Casual Articles - Understanding Laser Marking and Laser Etching Systems
Our doctors and therapists warn that stress is the cause of many illnesses and reduces the quality of sleep, relationships and well being. Yet, how can you reduce stress without shirking your duties and responsibilities? Everyone dreams of running away to a French chateau as they are driving the carpool in heavy traffic. However, usually we do not need to change our lives drastically to make substantial improvements to our health and happiness. Here are six steps for type A personalities and overworked moms to use to reduce stress in their minds and their lives.1. Remember when you were eight years old? What did you think you would be doing when you grew up? Were you a fireman? Visit a firehouse and ask if they need a hand. Were you a ballerina? Enroll in an
2. Laser marking produces a surface mark with very little engraving and very little disruption of the material surface. This is especially useful in certain industries such as discrete electric components, semi-conductor, electrical fuse, and ceramics where laser etching can actually damage part or change the conductive qualities of the part.

The heart of the market is trading and there’re many principles and dogmas on the basis of which trading is performed. This article will consider the question about the essential ideas of the market participants and their theory of the trading. Market ideologies are essentially beliefs about how we should measure the value of capital. They help traders to determine the relative worthiness of different stocks. They define certain factors as more important than others to consider when figuring out which stocks to buy and which to sell, in what amounts, and at what price. And they provide a theory to explain why and when stock prices vary as they do. The theory, of course, may not be objectively accurate. Stock market participants are not empowered with any special abi
• The mark is extremely durable, permanent and in most cases cannot be removed without destroying the product itself, this is true for laser marking, laser etching, or laser annealing.
• The laser marking process is accurate, 100% repeatable, fast, with very clear sharp results.
• The laser mark or laser etch can quickly and easily be changed without any machine change over, and, without replacing any tools. The changing of a laser marking or laser etch is a simple drag and click computer operation.
• The laser requires no consumables and no additional purchases of added materials or supplies. Therefore the operating and maintenance costs of owning and running the laser marking or laser etching system are virtually non existent.
Laser Basics
The word laser is an acronym for light amplification by simulated emission of radiation. The laser beam is formed in a sealed tube with an electrode set, laser gas, and electrical discharge. The beam is emitted into a telescope which expands the laser beam from a size of approximately 2mm as the beam exits the laser tube up to 7mm to 14 mm for most laser marking or laser etching operations. The expanded beam is directed into a laser head containing two mirrors located on high speed galvo motors. The laser beam is directed off the mirrors though a single element flat field lens to the product being laser marked or etched.
Typically the laser marking or laser etching fields created range 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. The next consideration is the laser beam spot size. This is the size of the focused laser light energy at the laser marking or laser etching point on the product and can vary from approximately 200 micron [micrometers] or .0078” at the smallest to approximately 540 microns or .021” for Co2 lasers. The laser beam spot size ranges from approximately 20 microns or .0007” at the smallest to approximately 70 microns or .0027” at the largest for Nd:YAG lasers. These small spot sizes and highly focused laser light energy create the detailed, clear, permanent marking that is typical of the laser marking or laser etching process.
Controlling Lasers and Laser Marking Options
Laser markers and laser etchers are controlled via software. Several variables need to be controlled:
1. Laser power as measured in watts
2. Frequency, meaning the pulse frequency of the laser beam
3. Inches per second, meaning the speed that the beam steering mirrors are moving
Determining the correct setting for the laser is the single most important and critical element in the success or failure of the laser marking process. Once the proper settings have been determined and demonstrated a 100% repeatable laser mark can be achieved.
Laser controller software is accessed via a PCI interface card. This sends the digital signals of the computer based marking or etching files to the motors and directs the laser beam to the product being laser marked or laser etched.
There are several different types of laser marking and laser etching and several different considerations in terms of visual results for the laser mark or laser etch.
1. Laser etching produces a visible etching or depression into the material. Laser etching replaces traditional process like mechanical press or pin scribing. Laser etching can be done with either a Co2 or YAG laser on virtually any material surface and to any depth from very light etching to very deep etching. For example, laser etching is used to engrave serial numbers into metal gun frames. Generally speaking with laser etching the material being laser etched is vaporized at the laser etching point due to the typically high power densities of the laser beam at the point of laser etching.
2. Laser marking produces a surface mark with very little engraving and very little disruption of the material surface. This is especially useful in certain industries such as discrete electric components, semi-conductor, electrical fuse, and ceramics where laser etching can actually damage part or change the conductive qualities of the part.

