For quite a few labeling applications, metal stencils are an absolute necessity. Those stencils can be utilized for almost anything involving a label. For example you might need to label a chemical drum to warn the public of danger, or you could just need to print numbers on a sidewalk. Either way, metal stencils are the best way to go!
Metal stencils are built from quite a few different materials. The more common, generally being made by LPKF. It is vital to keep in mind that not every stencil comes out correctly the first time, which drives the need for an occasional rework station. Such stations can help the manufacturer to address any existing problems and get that stencil back on the right track. With any luck, those problems can be corrected permanently, but it is always a great idea to have a rework station available.
Right now there are two sorts of stencil fabrication. One is laser cut, and the latter is electroformed. First we will talk about laser cutting, which is a subtractive process. The stencil data is supplied via computer, and the information can be altered to alternate size if necessary. It should be noted that laser cut stencils do render ragged edges as a result of the vaporized metal being changed into slag throughout the cutting process. If you are looking for smoother walls, it would be best to look at microetching.
The additive procedure we spoke of is also referred to as electroforming. Nickel will be deposited inside an aperture, and photosensitive dry film laminated onto the foil. The flm will be polymerized with a UV right, using a negative image made on the mandril. The aperture will then be covered by a photoresist. In this process, the stencil could be grown using nickel plating around the photoresist. Though this technique might cost a bit more, but it should be well worth it considering it is done right on the first pass, rarely requiring any type of reworking.
Metal stencils are an amazing thing, and you should find that you can use them for a plethora of different applications. Guarantee you compare the different types, and decide what would work best for your project. Your plan will soon commence to take shape!
