Exactly what are metal mesh screens? They’re basically nets which might be used in a variety of applications including construction, utensils and fencing. For instance, walk into any kitchen nowadays and you’re simply likely to visit a metal mesh screen sitting out on the counter, draining away water from wet dishes and silverware. Stainless steel’s corrosion resistance makes the material highly amenable to this task.
But typically you will see metal mesh screens used in the screen printing industry. That usage could be the focus of the discussion. Below is often a rundown with the explanations why you as a screen printer would want to give serious consideration to some wire mesh screen made out of metal.
First of all, quality lies on the first step toward these mesh screens for the screen printing industry. Screen printers using wire screens made from stainless steel wire mesh enjoy the highest level of registration accuracy, precision treating their ink deposits and a superior level of abrasion resistance.
Additionally, the mesh screens exhibit outstanding dimensional stability and narrow tolerance of thickness about the fabric used in the screen printing process. Because of this, printers experience more uniform and accurate aperture widths than previously.
It’s the strength with the material where these benefits are derived. Especially, the strong expertise of the steel permits the usage of thinner wire diameters. Additionally, steel wicks away moisture, preventing it from being absorbed. It also is generally in a position to withstand both high and low temperatures and also humidity easily. Indeed, applied temperatures all the way to 600°C (1112°F) can be treated.
Another benefit utilizing a chrome steel wire mesh screen is it will maintain its shape and size. That is because the steel where it can be made resists shrinkage, stretching and sagging. Because of this, the printer enjoys flawless screen printing whenever, even with many years of use.
Do not let the assumed rigidity with the steel obstruct of giving wire mesh screens a shot. They’re actually more elastic than might be expected yet they still give the user the dimensional stability s/he needs. This really is even just in situations in which the wire mesh has limitations within an angle for the stencil frame.
That elasticity, in reality, allows the screen printer to stretch a highly-tensioned, drum-tight screen and print with a minimum off-contact distance. Fundamentally maximum accuracy and also the most consistently printed end result.
Finally, the wire used in metal mesh screen has conductivity benefits in this it does not emit an electrostatic charge of its very own.
Now that all metal wire mesh’s benefits have already been outlined, in what screen printing capacities can the fabric go to best use? The top tensile strength and yield stress properties with the metal make mesh especially amenable to stencil printing.
Wire mesh can be calendered for defined ink deposits. This calendaring process removes air pockets contained in all as-woven wire mesh. Subsequently, it forces the wire knuckles to their final positions, resulting in a screen which is stabilized in a short time.