Motivational humorous speakers can help to motivate meeting attendees at your next event. Motivation has been defined as the deployment of physical, mental and emotional energy toward a specific task or goal. In pure psychological terms motivation is often referred to initiation, intensity and persistence of a specific behavior and by employing a motivational humorous speaker you can tap into true motivation. Motivation can be a temporal and dynamic state that should not be confused with emotion or personality. A motivational humorous speaker can help point out that motivation is having the desire and willingness to do something. A motivated person can be reaching for a long-term goal such as becoming a professional athlete or a more short-term goal like learning h

A supply chain, logistics network, or supply network is a coordinated system of organizations, people, activities, information and resources involved in moving a product or service in physical or virtual manner from supplier to customer. Its management deals with the process of planning, implementing, and controlling its operations with the purpose of satisfying customer requirements as efficiently as possible.Supply chain management spans all movement and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. It integrates supply and demand management within and across companies.If a supply chain management system is properly implemented, strategic and competitive areas can be used to the

Any modern business requires the printing of labels, be it a retailer printing labels on products for sale, a logistics company printing labels to track shipments, or a manufacturer printing labels on goods produced. Small businesses and homes also find label printers handy if there is a lot of mailing to be done. There are also federal legislations that require the printing of labels in a specified manner. It is because of these and many other reasons that labels have become an invariable part of everyday business.Good label printers are thus required to print labels. With the increasing need of label printing, label printers have evolved from the simple label printers of yesteryear to the highly specialized label printers like bar code label printers and e

How a Simple Packaging Product Can Greatly Enhance Your BusinessModern manufacturers are under more pressure than ever to make their operation run smoothly, efficiently and economically. An increase in the number of competitors, higher supply prices, and a growing emphasis on cost cutting have all led manufacturers to seek new, ingenious methods to increase the productivity and profitability of their business.One such method is lean manufacturing, a revolutionary business philosophy that focuses on enhancing product quality, cutting costs, executing more efficient delivery methods, and employing personnel in the most productive manner possible so as to maximize profitability and performance. Industry giants like Toyota and General Electric have
2. Laser marking produces a surface mark with very little engraving and very little disruption of the material surface. This is especially useful in certain industries such as discrete electric components, semi-conductor, electrical fuse, and ceramics where laser etching can actually damage part or change the conductive qualities of the part. Generally in order to produce the laser mark without deep engraving a high speed per inch setting for the galvo head is used.
3. Laser etching and laser marking generally do not produce any color changes and create a colorless impression. There are exceptions as certain plastics will sometimes react to and change color under either Co2 or YAG laser light. Also, in some cases, additives can be incorporate into the materials being laser marked or laser etched in order to produce a color change. Another exception occurs when the wavelength of either the Co2 or YAG laser is changed from those typically used in laser etching and laser marking. This can produce a color change after laser etching on some materials.
4. Laser annealing is another popular form of laser marking. This type of laser marking is generally undertaken with a YAG laser on metal surfaces using lower power, high frequency and slow writing speeds to produce heat on the surface of the product. Laser annealing can be used to replace electro chemical etching and ink marking as the laser annealing process creates a black mark with no etching. Care must be used, as the heat generated can cause iron in some metals to be pulled to the surface, and rust can result if the parts are subjected to sterilization after laser annealing. This can be an especially difficult issue for medical devices
5. Laser ablation is also a popular use for laser marking systems. In this case the laser is used to remove a layer of paint, anodized or some other material covering the surface of the part. For example this process is used to create bear metal contact points on a painted part, to allow battery connection as in cell phones, or to remove paint for identification of parts and manufacturer details.
