According to statistics, China is the world's largest producer of TV sets, recorders, VCD players, telephones, electronic watches, calculators, refrigerators, air conditioners, etc. It is a program-controlled switch, PC, mobile phone, and soft disk. A major producer of products such as drives, displays, computer boards, and mice. The wide range of electronic products and easy to unify manufacturing standards provide a huge space for laser marking.
Laser marking principle:
"Heat processing" - a laser beam with a higher energy density (which is a concentrated energy flow) that illuminates the surface of the material being processed, absorbs the laser energy on the surface of the material, and generates a thermal excitation process in the illuminated area, thereby causing the surface of the material (or coating) temperature rises, resulting in metamorphosis, melting, ablation, evaporation and so on.
"Cold processing" - (ultraviolet) photons with very high load energy can break chemical bonds in materials (especially organic materials) or surrounding media to cause non-thermal process damage. This cold working has special significance in laser marking processing because it is not thermal ablation, but does not cause "thermal damage" side effects, and the cold peeling of the chemical bond is broken, so that the inner layer and the vicinity of the surface to be processed are not Produces heat or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit a thin film of a chemical on a substrate material to create a narrow trench in the semiconductor substrate.
Laser marking features:
Wide range of applications, a variety of materials (metal, glass, ceramics, plastics, leather, etc.) can be marked with permanent high quality. No action on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material. It can be used for marking of devices such as integrated circuits, resistors, capacitors, crystals, diodes, and triodes.
Laser-printed labels are ubiquitous. A large number of laser-printed labels are required in offices, supermarkets, and factories. The main market segments for laser-printed labels are postal, trademark, and bar code labels. Because it can add value to the company's products and diversify products, it is popular among people from all walks of life. In addition, more and more companies are considering adding laser tags to their products to bring them higher profits.
When considering the development and trend of the laser label market, Steve Brocker, sales manager of Western States Envelope in the United States, believes that it should be positioned on existing customers. He said: "If we want to develop a market for laser tags, we should start with existing customers and ask them how they printed their trademarks so that they can deal with them more effectively. In order to win more sales markets. We should help our customers to make full use of the printing characteristics of trademarks to add value to their products.” Many corporate managers agree with this view. They think it is difficult to enter a business field that does not use laser tags. experience of. To solve this problem, some improvements should be made in their existing printing systems. First, the publisher needs to find out what the customer's printing requirements are, where their business direction is, and how to solve if there is a problem. Then locate the manufacturers that have a large demand for bar code trademarks, which will produce and send a large number of products. If they have a lot of useful information on the barcode, they can save a lot of time and money.
The best way to determine if a customer can benefit from a barcode is to ask how much they are sending. If the quantity does not reach a certain level, it is recommended not to use a barcode. However, if the customer already uses the barcode, the company that produces the barcode needs to be clear: are they on-demand or in volume production? How many inventory products are waiting to be labeled? How large is the amount of labels printed in the year? Will the amount of labels be increased soon?
For the first question, thermal transfer technology is the best choice if the customer prints the mark on demand; if it is mass produced, the laser label is ideal. For those customers who print less than one million trademarks a year, a laser-labeled solution can be used. For those customers with a large print volume, a single-jet laser label with continuous transfer is recommended. Barcodes aren't the only way to grab the laser label market, and postal and office applications can also get a lot of money. Brocker believes that printing laser labels with two- and four-color icons is an effective way to add value to customers' products and is an ideal solution. For example, when a customer needs to print a color icon on their company's envelope, instead of wasting money printing the color icon directly on the envelope, it is better to print the color logo on the laser label and then paste the laser label on the envelope at any time. Reduced costs for customers.
If the order is successfully signed with the customer, the company will begin to design a trademark that meets the customer's needs. Whether the customer is using a barcode or any other type of trademark, the customer's needs must be fully understood. One type of product is often used in office laser tags, namely CD-R and CD-RW, which are mainly used to copy and transmit information, often used in multimedia advertising presentations. In order to benefit from the trademark market, companies that operate trademarks should try to find customers who use such products and provide them with two- and four-color laser-printed trademarks for archiving and presentation. Customers who use dot matrix printers, especially those who print barcodes, have another market opportunity for laser tags. At present, dot matrix printers are on the verge of extinction, while laser printers provide clearer images, so the scannable images reproduced by laser printers make barcode scanning more accurate and look more professional. Laser-printed labels can also be die-cut into a variety of shapes as needed, increasing its identity and user flexibility. Another aspect of the dot matrix printing market that does not meet customer needs is that customers often need multiple trademarks at the same time. With a dot matrix printer for printing, customers typically only print one logo at a time through the printer. With a laser printer, end users can print multiple trademarks on a single sheet of paper and match them to a variety of die-cutting equipment. This greatly saves time spent on arranging trademarks and greatly reduces human error. When the label manufacturer identifies who their customer object is and what type of product they are producing, it is necessary to determine what type of laser label adhesive to use. The temperature of the hot melt wire on the laser printer is heated to 250 ° C ~ 300 ° C, so that the substrate and adhesive are well bonded together without any damage to the label. There are now many types of adhesives that meet such conditions. Laser-printed labels will undoubtedly be a hot spot in the market.
