laser marking and laser etching on glass for industrial applications

by:Qingyu     2020-03-17
The marking of industrial glass has been made for hundreds of years.
In the past, the methods used include ink seal marking, sandblasting, gas sand, acid etching, marking, etc.
Industrial applications for Glass marking include: 1.
Mark safety information on safety glass used in commercial and residential buildings.
This includes the glass area around the door and/or entrance and exit location. 2.
Glass marking for commercial and residential buildings to identify glass or door manufacturers [
For product identification and marketing/sales activities]3.
Mark of head light or tail light lens in automotive application for manufacturer name, year of manufacture and/or part number.
It is also used in the manufacture of television for marking mirrors and lenses. 4.
Marking of serial number, product identification, or other manufacturing information, used to prevent theft and verification of warranty claims.
Marking the serial number, part number, text, or bar code allows tracking of parts during production until final assembly and shipment. The traditional method of glass marking involves contact with the surface of the glass product, so that the product can withstand pressure and potential damage.
Co2 lasers provide significant advantages for the marking of glass products.
RF excitation sealed beam Co2 laser coupled with galvo head and software provides the fastest, cleanest, and most reliable method for marking and etching glass.
Co2 laser can mark glass with bar code laser, especially 2-
D or data matrix barcode, which can be easily coupled with the visual system for reading the data contained in the barcode.
The use of bar codes on glass allows the product to be tracked throughout the production process until final assembly.
This helps to ensure the continuous uninterrupted supply of products.
Laser marking or laser etching barcodes can also be used for identification purposes and verification after the product is sold.
This helps to eliminate warranty costs associated with counterfeit or unauthorized products.
During the manufacturing process, the visual system can also read the Co2 laser of the marking or laser etching barcode to determine the identity of the part.
For example, the prescription strength of the glasses lens, or the type of headlight lens used by Honda Civic.
This ensures that parts are correctly classified and used throughout the manufacturing process, and that the production of the correct number of parts is sold according to the expectations of the final assembly.
Compared with traditional methods, the progress of glass Co2 laser marking is very extensive.
These include: oNo contact with the part, such as in the marking method, thereby reducing the possibility of damage and damage to the part, and the maintenance required to eliminate the marking solvent, for example, in the case of ink marking or ink printing system, dilution or detergent used for purchase and inventory, thus greatly reducing the operating cost, and eliminates the need for continuous maintenance related to these various ink printing technologies, as they may be tilted or rotated horizontally, resulting in the image SquareoNo or not squareoNo to appear on the printed glass needs to stop the glass in place and ensure a firm fit with the rubber mask, like the Airgrit markingoWith Co2 laser mark for industrial glass applications, it is marked on the plane [while moving].
If you stop marking or mark as \"square\", you can etching five to eight lines of text with less than 0 laser plus a logo.
In the second Co2 laser marking, there is no necessary supplies and there is no second process for cleaning or maintenance.
Different words, different logos, different shapes, etc.
In industrial applications, the mouse 2 laser mark of the glass can be completed by simple mouse click and drag commands, which is the fastest, most effective and lowest cost method to mark the product.
