidity of the steel impede of giving wire mesh screens a go. They are actually more elastic than might be expected yet they still give the user the dimensional stability s/he is looking to get. This is even just in situations in which the wire mesh is fixed within an angle on the stencil frame.
That elasticity, the truth is, allows the screen printer to stretch a highly-tensioned, drum-tight screen and print which has a minimum off-contact distance. The end result is peak accuracy as well as the most consistently printed product.
Finally, the wire employed in metal mesh screen has conductivity benefits in that this doesn’t emit an electrostatic power over its very own.
Now that all metal wire mesh’s benefits have already been outlined, in what screen printing capacities can the material be placed to best use? Our prime tensile strength and yield stress properties of the metal make mesh especially amenable to stencil printing.
Wire mesh can be calendered for defined ink deposits. This calendaring process removes air pockets within all as-woven wire mesh. In turn, it forces the wire knuckles into their final positions, resulting in a screen that’s stabilized rapidly.
