Laser marking machine, laser laser engraving machine is applied in leather clothing, food packaging, shell nameplate, anti-counterfeiting code, laser laser machine manufacturer, laser laser engraving machine, Dongguan laser marking machine. The semiconductor laser marking machine side is commonly used in auto parts, glasses, and chips, because he can do deep engraving.
Laser technology has become an important application market in recent years, while also meeting the development needs of printing large amounts of data on even smaller plastic parts. Printing two-dimensional barcodes requires more accuracy and clarity than previously used barcodes. Laser marking meets these requirements, and in the 0.001 inch range, the size and position of the dots can be repeated - these properties are difficult to achieve with embossing or ink printers. The decorative thermoplastics with laser markings took longer to be recognized than expected a decade ago.
Even so, laser processing technology has replaced ink marking techniques (such as embossing and inkjet printing) in some applications, and the situation has changed. At present, the so-called "non-aesthetic" application is estimated to account for 90% of the plastic laser marking. Some markings are made with a carbon dioxide laser marking machine, including part model, date of manufacture and expiration date. The successful commercialization of laser marking includes the marking and cutting of graphics and text in the fields of garment accessories, leather, food and beverage packaging, electronic components, handicraft processing, and glass stone processing.
Suitable for marking large non-metallic materials, such as paper packaging, plastic products, label paper, leather fabrics, glass ceramics, resin plastics, bamboo and wood products, PCB boards, etc. Usually these labels are black on a transparent or light background. The letters and numbers, or on a black background are pure white marks. “Aesthetic” laser markings account for 10% of the market and have great potential for replacing ink technology. This is a typical white mark on black engineering plastics, printed on a solid-state Nd:YAG laser machine, which is easy to program and is suitable for clear marking of products in any shape. The initial applications include craft gifts, furniture, leather garments, advertising signs, model making, food packaging, electronic components, medical packaging, printing plates, and shell nameplates. Environmental issues such as production date, logo, and security code on paper, wood and plastic materials are also another driving force for the development of laser technology.
