In the early sixties, scientist discovered that they could use light sources for laser etching. By creating light source and focussing its energy they had a powerful tool that could shape an array of materials. These days, in the engraving industry, CO2 lasers are the tools of choice.
Lasers like many of today’s inventions came out of a laboratory. Almost all kinds of materials can be engraved by them. Sometimes it is also called etching, but etching requires masks and chemicals which lasers do not.
When one is looking for permanency or aesthetics in engraving, then marking is the preferred method. Etching uses reduced power and marks materials without cutting all the way through. A laser is ideal for cutting materials like acrylic (Plexiglas), PETG, thin polycarbonates (Mylar), styrene expanded PVC (Sintra), wood, paper and fabric. Engraving of graphite is also a clean process.
Etching leaves a permanent mark on an in-process or finishes product. Laser cutting can actually eliminate costs as it can easily cut through complex profiles without the need for additional operations.
Marking of glass while moving by CO2 lasers can prove to be a lucrative addition to industrial environments and applications for glass marking. Traditional methods like sand-blasting, ink pad printing and etching can be replaced while marking or etching glass and quartz. These will also help in reducing operating costs and costs of supplies.
For the purpose of laser marking, drawings can be easily converted into different formats like JPEG, Adobe-Illustrator, Corel Draw and AutoCAD amongst others. Marking services can be used on various applications from computer keyboards to special promotional gifts. As no inks are used, and its permanency and environment-friendly qualities make marking services popular for a variety of uses- n wedding giveaways, nametags, table nameplates, engraving of trophies etc.
Most jobs that are being carried out by conventional industrial engravers use this technique. Medical device industry, aerospace, manufacturing, automotive, pharmaceutical and electronic industries etc- all use laser machines and supporting systems.
The operating cost is minimal since there are no consumables. Even if the laser system becomes obsolete after many uses, it doesn’t require expensive clean-up or by-product disposal. Today laser engraving, cutting and marking is a viable and versatile technology that is being used by many engravers to improve productivity, add more available services to their customers and increase profits.
IPPL has been in the forefront of laser technology. They are situated in the heart of the Sydney Metro area and have been serving the community for many years. They specialize in the application of laser technology. They can engrave on any surface limited only by the bed of the laser. Typical applications include: custom signage, metal and plastic signs, metal and plastic tags, industrial signs and more.
