Engraved Signs

When you talk about engraved signs and what materials are ideal for this marking method, what usually pops into your head is plastic and wood. These are indeed great materials to work with when it comes to engraving since these produce precise and crisp features on signs. These are not, however, the only materials that can be used when engraving is the marking method chosen for signs. There are a few other materials that will work just as well.

Some of the other materials that can work well with engraving machines are metal, glass, and stone. These are also great when engraved, and can be used in creating signs as well as plaques, nameplates and other engraved items. The engraving on these things may even be painted in to make these stand-out more.

But we are not talking about what materials are ideal for engraving. What we are trying to determine is what materials are not ideal for engraved signs and why. The answer actually lies in the kind of engraving that you are thinking of employing. There is the standard type of engraving that uses a diamond or metal cutter, and there is laser engraving, which uses laser light to cut through the material.

When you are to employ traditional engraving machines for the creation of engraved signs, you can engrave almost anything. From metals, to plastics, to wood – these engraving machines can engrave them, as long as these are of ample thickness. If an object is too thin however, it might be rather difficult for an engraving machine to effectively create the markings that you need.

When you want to use a laser engraver, you should be aware that while these can mark rather thin materials, there are some materials this engraver cannot be used on. This is because of the fact that when heat is used on some materials to mark them, fumes are created. Some of the fumes that are created can be rather toxic, and can endanger the people working on the item being engraved, hence the need to avoid such materials when it comes to laser engraving.

Some of the materials that cannot be engraved using lasers include polycarbonate or Lexan, due to toxic fumes; PVC due to the chlorine content; Vinyl due also to chlorine content; and carbon fiber. These are but a few of the materials that laser engraving is discouraged from being used. Any other material that contains chlorine is also discouraged.

While glass can be engraved, more and more manufacturers consider etching glass instead of engraving. This is because of the possibility of breakage when engraving is employed instead of etching. This is also because etching produces finer and crisper lines than engraving, when glass is the material of choice.
