Laser Engraving- Finds Applications in Various Industries!

In a growing number of industries, laser etching and Laser Engraving services are becoming more and more important. There are many reasons to use these services in industries, some basic reasons for the same are:
Not only extremely durable, this mark is permanent and cannot be removed in most cases without destroying the product itself, this is true for laser etching, laser marking or laser annealing.

Besides offering clear sharp results, the laser marking process is accurate, 100% repeatable, and fast.
Without any machine change over, and, without replacing any tools, the laser mark or laser etch can quickly and easily be changed. A simple drag and click computer operation is the changing of a laser marking or laser etch.

No consumables and no additional purchases of added materials or supplies is required in the laser. Therefore virtually non existent are the operating and maintenance costs of owning and running the laser marking or laser etching system.

Basics of Laser For light amplification by simulated emission of radiation, the word laser is an acronym. With a laser gas, electrode set, and electrical discharge, the laser beam is formed in a sealed tube. As the beam exits the laser tube up to 7mm to 14 mm for most laser etching and laser marking operations, the beam is emitted into a telescope which expands the laser beam from a size of approximately 2mm. Containing two mirrors located on high speed galvo motors, the expanded beam is directed into a laser head. Though a single element flat field lens to the product being laser marked or etched, the laser beam is directed off the mirrors.

In size from 65mm x 65mm [2.5" x 2.5"] at the smallest size to 356mm x 356mm [14.0" x14.0"] square at the largest, typically the laser marking or laser etching fields created range. The laser beam spot size is the next consideration. At the laser marking or laser etching point on the product, this is the size of the focused laser light energy and can vary from to approximately 540 microns or .021" for Co2 lasers to approximately 200 micron [micrometers] or .0078" at the smallest. From approximately 20 microns or .0007" at the smallest to approximately 70 microns or .0027" at the largest for Nd:YAG lasers, the laser beam spot size ranges. Typical of the laser marking or laser etching process, these small spot sizes and highly focused laser light energy creates a detailed, clear, permanent marking.

Controlling Laser Marking and Lasers Options
Using a software, laser etchers and laser markers are controlled. Variables that are needed to be controlled are:

1. Laser power – It is measured in terms of watts

2. Frequency, refers to the frequency of pulse of the laser beam

3. Inches per second, refers to the speed with which the beam steering mirrors are moving.

Laser Marking- Carving Aesthetic Marking on Variety of Objects!

For making permanent, precise, aesthetic markings on objects, laser technology has long been the preferred tool. Laser leaves its mark everywhere, from the patterns on your kitchenware to the patterns that can be carved on your stained-glass windows. Instead of doing it by hand or other forms of radiation the reason why people choose laser marking over methods is:

1. Speed. At a fast pace, this laser marking technology works. Design can be reproduced in a matter of seconds, by programming a design into a laser machine. A hundred times that duration would be required by the same thing, by a human hand.

2. Repeatability. All security information like watermarks, logos, barcodes etc, and producing perfect replicas is of the greatest importance here. With levels of error too low for even the most sophisticated machines to detect, laser replication is as error-free as it gets. Also, even when it is not of such paramount importance, repeatability is often desirable - for example, while printing designs on apparel or accessories in bulk.

3. Precision. Than a few microns, a laser beam is no thicker. A thousandth of a millimeter is a micron. Therefore, for making fine markings on areas where precision is absolutely necessary, there is no better instrument than laser. This is why on things like medical implements, glassware, barcodes, backlit keyboards etc laser is used.

Till recently, however, to 2-dimensional surfaces, laser instruments have been limited. Its precision, repeatability, speed, and permanence, even this was not seen as too great as limitation, as the main advantages of laser. Now, to include 3D items, of the most complex shapes and varied sizes, the same precise performance has been diversified. This is where several features of 6-axis laser comes in. 6-axis laser technology combines:

# To move around the work piece, use of robots. Both the head and the material being worked on are moved around to generate optimal results as this allows a more constant path and distance of the laser.

# 3D scanning

# With vision system, marking lasers

# Even around complex and elaborate 3D shapes, software tools to allow image wrapping, such as vases, lanterns, gems and so on

Consequently, in industries that require etching, high-precision cutting, or marking on 3D surfaces, 6-axis lasers marking services have become highly popular. As most people know by now, as often as they are made by painting, markings these days are made by erasure. By having paint on the entire surface, backlit keyboards, for example, work, but to create the symbol on the key, a few layers of paint removed. For car dashboards etc, the same holds true.

In the aeronautical industry too, 6-axis lasers are being used, to remove the paint from magnesium castings. To remove metal plating from surfaces, another important use of this state-of-the-art, sophisticated, this marking technology is to generate beautiful, complex patterns.

Plastic Card Printers should be chosen with great care!

Diverse plastic card printing companies offer their services for the printing of cards, as these cards are commonly used by everyone, and in the market or on the internet, it can be located easily.

For the printing of cards, diverse companies have different terms and conditions. To ensure quality, a card printing company must be carefully selected. For choosing the right card company, some tips are mentioned below:

• To ensure quality plastic cards for your company, always check the history and success rate of the company. The best option to go for is a company having a good reputation and sound background in the printing. It is important to make sure that the company you are choosing is not one of those companies that unfortunately grab money and run away.

• Your business can suffer harm when choosing a company on the basis of low cost. It is important to look for quality rather than the cost. Sometimes companies don't deliver timely results and also reduce the printing quality that offers low priced packages.

• For making the process of selection easier for the client, the company you choose should have a product catalogue. Since an outdated card is not of much help in promotion of a company's business, the designs offered by the company must be updated and trendy.

• Environment friendly printing of the cards must be provided in the company you choose. Those materials that cannot get recycled and can damage the environment it should avoid using.
Similarly following things should be included in the card itself:
• Logo and objective of a company:

The objective and logo of the company must be included in the card.
• Design

For the client, card design must be eye catching and trendy. One must avoid over crowded designs in a card.
• Ink Quality
Good quality Ink must be used for the card printing. To ensure a long life for the card, it should not get lighter with the passage of time.

• Using Technology and Bar codes

These days for example face book, twitter, Linked In, Google+ etc, usage of bar codes like URL addresses as well as QR Codes of the social networking sites on the card is very common. Therefore to give an updated look to the card, a company must make sure to include these details on the card.
For someone who is looking to choose the right kind of plastic card printing company, the above mentioned tips can be of great help.

The printing of the card should not be taken for granted as a quality and professional plastic card can enhance the awareness of the company's business in a very efficient way.
By selecting a proper and well reputed Plastic Cards Printers company, the quality of a card can only be ensured.
