What You Must Know About Laser Engraving

For the engraving industry, CO2 lasers, named for the gasses used to create the light source, are the tools of choice. There are a variety of advantages to using a laser over other methods of engraving; first of all, because the tool is a beam of light, there is no product contact, which translates into less chance of product damage or deformation. It didn't take long for the engraving industry to notice lasers and soon they were being used for a wide variety of industrial applications including welding, heat-treating, etching and engraving.

It was in the early 1960's when scientists first discovered, that they could create a light source, focus the energy and have a tool powerful enough to affect certain materials. The name of the light source - LASER, is an acronym for Light Amplification by Stimulated Emission of Radiation. Sometimes laser marking is referred to as laser etching; unlike conventional etching, laser etching needs no masks or chemicals.

Laser etching is basically just another name for laser engraving. Almost all materials can be laser engraved/laser marked.

A laser works well for cutting acrylic (Plexiglas), PETG, thin polycarbonates (Mylar), styrene expanded PVC (Sintra), wood, paper and fabric. Laser etching provides a permanent message on an in-process or finished component. Laser cutting adds high precision, reduced contamination or warping, and a quality finish to industrial cutting applications.

Laser etching is the process of marking the material without cutting all the way through using reduced power. It can be done on many materials including slate, granite, stainless steel, leather, arborite, glass, mirrors, and premium hard woods.

Laser marking is also favored when the part to be marked is too small or has too complex a shape to be marked with anything but etching. Laser marking services can be used for many thousands of applications from computer keyboards to special promotional gifts. Some of the items that Co2 lasers and Co2 laser systems can be utilized for regarding marking and etching glass or quartz are float glass plants, manufacturing of glass doors and windows, permanent serial numbering, ANSI safety information, customer logos, decorative or specialty glass manufacturing, manufacturing data related to plant, production date and line, and/or part numbers.

Laser marking of glass by Co2 lasers on the fly or while moving can be an excellent addition for many industrial environments and applications for glass marking. It's flexible, programmable and environmentally clean. Co2 lasers can provide excellent results for marking glass and also provide significant reductions in operating costs and cost of supplies.

There are no consumables so operating costs are minimal, and the laser system, if properly exhausted, runs clean, so that costly cleanup or by product disposal is unnecessary. Laser engraving metal uses the most power especially if the metal is of the harder type.

Of the many items being laser engraved today, iPods and laptops rank among the highest in the consumer marketplace. Also these engraving services are available in most specialty stores because it's now the most common type of engraving. Laser machines and systems are used in a variety of applications and industries including medical device, aerospace, manufacturing, automotive, pharmaceutical, and electronic.

Laser Cutting Tools

There are various laser cutting tools depending on the type of finished product that you prefer.

Laser cutter routers that are computer-driven can cut each letter precisely, capturing every detail of the selected style. The said manufacturing systems are useful in cutting out symbols and logos in a cost effective manner.

Laser that is in a solid state uses one crystal rod with flat and parallel ends. Both ends have surfaces that have the ability to reflect. A light source that has high density and a flash tube surrounds the crystal.

When power is given by the network of pulse-forming, an intense light pulse called photon is released in one of the rod crystals. The light released is one wavelength and allows for minimum divergence.

A hundred percent of laser light is reflected on the rear mirror while thirty to fifty percent will pass through the mirror then to the shutter assembly to the angled mirror before going down through the lens and then to the work piece.

The laser light beam is not only coherent but also has high energy content. When it is focused on the surface, the laser light creates heat used for welding, drilling, and cutting.

The laser beam and the work piece is manipulated through the use of robotics. It can be adjusted to different sizes and heat intensity. The smaller laser is used for drilling, cutting, and welding while the larger machines are used in off giving heat.

One of the advantages of laser cutting is that cutting lubricants are no longer required. Also, this procedure boasts of very fine width of cut and thermal input with a narrow zone affected by heating.

So choose from various types of laser cutting tools to give you the results that you want.
